Confidential Administrator’s Guide 9 Chapter 1 Basic Administration Tasks This chapter describes the various tasks that you can perform to effectively manage installation or perform additional configuration and maintenance operations for ArcSight Express components. The following topics are covered here: The Home Directory for Components on the Appliance The home directory, referred to as <ARCSIGHT_HOME> for each component on the ArcSight Express appliance is as follows: Manager: /opt/arcsight/manager CORR-Engine: /opt/arcsight/logger/current/arcsight/logger Web: /opt/arcsight/web Starting Components Start the Manager from a command or console window, or set up the Manager as a daemon. The remainder of this section provides more information about command line options you can use to start up, shut down, configure, or reconfigure ArcSight Express components. In addition, it provides information about setting up the Manager as a daemon, if you didn’t originally configure the Manager that way. “The Home Directory for Components on the Appliance” on page 9 “Starting Components” on page 9 “Reducing Impact of Anti-Virus Scanning” on page 11 “License Tracking and Auditing” on page 11 “Licensed EPS Compliance” on page 12 “ArcSight System Tasks” on page 13 “Setting up a Custom Login Banner” on page 13
1 Basic Administration Tasks 10 Administrator’s Guide Confidential Starting the ArcSight Manager To start the Manager from the command line, if it’s not configured to run either as a daemon or a service: Start the Manager by running the following command as user arcsight: /sbin/service arcsight_services start manager When you start the Manager as a service, to monitor whether it has successfully loaded, use the command: cd ARCSIGHT_HOME;tail -f logs/default/server.std.log Stopping the ArcSight Manager Stop the Manager service by running the following command as user arcsight: /sbin/service arcsight_services stop manager Starting the ArcSight Console To start up the ArcSight Console: 1 Open a command window or shell window on <ARCSIGHT_HOME>/bin. 2 Type in the following line and press Enter. ./arcsight console Reconnecting ArcSight Console to the Manager If the ArcSight Console loses its connection to the Manager—because the Manager was restarted, for example—a dialog box appears in the ArcSight Console stating that your connection to the Manager has been lost. Wait for the Manager to finish restarting, if applicable. Click Retry to re-establish a connection to the Manager or click Relogin. Starting ArcSight Web Access ArcSight Web through the Management Console. Starting the Management Console To start the console from a supported browser enter the following URL: https://<hostname>:8443/ Where <hostname> is the host name or IP address of the Manager that you specified when you first configured ArcSight Express. The connection to the Manager cannot be re-established while the Manager is restarting. In some cases, a connection cannot be established without resetting one or both machines. Clicking Retry may display connection exceptions while the Manager is restarting, or as the connection is re-established.
1 Basic Administration Tasks Confidential Administrator’s Guide 11 Starting ArcSight SmartConnectors This procedure is just for SmartConnectors that are not running as a service. If you are using the Connector Management feature to manage this connector, you probably do not need to use this command. It’s a good idea for the ArcSight Console to be running, so that you can see the status of the configured SmartConnectors and view messages as they appear on the Console. To start up an ArcSight SmartConnector: 1 Open a command window or terminal box and navigate to the connector’s /current/bin directory. 2 Type in the following line and press Enter: ./arcsight agents The connector in that folder starts. Starting Connector Management Services To start the Connector Management Service run the following command as user arcsight: /sbin/service arcsight_services start conapp To start the service for a connector container run the following command as user root: /sbin/service arcsight_services start connector_<N> ...where <N> is the number of the container whose service you want to start. Reducing Impact of Anti-Virus Scanning Files in certain directories are updated frequently; for example, the log directory. When an anti-virus application monitors these directories, it can impact the system in these ways:  It can place a large and constant load on the CPU of the machine.  It can slow the system down, because frequent scanning can impede writes to disk. Therefore, we recommend that you exclude the following directories (and any subdirectories under them) in <ARCSIGHT_HOME> from the virus scan list:  caches/server  logs  system  tmp  user, but include the user/agent/lib directory in the scan  archive License Tracking and Auditing The system automatically maintains a license audit history that allows you to see how many licenses are in use. When users log into the Console they receive a warning notifying them if they have exceeded their current license. ArcSight Express creates an internal
1 Basic Administration Tasks 12 Administrator’s Guide Confidential audit event for each licensable component to help users track which areas have been exceeded. There are licensing reports on individual features. These reports are located in /All Reports/ArcSight Administration/ESM/Licensing/. The reports provide a summary for the number of Actors, Assets, Users, Devices, and EPS identified over the last week. Licensed EPS Compliance By default, your events per second (EPS) throughput is monitored once every 24 hours and an average EPS value is calculated for that period. Your license places a limit on this average. It also places a limit on the number of times you are allowed to exceed the EPS limit over a period (rolling window) of days. In a given window, each time your EPS throughput exceeds the licensed limit, this violation is recorded. When the violations exceed the number allowed, your installation becomes noncompliant and you are temporarily prevented using certain functionality (as listed below). For Example:, suppose your license is set up as follows:  Number of incoming EPS allowed = 1000 EPS  Number of times allowed to exceed 1000 EPS = 5 times  Period over which you are allowed to exceed the 1000 EPS limit 5 times = 7 days If you exceed your maximum EPS limit (1,000) more than five times in seven days, punitive action starts. The punitive action is that access to the resources in the following list is disabled for an hour for every day you’ve exceeded the EPS limit in the seven day period, up to a maximum of five hours. It starts as soon as you exceed your limit. The EPS license compliance is enforced on the following viewers.  Channels (event and resource channels)  Data monitors  Query viewers and query viewers in dashboard  Pattern Discovery (creating new snapshots)  Event graph from channel  Global or Political Image Viewer in the Active Channel view  Category model view  Custom view Dashboards on the Console and ArcSight Web (but not the Management Console) Nothing happens to any of the above viewers if they already exist in viewer table when you exceed the License limit. However, if you attempt to create a new viewer, stop and restart a channel, create or edit a data monitor, and so on, you get an error message dialog that you have exceeded your license. In ArcSight Web only channels and dashboard are affected. As days continue to elapse, when the EPS limit violation is calculated to be five times or less in the past seven days, you become compliant and the features are automatically re-enabled.
1 Basic Administration Tasks Confidential Administrator’s Guide 13 ArcSight System Tasks These system tasks are scheduled to run automatically one or more times per day, depending on the task. You can control some of these schedules indirectly, for example by changing the retention period. AUP Updater: This task runs in the manager and pushes to connectors any updated AUP packages it might have. Dependent Resource Validator: This task runs validations on resources in the system and disables the ones that have problems. PurgeStaleMarkSimilarConfigs: This task does maintenance work on the 'mark similar' annotation criteria, removing the ones that are stale. Resource Search Index Updater: This task updates the resource search index. Sortable Fields Updater: This task keeps sortable event fields in sync, based on the current indices in the database. Table Stats Updator: This task updates statistics on the non-partitioned schema tables, which includes the resource tables. Setting up a Custom Login Banner You can configure the Manager to return a custom login message to display for users logging in to the ArcSight Console. Set the following property in server.properties: auth.login.banner=config/loginbanner.txt This property configures the Manager to send the text from the file <ARCSIGHT_HOME>/config/loginbanner.txt whenever a user runs the ArcSight Console. (Changes to the properties file take effect the next time the Manager is started.) Create a text file named loginbanner.txt in the <ARCSIGHT_HOME>/config directory. This feature is often used to display a legal disclaimer message. Users must close the message window before they can log in.
1 Basic Administration Tasks 14 Administrator’s Guide Confidential
Confidential Administrator’s Guide 15 Chapter 2 Configuration This chapter describes the various tasks that you can perform to manage the component configuration. The following topics are covered in this chapter: Managing and Changing Properties File Settings Various components use properties files for configuration. Many sections of this documentation require you to change properties in those files. Some of the properties files are also modified when you use one of the configuration wizards. Property File Format Generally, all properties files are text files containing pairs of keys and values. The keys determine which setting is configured and the value determines the configuration value. For example, the following property configures the port on which the Manager listens: servletcontainer.jetty311.encrypted.port=8443 Blank lines in this file are ignored as well as lines that start with a pound sign ( # ). Lines that start with a pound sign are used for comments. “Managing and Changing Properties File Settings” on page 15 “Adjusting Console Memory” on page 21 “Adjusting Pattern Discovery Memory” on page 21 “Installing New License Files Obtained from HP” on page 21 “Configuring Manager Logging” on page 22 “Understanding SSL Authentication” on page 31 “Reconfiguring the ArcSight Console after Installation” on page 72 “Reconfiguring Connectors” on page 72 “Reconfiguring ArcSight Manager” on page 72 “Managing Password Configuration” on page 73 “Advanced Configuration for Asset Auto-Creation” on page 78 “Compression and Turbo Modes” on page 81 “Sending Events as SNMP Traps” on page 82 “Asset Aging” on page 84 “Configuring Actors” on page 86
2 Configuration 16 Administrator’s Guide Confidential Defaults and User Properties Most configuration items in various components consist of at least two files. The first, is the defaults properties file, such as server.defaults.properties. It contains the default settings. You shoule not modify these files; use them as a reference. The second file, is the user properties file, such as server.properties. It can contain any properties from the defaults properties file, but the property values in this file override those in the defaults file. Thus, it contains settings that are specific to a particular installation. Typically, the user properties file for a component is created and modified automatically when you configure the component using its configuration wizard. Because the user properties file contains settings you specify to suit your environment, it is never replaced by an upgrade. If an upgrade, such as a service pack or a version update, changes any properties, it does so in the defaults file. The following table lists the most important properties files. For information on Connector Management properties files (container and connector properties), refer to the Connector ManagementUser’s Guide. Editing Properties Files When you edit a *.properties file, first look for the *.defaults.properties file. Copy the property you want to edit from *.defaults.properties to *.properties and change the setting to your new value in *.properties. When the same property is defined differently in each file, the system uses the value in *.properties. This ensures that when you install an upgrade, and the *.defaults.properties file is updated, the properties you customized are retained unchanged in *.properties. You can edit the properties using any simple text editor, such as Notepad, on Windows. Make sure you use one that does not add any characters such as formatting codes. If you configured the Console and SmartConnectors using default settings in the configuration wizard, a user properties file is not created automatically for that component. If you need to override a setting on such a component, use a text editor to create this file in the directory specified in the above table. When you edit a property on a component, you must restart the component for the new values to take effect except for the dynamic Manager properties listed in the next section. If you change a communication port, be sure to change both sides of the connection. For example, if you configure a Manager to listen to a different port than 8443, be sure to Default Properties User Properties Purpose config/server.defaults. properties config/server.properties Manager Configuration config/console.defaults. properties config/console.properties ArcSight Console Configuration config/client.defaults. properties config/client.properties ArcSight Common Client Config config/agent/agent. defaults.properties user/agent/agent.properties SmartConnector Configuration

Every time the manager-reload-config command is successful, a copy of the server.properties file it loaded is placed in <ARCSIGHT_HOME>/config/history for backup purposes. The server.properties file in <ARCSIGHT_HOME>/config/history is suffixed with a timestamp and does not overwrite the existing versions, as described in the following example. Example Manager M1 starts successfully for the first time on September 26, 2012, at 2:45 p.m. A backup copy of its server.properties file is written to <ARCSIGHT_HOME>/config/history with this timestamp: server.properties.2012_09_26_14_45_27_718 On September 27, 2010, the M1 administrator adds the following property to the server.properties file: notification.aggregation.max_notifications=150 When the administrator runs the manager-reload-config command at 1:05 p.m. the same day, it runs successfully because this property can be loaded dynamically. As soon as the updated server.properties file is loaded in M1’s memory, a backup copy of the updated server.properties file is written to <ARCSIGHT_HOME>/config/history with appropriate timestamp. Now, <ARCSIGHT_HOME>/config/history contains these two backup files:
2 Configuration Confidential Administrator’s Guide 19 server.properties.2012_09_26_14_45_27_718 server.properties.2012_09_27_01_05_40_615 On September 28, 2012, the M1 administrator adds this property to the server.properties file: notification.aggregation.time_window=2d As this property can be also loaded dynamically, similar to the previous change, once the updated server.properties is loaded in M1’s memory, a backup copy of the server.properties file is written to <ARCSIGHT_HOME>/config/history with appropriate timestamp. Now, <ARCSIGHT_HOME>/config/history contains these three backup files: server.properties.2012_09_26_14_45_27_718 server.properties.2012_09_27_01_05_40_615 server.properties.2012_09_28_03_25_45_312 On September 39, 2012, the M1 administrator updates the whine.notify.emails property in the server.properties file. When he runs the manager-reload-config command, the command fails because this property cannot be loaded dynamically. As a result, these things happen:  The updated server.properties file is not loaded into M1’s memory, however, changes made to it are not reverted.  M1 continues to use the properties that were loaded on September 29th.  No backup copy is made. The <ARCSIGHT_HOME>/config/history directory continues to contain the same three backup files: server.properties.2012_09_26_14_45_27_718 server.properties.2012_09_27_01_05_40_615 server.properties.2012_09_28_03_25_45_312 The changes made on September 30th are not effective until M1 is restarted. Changing Manager Properties Dynamically To change any of the properties listed previously, do these steps: 1 Change the property in the server.properties file and save the file. 2 (Optional) Use the –diff option of the manager-reload-config command to view the difference between the server properties the Manager is currently using and the properties loaded after you run this command: arcsight manager-reload-config –diff 3 Run this command in <ARCSIGHT_HOME>/bin to load the new values for the properties you changed: The -diff option compares all server properties—default and user properties. For all options available with the manager-reload-config command, see Appendix A‚ Administrative Commands‚ on page 105.
2 Configuration 20 Administrator’s Guide Confidential arcsight manager-reload-config If this command fails with a warning, it indicates that you are changing properties that require a Manager restart before those changes can take effect. When you get such a warning none of the property changes, including the ones that can be reloaded without restarting the Manager, are applied. You can do one of the following in this situation:  Revert changes to properties that cannot be loaded without restarting the Manager and rerun the manager-reload-config command.  Force an update of all properties using the –as option, as follows: arcsight manager-reload-config -as When you use the -as option, the properties that can be changed without restarting the Manager take effect immediately. The properties that require a Manager restart are updated in the server.properties but are not effective until the Manager is restarted. For example, if you change auth.password.length.min to 7 and search.enabled to false, you get the above warning because only auth.password.length.min can be updated without restarting the Manager. If you force an update of the server.properties file, auth.password.length.min is set to 7, but search.enabled continues to be set to true until the Manager is restarted. Changing the Service Layer Container Port By default the service layer container port is 9090. You can change this port: 1 Modifying the following files located in the Manager’s <ARCSIGHT_HOME>:  /arcsight-dm com.arcsight.dm.plugins.tomcatServer_7.0.21/conf/server.xml  /config/proxy.rule.xml  /config/rewriteProxy.rule.xml Make sure to replace the references to port 9090 with an unused port number. 2 Restart the Manager. Securing the Manager Properties File The Manager’s server.properties file contains sensitive information such as database passwords, keystore passwords, and so on. Someone accessing the information in this file can do a number of things, such as tampering with the database and acting as a Manager. As a result, the server.properties file must be protected so that only the user account under which the Manager is running is able to read it. For example, in Unix you can use the chmod command: chmod 600 server.properties This operation is performed during the Manager installation. As a result, only the owner of the file (which must be the user that runs the Manager) may read or write to the file. For all other users, access to the file is denied. Be careful in using the –as option to force reload properties. If an invalid static change is made, it may prevent the Manager from starting up once it reboots.
2 Configuration Confidential Administrator’s Guide 21 Adjusting Console Memory Because the ArcSight Console can open up to ten independent event-viewing channels, out-of-memory errors may occur. If such errors occur, or if you simply anticipate using numerous channels for operations or analysis, please make the following change to each affected Console installation. In the bin/scripts directory, in the console.sh configuration file, edit the memory usage range for the Java Virtual Machine. Adjusting Pattern Discovery Memory By default, Pattern Discovery limits its memory usage to about 4 GB of memory. However, if the search for patterns involves too many transactions and events, the task can run out of memory and abort. You can control the memory limit indirectly by changing the maximum number of transactions and events the Pattern Discovery task can hold in memory. The settings for these values are in the server.defaults.properties file in the config folder.  patterns.transactionbase.max — The maximum number of transactions allowed in memory. If you exceed this number, these transactions are stored as page file. The default is 10000.  patterns.maxSupporterCost — The maximum number of supporters allowed in memory. If you exceed this number, the Pattern Discovery task aborts. The default is 80000.  patterns.maxUniqueEvents — The maximum number of unique events allowed in memory. If you exceed this number, the Pattern Discovery task aborts. The default is 20000. If the Pattern Discovery task aborts, a message to that effect appears in the console. Run the Pattern Discovery task again after increasing the Pattern Discovery memory usage limits. You can increase the memory usage limit by increasing the three values proportionally. For example, to add 25 percent more memory capacity, you would change the values to:  patterns.transactionbase.max=12500  patterns.maxSupporterCost=100000  patterns.maxUniqueEvents=25000 You can edit the properties file using a regular text editor. After changing any of these values, restart the manager for them to take effect. Installing New License Files Obtained from HP You receive new license files packaged as .zip files and sent via e-mail from HP. To deploy the new license file you obtained from HP, please follow the steps below: 1 Go to the Management Console’s Administration tab and find the License Information section, under Configuration Management. 2 In the License File field specify or browse to the lic or zip file containing the license you want to upload. 3 Click Upload to upload a new license.
2 Configuration 22 Administrator’s Guide Confidential 4 After uploading, the Management Console asks you if you want to Restart, which restarts certain ArcSight server processes. You can choose to restart later. If so, when you are ready, select Server Management in the accordion panel under Configuration Management, and click Restart, at the bottom. You will have to log in again. If you are using ArcSight Express on an appliance, restart the Manager by running the appropriate command, as describe in “ArcSight_Services Command” on page 106. Configuring Manager Logging The Manager outputs various types of information to log files. By default, the logs are located in: <ARCSIGHT_HOME>/logs/default/ Various Manager utilities write logging information to different sets of log files. Each of those sets can consist of multiple files. The number and size of the log files are configurable, a typical setting is 10 files with 10 megabytes each. When a log file reaches a maximum size, it is copied over to a different location. Depending on your system load, you may have to change the default settings. To make changes to the logging configuration, change the log channel parameters. The default log channel is called file. For the main Manager log file, called server.log, the following server.properties settings are used: # Maximum size of a log file. log.channel.file.property.maxsize=10MB # Maximum number of roll over files. log.channel.file.property.maxbackupindex=10 The first setting affects the size of each individual log file; the second setting affects the number of log files created. The log file currently in use is always the log file with no number appended to the name. The log file with the largest number in its extension is always the oldest log file. All of the log files are written to the <ARCSIGHT_HOME>/logs/default directory. The Manager and its related tools write the following log files: Description server.log* The main Manager log. server.status.log* System status information, such as memory usage etc. server.channel.log* Active Channel logs. server.std.log* All output that the Manager prints on the console (if run in command line mode) server.pulse.log* The Manager writes a line to this set of logs every ten seconds. Used to detect service interruptions.
2 Configuration Confidential Administrator’s Guide 23 For information on Connector Management logs, refer to the Connector Management User’s Guide. Sending logs and diagnostics to HP Support Customer Support may request log files and other diagnostic information to troubleshoot problems. The Send Logs utility automatically locates the log files and compresses them. You can send the compressed files to Customer Support.  You can run this utility as a wizard directly from the Console interface (GUI) in addition to the command-line interface of each component.  Optionally, gather diagnostic information such as session wait times, thread dumps, and database alert logs about your ArcSight Express system, which helps HP Customer Support analyze performance issues on your ArcSight Express components.  When you run this utility from the Console, Manager, or Web, you can gather logs and diagnostic information for all components of the system. Guidelines for using the Send Logs utility Keep these guidelines in mind when using the Send Logs utility:  You can be connected as any valid user on an ArcSight Express component to collect its local logs; however, you must have administrator access to collect logs from other components. For example, if you are connected as user ‘joe’ to the Console, you can collect its logs. But if you need to collect logs for the Manager and the database, you must connect to the Console as the administrator.  SmartConnectors must be running version 4037 or later to remotely (using a Console or the Manager) collect logs from them.  You can only collect local logs on SmartConnectors or the CORR-Engine . The Send Logs utility only collects logs for the component on which you run it. In order to collect the CORR-Engine logs, the Manager needs to be running.  You can run the Send Logs utility on a component that is down. That is, if the Database is down, you can still collect its logs using this utility. If the Manager is down, you can only collect its local logs. However, if you need to collect the database logs as well, use the arcdt command on the Manager. For more information, see Appendix A‚ Administrative Commands‚ on page 105.  All log files for a component are gathered and compressed. That is, you cannot select a subset of log files that the utility should process. server.sql.log* If database tracing is enabled, the SQL statements are written to this set of log files. execproc.log* Log information about externally executed processes (only on some platforms) serverwizard.log* Logging information from the arcsight managersetup utility. You can also use the arcdt command to run specific diagnostic utilities from the Manager command line. For more information, see Appendix A‚ Administrative Commands‚ on page 105. Description
2 Configuration 24 Administrator’s Guide Confidential  The Send Logs utility generates a compressed file on your local system that you can send to Customer Support by e-mail, if they request it.  You can review the compressed file to ensure that only a desired and appropriate amount of information is sent to support.  You can remove or sanitize information such as IP addresses, host names, and e-mail addresses from the log files before compressing them. The options are:  Send log as generated This option, the default, does not remove any information from the logs files.  Only remove IP address This option removes IP addresses, but not host names or e-mail addresses, from the logs files.  Remove IP address, host names, e-mail addresses This option removes all IP addresses and enables you to specify a list of host- name suffixes for which all host names and e-mail addresses are removed from the logs. For example, if you specify ‘company.com’ as a host-name suffix to remove, the Send Logs utility removes all references to domains such as ‘www.company.com’ and e-mail addresses such as ‘john@company.com’ from the logs. Gathering logs and diagnostic information When you run the Send Logs utility on SmartConnectors, it gathers logs and diagnostic information (if applicable) for only those components. However, when you run this utility on ArcSight Console, Manager, or ArcSight Web, you can gather logs and diagnostic information for all or a selected set of ArcSight Express components. To run this utility on SmartConnectors, enter this in <ARCSIGHT_HOME>/bin: ./arcsight agent sendlogs To gather logs and diagnostic information for all or a selected set of components, do one of the following:  On the ArcSight Console, click Tools > SendLogs.  Enter this command in <ARCSIGHT_HOME>/bin on Console, Manager, or Web: ./arcsight sendlogs The above action starts the Send Logs wizard. In the wizard screens, perform these steps: The Send Logs wizard remembers most of the choices you make when you run it for the first time. Therefore, for subsequent runs, if you choose to use the previous settings, you do not need to re-enter them.
2 Configuration Confidential Administrator’s Guide 25 1 Decide whether you want the wizard to gather logs only from the component on which you are running it or from all components. If you select Use current settings to gather logs. logs for all components are gathered thus: If this is the first sendlogs is run after installation, then all the logs are gathered. If this is not the first sendlogs is run, then it uses the same setting as the previous run. a Enter the Manager’s login information. b Go to Step 2 on page 28. If you selected Change/Review settings before gathering logs., you get the option to select the components for which you want logs gathered. Select whether you want only the local (the component from where you ran the Send Logs utility) logs selected or you want logs from other components collected too. Local logs only:
2 Configuration 26 Administrator’s Guide Confidential If you selected Local logs only, you are prompted to either choose a time range or include all time ranges. If you selected Include all time ranges, go to Step 2 on page 28. If you selected Choose a specific time range, you are prompted to enter a start time and end time - a time range for which the wizard gathers the logs. Go to Step 2 on page 28. Logs from other components (Requires Manager credentials): If you select Logs from other components (Requires Manager credentials), you are prompted to choose the components. a Select the components and the time range for which you want to gather logs. In addition, select whether you want to run the diagnostic utilities to gather additional information for those components. (The options below might be labeled

If you choose to specify the diagnostic utilities to run, you are prompted to select the utilities from a list in a later screen. The diagnostic utilities you can select are described in Appendix A‚ arcdt‚ on page 110. b If you chose to gather logs from the SmartConnectors, select those SmartConnectors in the next screen. At a minimum, the SmartConnectors should be running version 4037 or later.
2 Configuration 28 Administrator’s Guide Confidential c If you chose to select the diagnostic utilities you want to run earlier in this wizard, select them in the next screen. d Go to Step 2 on page 28. 2 Select whether you want to sanitize the logs before collecting them. For more information about sanitizing options, see “Guidelines for using the Send Logs utility” on page 23. If you choose Keep Log sanitization settings, go to Step 3 on page 30.
2 Configuration Confidential Administrator’s Guide 29 If you choose Change/Review Logs sanitization settings, you are prompted to select what you want to sanitize. If you chose one of the first two options, go to Step 3 on page 30. If you selected Remove IP addresses, host names, and e-mail addresses (Slower), you are prompted to enter what you want removed. Click Add to add a suffix to remove. Highlight an entry and click Remove to remove it from the list.
2 Configuration 30 Administrator’s Guide Confidential 3 Enter the Customer Support incident number. The Send Logs utility uses this number to name the compressed file it creates. Use the incident number that Customer Support gave you when you reported the issue for which you are sending the logs. Doing so helps Customer Support relate the compressed file to your incident. In case you do not have an incident number at this time, you can continue by entering a meaningful name for the compressed file to be created. Once you obtain the incident number from Customer Support, you can rename the file with the incident number you received. 4 Click Next to start the compression. Most of the values you entered during the first run of the Send Logs wizard are retained. The next time you run this wizard, you need to enter only a few settings.
2 Configuration Confidential Administrator’s Guide 31 5 Click Finish in the last screen. Understanding SSL Authentication Secure Socket Layer (SSL) technology is used for communication between the Manager and its clients—Console, SmartConnectors, and ArcSight Web. SSL is also used between ArcSight Web and the web browsers that communicate with it. SSL enables the Manager (referred to as a “server”) to authenticate to its clients and communicate information over an encrypted channel, thus providing the following benefits:  Authentication—Ensuring that clients send information to an authentic server and not to a machine pretending to be that server.  Encryption—Encrypting information sent between the clients and the server.  Data Integrity—Hashing information to prevent intentional or accidental modification. By default, clients submit a valid user name and password to authenticate with the server; however, these clients can be configured to use SSL client authentication. Note that SSL is not used between the Manager and the Database.
2 Configuration 32 Administrator’s Guide Confidential Terminology These terms are used in describing and configuring SSL:  Certificate A certificate contains the public key, identifying information about the machine such as machine name, and the authority that signs the certificate. SSL certificates are defined in the ISO X.509 standard.  Key pair A key pair is a combination of a private key and the public key that encrypts and decrypts information. A machine shares only its public key with other machines; the private key is never shared. The public and private keys are used to set up an SSL session. For details, see “How SSL Works” on page 42.  SSL server-SSL client An SSL session is set up between two machines—a server and a client. Typically, a server must authenticate to its clients before they send any data. However, in client- side SSL authentication, the server and its clients authenticate each other before communicating. The Manager is an SSL server, while SmartConnectors, Console, and browsers are SSL clients. ArcSight Web is an SSL client to the Manager and an SSL server to the web browsers that connect to it.  Keystore A keystore is an encrypted repository on the SSL server that holds the SSL certificate and the server’s private key. The following table lists the ArcSight Express component, the name of the keystore on that component, and its location. [1] When client-side authentication is used, a keystore exists on both the server and the client. [2] Make sure you do not change the keystore file name. The keytoolgui utility, used to perform a number of SSL configuration tasks, refers to a combination of an SSL certificate and private key as the key pair. The keytoolgui utility is discussed in “Tools for SSL Configuration” on page 36. Log File keystore File Name[2] Location of keystore Manager keystore <ARCSIGHT_HOME>/config/jetty ArcSight Web webkeystore <ARCSIGHT_HOME>/config/jetty Clients[1] (for client-side authentication) keystore.client <ARCSIGHT_HOME>/config
2 Configuration Confidential Administrator’s Guide 33  Truststore Truststore is an encrypted repository on SSL clients that contains a list of certificates of the issuers that a client trusts. When an issuer issues a certificate to the server, it signs the certificate with its private key. When the server presents this certificate to the client, the client uses the issuer’s public key from the certificate in its truststore to verify the signature. If the signature matches, the client accepts the certificate. For more details, see how SSL handshake occurs in “How SSL Works” on page 42. The following table lists the ArcSight Express component, the name of the truststore on that component, and its location. [1] The utilities that exist on the Manager machine such as archive are treated as clients of the Manager. The cacerts file on the Manager is used for authenticating the Manager to these clients. [2] When client-side authentication is used. [3] When client-side authentication is used, ArcSight Web contains two truststores— cacerts for connections to the Manager and webtruststore for connections to browsers. The keytoolgui utility, used to view a truststore, is discussed in “Tools for SSL Configuration” on page 36.

2 Configuration 34 Administrator’s Guide Confidential  Alias Certificates and key pairs in a keystore or a truststore are identified by an alias.  Truststore password The *.defaults.properties file contains the default truststore password for each ArcSight Express component (changeit). The password is in clear text and typically, you do not need to change it. To change or obfuscate it, use the changepassword utility, as described in Appendix A‚ Administrative Commands‚ on page 105. The following table lists the property name where the obfuscated truststore passwords are stored. *For client-side authentication ** If config/client.properties or user/agent/agent.properties does not exist, create it using an editor of your choice.  Keystore password Use a keystore password to encrypt the keystore file and use a truststore password to encrypt a truststore file. Without this password, you cannot open these files. The default is password for the Manager and ArcSight Web, and changeit for the ArcSight Console’s client keystore. The default password for the key pair for any component is the same as for the component’s keystore. You specify a keystore password when creating a key pair, which is discussed in later sections of this chapter. The password is obfuscated and stored in the ArcSight Express component’s *.properties file. The following table lists the property file Truststore Property File Property Name Client client.properties** ssl.truststore.password Manager* server.properties servletcontainer.jetty311.truststore .password.encrypted ArcSight Web webserver.properties servletcontainer.jetty311.truststore .password.encrypted Connector agent.properties** ssl.truststore.password
2 Configuration Confidential Administrator’s Guide 35 and the property name where the keystore password is stored for each component. The following table lists the property name where the obfuscated keystore passwords are stored. *For client-side authentication ** If config/client.properties or user/agent/agent.properties does not exist, create it using an editor of your choice.  NSS database password The default password for the Manager’s nssdb, the Console’s nssdb.client, and ArcSight Web’s webnssdb are all changeit. To change it, see “Changing the Password for NSS DB” on page 178.  Cacerts password The default password for cacerts ischangeit.  Cipher suite A set of authentication, encryption, and data integrity algorithms used for securely exchanging data between an SSL server and a client. The following cipher suites are enabled by default:  TLS_RSA_WITH_AES_128_CBC_SHA  SSL_RSA_WITH_3DES_EDE_CBC_SHA  SSL_RSA_WITH_RC4_128_MD5  SSL_RSA_WITH_RC4_128_SHA Other supported cipher suites are:  TLS_DHE_RSA_WITH_AES_128_CBC_SHA  TLS_DHE_DSS_WITH_AES_128_CBC_SHA  SSL_DHE_RSA_WITH_3DES_EDE_CBC_SHA  SSL_DHE_DSS_WITH_3DES_EDE_CBC_SHA  SSL_RSA_WITH_DES_CBC_SHA  SSL_DHE_RSA_WITH_DES_CBC_SHA  SSL_DHE_DSS_WITH_DES_CBC_SHA  SSL_RSA_EXPORT_WITH_RC4_40_MD5  SSL_RSA_EXPORT_WITH_DES40_CBC_SHA  SSL_DHE_RSA_EXPORT_WITH_DES40_CBC_SHA  SSL_DHE_DSS_EXPORT_WITH_DES40_CBC_SHA  SSL_RSA_WITH_NULL_MD5  SSL_RSA_WITH_NULL_SHA Keystore Property File Property Name Client* client.properties** ssl.keystore.password.encrypted Manager server.properties server.privatekey.password.encrypted ArcSight Web webserver.properties server.privatekey.password.encrypted Connector agent.properties** ssl.keystore.password.encrypted

During the SSL handshake, the client provides this list as the cipher suites that it can accept, in descending order of preference. The server compares the list with its own set of acceptable cipher suites, picks one to use based on its order of preference, and communicates it to the client. Tools for SSL Configuration Keytoolgui The keytoolgui utility enables you to perform a number of SSL configuration tasks on Windows. Some of these tasks are:  “Using Keytoolgui to Export a Key Pair” on page 36  “Using Keytoolgui to Import a Key Pair” on page 37  “Using Keytoolgui to Export a Certificate” on page 37  “Using Keytoolgui to Import a Certificate” on page 38  “Creating a keystore Using Keytoolgui” on page 40  “Generating a Key Pair Using Keytoolgui” on page 40  For information about managing certificates on a Connector Management container, refer to the Connector Management User’s Guide. The keytoolgui utility is available on all components and is located in the <ARCSIGHT_HOME>/bin/scripts directory of the component. (To run this tool on Unix, be sure to have X11 enabled.) To run keytoolgui, run this command in <ARCSIGHT_HOME>/bin: ./arcsight keytoolgui On SmartConnectors, use: ./arcsight agent keytoolgui Using Keytoolgui to Export a Key Pair 1 To start it, run the following from the Manager’s bin directory:

2 Configuration Confidential Administrator’s Guide 41 keytool The keytool utility is the command-line version of keytoolgui that you can use to manipulate the keystores and truststores directly. Use the keytool utility on UNIX environments without X11 or whenever a command-line option is more suitable. Use keytool -help for a complete list of all command options and their arguments. To use keytool, enter this command: arcsight keytool [option] –store <store value> where <store value> can be:  managerkeys—Manager keystore  managercerts—Manager truststore  webkeys—Web keystore  webcerts—Web truststore  ldapkeys—Manager LDAP Client keystore  ldapcerts—Manager LDAP Client truststore  clientkeys—Client keystore  clientcerts—Client truststore On SmartConnector hosts, use: arcsight agent keytool [option] –store <store value> The following is an example for creating a 2048-bit, RSA key-pair with the mykey alias that expires in 10 years (3650 days). arcsight keytool -v -genkeypair -alias mykey -validity 3650 -keyalg rsa -keysize 2048 -store managerkeys The following is an example for exporting the above key-pair as a "self-signed" RFC-1421 compliant ASCII certificate. arcsight keytool -exportcert -alias mykey -v -store managerkeys -rfc -file export_mykey.pem You can also SCP your keystore file to a computer where the ArcSight Console is installed and use keytoolgui to make changes before uploading back to the remote server. tempca The tempca utility enables you to manage the SSL certificate in many ways. To see a complete list of parameters available for this utility, enter this in <ARCSIGHT_HOME>/bin: ./arcsight tempca On SmartConnectors, use: ./arcsight agent tempca Two frequently performed operations using this utility are:  Viewing the type of certificate in use on the Manager:
2 Configuration 42 Administrator’s Guide Confidential ./arcsight tempca –i  Removing the Demo certificate from the list of trusted certificates, if applicable: ./arcsight tempca -rc How SSL Works When a client initiates communication with the SSL server, the server sends its certificate to authenticate itself to the client. The client validates the certificate by verifying:  The hostname is identical to the one with which the client initiated communication.  The certificate issuer is in the list of trusted certificate authorities in the client’s truststore (<ARCSIGHT_HOME>/jre/lib/security/cacerts) and the client is able to verify the signature on the certificate by using the CA’s public key from the certificate in its truststore.  The current time on the client machine is within the validity range specified in the certificate to ensure that the certificate is valid. If the certificate is validated, the client generates a random session key, encrypts it using the server’s public key, and sends it to the server. The server decrypts the session key using its private key. This session key is used to encrypt and decrypt data exchanged between the server and the client from this point forward.
2 Configuration Confidential Administrator’s Guide 43 The following figure illustrates the handshake that occurs between the client and Manager. With client-side authentication, the server requests the client’s certificate when it sends its certificate to the client. The client sends its certificate along with the encrypted session key. SSL certificates To replace an expired certificate, delete the expired certificate from the truststore, cacerts, first and then import the new certificate into cacerts. Since the common name (CN) for the new certificate is identical to the CN in the old certificate, you are not permitted have both the expired and the new certificate in the cacerts. To delete a certificate from the truststore, start the keytoolgui and navigate to the certificate, right-click on the certificate, and select Delete. Use the keytoolgui to import the new certificate into the truststore or cacerts. Types You can use three types of SSL certificates:  CA-signed
2 Configuration 44 Administrator’s Guide Confidential  Self-signed (applicable to default mode only)  Demo (applicable to default mode only) CA-signed certificates are issued by a third party you trust. The third party may be a commercial Certificate Authority (CA) such as VeriSign and Thawte or you might have designated your own CA. Because you trust this third party, your clients’ truststores might already be configured to accept its certificate. Therefore, you may not have to do any configuration on the client side. The process to obtain a CA-signed certificate is described in “Create a Key Pair for a CA-Signed Certificate” on page 49. You can create your own self-signed certificates. A self-signed certificate is signed using the private key from the certificate itself. Configure clients to trust each self-signed certificate you create. Comparing Self-signed and CA-signed certificates Self-signed certificates are as secure as CA-signed, however, CA-signed certificates scale better as illustrated in this example: If you have three SSL servers that use self-signed certificates, configure your clients to accept certificates from all of them (the three servers are three unique issuers). If you add a new server, configure clients again. However, if these servers use a CA-signed certificate, configure the clients once to accept the certificate. If the number of Managers grows in the future, you do not need to do any additional configuration on the clients. Viewing Certificate Information For certificates in the keystore, truststore, or cacerts, use the keytoolgui command to see certificate information. For the nssdb, nssdb.client, and webnssdb, usethe runcertutil command to view certificate information. See “runcertutil” on page 134, for more information. For the Manager certificate you can also use tempca -i command. ArcSight WebUsing a Self-Signed Certificate The procedure you follow depends on the number of Managers with which your clients communicate. For information about managing certificates on a Connector Management container, refer to the Connector Management User’s Guide. When clients communicate with one Manager To use a self-signed certificate for deployments in which clients communicate with only one Manager, perform these steps: 1 On the Manager, create a self-signed key pair: a In <ARCSIGHT_HOME>/bin, run this command: ./arcsight managersetup Steps to create a self-signed key pair may be different for a new Manager installation as the Configuration Wizard is launched automatically during the installation process.
2 Configuration Confidential Administrator’s Guide 45 b In the Manager Configuration Wizard, select Replace with new Self-Signed key pair. and click Next. c Enter information about the SSL certificate, as shown in this example. Click Next. d Enter the SSL keystore password for the certificate. Click Next.
2 Configuration 46 Administrator’s Guide Confidential Remember this password. You use it to open the keystore. e Step through the Configuration Wizard. At the end of the Configuration Wizard, these three things happen: i The Manager’s keystore, <ARCSIGHT_HOME>/config/jetty/keystore, is replaced with the one created using this procedure. ii A selfsigned.cer certificate file is generated in the <ARCSIGHT_HOME>/config/jetty directory. iii The newly generated self-signed certificate is added to the Manager’s truststore file, <ARCSIGHT_HOME>/jre/lib/security/cacerts. 2 Export the Manager’s certificate from <ARCSIGHT_HOME>/jre/lib/security/cacerts. 3 Make sure to copy the Manager’s certificate to each machine from which clients connect to the Manager. 4 Import the Manager’s certificate to the <ARCSIGHT_HOME>/jre/lib/security directory on all clients. See “Using Keytoolgui to Import a Certificate” on page 38. 5 Restart the Manager process so that the Manager can start using the self-signed certificate. Run the following command to do so: The self-signed certificate does not take effect until the Manager is restarted later in this procedure. This step overwrites your existing cacerts with the new one that contains the information about the Trusted Certificate Authority (CA) that signed your self-signed certificate. However, the new cacerts file does not take effect until the client is restarted later in this procedure. Make sure you have imported the Manager’s certificate to all existing clients before proceeding further. Otherwise, after you perform the next steps, only clients with the new Manager’s certificate can connect to the Manager.
2 Configuration Confidential Administrator’s Guide 47 /sbin/service arcsight_services restart manager 6 Restart all clients. 7 When installing a new client, repeat Steps 2-4 of this procedure. 8 On the ArcSight Web server, perform the steps listed in section “Setting up SSL Client Authentication on ArcSight Web” on page 62. 9 On the ArcSight Console, perform the steps listed in section “Setting up SSL Client-Side Authentication on ArcSight Console” on page 55. When clients communicate with multiple Managers To use self-signed certificate for a deployment in which clients communicate with more than one Managers, perform these steps for each Manager: 1 Follow Step 1 from the previous procedure on all Managers. 2 Copy the selfsigned.cer file from all Managers to the <ARCSIGHT_HOME>/jre/lib/security directory on one of your clients. To prevent a certificate file from overwriting another when you copy multiple certificate files with the same name to the same location, rename each certificate file as you copy. For example, copy the certificate file from ManagerA and rename it to SelfSigned_MgrA.cer. 3 On that client, use the keytoolgui utility to import certificates into the truststore (cacerts): a In <ARCSIGHT_HOME>/bin, run this command: ./arcsight keytoolgui b Click File->Open keystore. c In <ARCSIGHT_HOME>/jre/lib/security, select the store named cacerts. For the default password see “Cacerts password” on page 35. d Click Tools->Import Trusted Certificate: i Select the self-signed certificate for a Manager and click Import. ii You see the following message. Click OK. The Certificate details are displayed. Click OK. By following this procedure you append the self-signed certificate to the existing client truststore, cacerts. Doing so prevents overwriting cacerts, which happens if you follow the previous procedure.

Typically, the alias Name is same as the fully qualified host name. v You see the following message. Click OK. vi Save the truststore file. vii Repeat Steps i through vi for all self-signed certificates you copied. e On the client, enter this command in <ARCSIGHT_HOME>/bin to stop the client from using the currently in-use Demo certificate: ./arcsight tempca -rc For SmartConnectors, run: ./arcsight agent tempca –rc 4 Repeat this cacerts procedure on all other clients. 5 Restart the Manager service so that the Manager can start using the self-signed certificate. 6 Restart the client. 7 When installing a new client, copy the cacerts file from any client you updated earlier in this procedure. Using a CA-Signed SSL Certificate Using certificate signed by a Certificate Authority means replacing your demo or self-signed certificate. You should obtain two CA-signed certificates—one for the Manager and the other for ArcSight Web, unless both components are installed on the same machine. Follow the procedure described in this section to obtain and import the certificates to the Manager, and if appropriate, to ArcSight Web.
2 Configuration Confidential Administrator’s Guide 49 For information about managing certificates on a Connector Management container, refer to the Connector Management User’s Guide. Obtaining and deploying a CA-signed certificate involves these steps: 1 Create a Key Pair for a CA-Signed Certificate. 2 Send for the CA-Signed Certificate. 3 Import the CA Root Certificate. 4 Import the CA-Signed Certificate. 5 Restart the Manager. 6 Accommodating Additional Components. Create a Key Pair for a CA-Signed Certificate To Create a key pair: 1 On the Manager machine, run this command to launch the keytoolgui utility in <ARCSIGHT_HOME>/bin: ./arcsight keytoolgui 2 Click File->New keystore to create a new keystore. 3 Select JKS for the keystore Type, it supports Java keystore: 4 Click Tools->Generate Key Pair to create the key pair. This can take some time. 5 Enter key pair information such as the length of time for its validity (in days). Click OK. For Common Name (CN), enter the fully qualified domain name of the Manager. Ensure that DNS servers, used by the clients connecting to this host, can resolve this host name. For Email(E), provide a valid e-mail address as the CAs typically send an e-mail to this address to renew the certificate. When you click OK it asks you for a new password. Use the password of your existing keystore to save this keystore. Also, the Manager may fail to start if the password of the Key pair does not match the password of the keystore, which is encrypted in server.properties. If you do not remember the password, run the Manager setup Wizard and change the password of your existing keystore before you proceed. You reuse this file after receiving the reply from the CA. 6 Specify an alias name of mykey for referring to the new key pair.
2 Configuration 50 Administrator’s Guide Confidential 7 Click File->Save as and save the keystore with a name such as keystore.request. For ArcSight Web, save the file with a name such as webkeystore.request. Send for the CA-Signed Certificate To send for the CA-signed certificate, first create a certificate signing request (CSR). 1 In the keytoolgui utility, right-click the mykey alias name and select Generate CSR to create a Certificate Signing Request. 2 Choose a path and filename, and click Generate. After you enter a file name, the CSR file is generated in the current working directory. 3 Send the CSR to the selected Certificate Authority (CA). After verifying the information you send, the CA electronically signs the certificate using its private key and replies with a certification response that contains the signed certificate. Import the CA Root Certificate When you get the response from the certificate authority, it should include instructions for getting the root CA certificate. You can skip this step if renewing a CA-signed certificate issued by the same root certificate authority. You import the CA root certificate into the truststore file. 1 Save the Root CA certificate as a file rootca.cer. 2 Repeat the following procedure on all the machines where the Manager is installed: a Launch the keytoolgui utility on the Manager machine. b Click File > Open keystore. c Select the Truststore file located at <ARCSIGHT_HOME>/jre/lib/security/cacerts. Use the default password to open cacerts. For the default password see “Cacerts password” on page 35. d Click Tools >Import Trusted Certificate, and pick the rootca.cer file. e You see the following warning message: “Could not establish a trust path for the certificate. The certificate information will now be displayed after which you may confirm whether or not you trust the certificate.” f Click OK to finish. • If the CA root certificate has a chain, follow the same procedure to import all intermediate CA certificates into the Truststore. • Update the CA root certificate on other ArcSight Express components, as well. - Repeat step 2 on one of Consoles. - Copy the updated cacerts to any Logger or Connector Appliance, and other PCs that have installed Consoles, Connectors, or ArcSight Web. • Restart all services after the new cacerts is copied.
2 Configuration Confidential Administrator’s Guide 51 Import the CA-Signed Certificate When the CA has processed your request, it sends you a file with the signed certificate. You import this certificate into the Manager’s keystore. The SSL certificate you receive from the Certificate Authority must be a 128-bit X.509 Version 3 certificate. The type of certificate is the same one that is used for common web servers. The signed certificate must be returned by the CA in base64 encoded format. It looks similar to this: -----BEGIN CERTIFICATE----- MIICjTCCAfagAwIBAgIDWnWvMA0GCSqGSIb3DQEBBAUAMIGHMQswCQYDVQQGEwJaQT EiMCAGA1UECBMZRk9SIFRFU1RJTkcgUFVSUE9TRVMgT05MWTEdMBsGA1UEChMUVGhh d3RlIENlcnRpZmljYXRpb24xFzAVBgNVBAsTDlRFU1QgVEVTVCBURVNUMRwwGgYDVQ QDExNUaGF3dGUgVGVzdCBDQSBSb290MB4XDTAyMDkyNzIzMzI0MVoXDTAyMTAxODIZ MzI0MVowaDELMAkGA1UEBhMCrVMxDTALBgNVBAgTBGJsYWgxDTALBgNVBAcTBGJsYW gxDTALBgNVBAoTBGJsYWgxDTALBgNVBAsTBGJsYWgxHTAbBgNVBAMTFHppZXIuc3Yu YXJjc2lnaHQuY29tMIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQCZRGnVfQwG1b +BgABd/p8UhsaNov5AjaagAoBmouJCwgW2vwN4JViC CSBkDpiqVF7K11Sx4ZVSXX4+VQ6k4gT5G0kDNvQeN05wWkzEMygMB+ZBnYqPA/XtWR ZtjxvH MoqS+JEqHruiMLITC6q0reUB/txby6+S9zNo/fUG1pkIcQIDAQABoyUwIzATBgNVHS UEDDAKBggrBgEFBQcDATAMBgNVHRMBAg8EAjAAMA0GCSqGSIb3DQEBBAUAA4GBAFY3 7E60+P4b3zTLnaG7EVM57GtkED6PwCIilB6ixjvNL4MNGRubPa8kyaZp5fEDoNUPQV QxnpABjzTalRfYgjNFJ6ltI6ZKjBO5kim9UBeCnKiNNzhIyDyFwbHXOPB/JaLIV+jG ugYNS7hf/ay0BXKlfueO07EgjhhB/mQFs2JB -----END CERTIFICATE----- Before proceeding, make sure the name of the issuer that signed your certificate exists as a Trusted CA in cacerts. (Use keytoolgui to check your cacerts.) Follow these steps to import the signed certificate: 1 If the returned file has the .CER or .CRT file extension, save it to the <ARCSIGHT_HOME>/config/jetty directory and skip to step 4. 2 Using any text editor, copy and paste the text string to a file. Include the line "----- BEGIN CERTIFICATE-----" and line "-----END CERTIFICATE-----", and make sure there are no extra spaces before or after the string. 3 Save it to a file named ca_reply.txt on the Manager in the <ARCSIGHT_HOME>/config/jetty directory. 4 On the Manager machine, run this command in <ARCSIGHT_HOME>/bin: ./arcsight keytoolgui 5 Click File->Open keystore and select the keystore (keystore.request or webkeystore.request) you saved in Step 7 in “Create a Key Pair for a CA-Signed Certificate” on page 49. Provide the password you used to save the keystore in that step. 6 Right-click the key pair you created at the beginning of the process and named mykey. 7 Select Import CA Reply from the menu. 8 Select the CA reply certificate file and click Import.
2 Configuration 52 Administrator’s Guide Confidential If the CA reply file contains a chain of certificates, the keytoolgui utility tries to match the reply’s root CA to an existing Trusted Certificate in your cacerts truststore. If this operation fails, the Certificate Details dialog appears for manual verification. Acknowledge the certificate by clicking OK and answering Yes to the subsequent challenge. Answer No if the certificate is not trustworthy for some reason. After the key pair you generated has been updated to reflect the content of the CA reply, the keystore named keystore.request contains both the private key and the signed certificate (in the alias mykey). 9 Select File > Save. The keystore is now ready for use by the Manager or ArcSight Web. 10 Make a backup of the existing keystore by renaming it: Rename <ARCSIGHT_HOME>/config/jetty/keystore to <ARCSIGHT_HOME>/config/jetty/keystore.old. If, for any reason, the new keystore does not work properly, you can revert back to the demo keystore by replacing keystore.old with the new keystore. For ArcSight Web, rename the file to webkeystore.old. 11 Copy <ARCSIGHT_HOME>/config/jetty/keystore.request to <ARCSIGHT_HOME>/config/jetty/keystore. For ArcSight Web, copy webkeystore.request to webkeystore. 12 For successful reconfiguration and Manager startup, enter the keystore passwords into the appropriate properties file. Enter the password into the webserver.properties file for ArcSight Web using the following command (all on one line): arcsight changepassword -f <ARCSIGHT_HOME>/config/webserver.properties -p server.privatekey.password Enter the password into the server.properties file for the Manager using the following command (all on one line): arcsight changepassword -f <ARCSIGHT_HOME>/config/server.properties -p server.privatekey.password After entering this command the system displays the previous password as asterisks and asks you to enter and then confirm your new password. These commands enter the password into the properties file in an encrypted format. 13 If your Manager clients trust the CA that signed your server certificate, go to “Restart the Manager” on page 53. Otherwise, perform these steps to update the client’s cacerts (truststore): a Obtain a root certificate from the CA that signed your server certificate and copy it to your client machine. b For one client, use the keytoolgui utility to import the certificate into the truststore (cacerts): Also perform these steps on the Manager to update the Manager’s cacerts so that Manager clients such as the archive utility can work.
2 Configuration Confidential Administrator’s Guide 53 i In <ARCSIGHT_HOME>/bin, run this command: ./arcsight keytoolgui ii Click File->Open keystore. iii Select the store named cacerts. Use the default password to open cacerts. For the default password see “Cacerts password” on page 35. iv Click Tools->Import Trusted Certificate and select the certificate you copied in Step 10a of this procedure. v You see the following message. Click OK. vi Enter an alias for the Trusted Certificate you just imported and click OK. vii Right-click the alias ca in the truststore and choose Delete from the menu. viii Save the keystore. c Copy the <ARCSIGHT_HOME>/jre/lib/security/cacerts file from the client in the previous step to all other clients. 14 If your ArcSight Web browser clients trust the CA that signed your ArcSight Web certificate, go to Restart the Manager. Otherwise, perform these steps: a Obtain a root certificate from the CA that signed your ArcSight Web certificate. b Import the certificate into your web browser. See your browser’s documentation for details. Restart the Manager When you restart the Manager, clients it cannot communicate with it until their keystores are populated with the new certificate. 1 Restart the Manager. The Manager may fail to start if the password of the Key pair does not match the password of the keystore, which is encrypted in server.properties. If you do not remember the keystore password, run the Manager setup wizard and change the password of your existing keystore. 2 Restart all clients.
2 Configuration 54 Administrator’s Guide Confidential 3 To verify that the new certificate is in use: a From the command line navigate to <ARCSIGHT_HOME> and enter the command: arcsight tempca -i The output shows which CA issuer signed the SSL CA-signed certificate, certificate type, status of a validation of the certificate, and so on. b Point a web browser to https://<manager_hostname>:8443. to test it. Accommodating Additional Components Perform these extra steps to use CA-signed certificates with additional ArcSight Express components such as ArcSight Web, the ArcSight Console, or SmartConnectors.  Adding additional Managers You do not need to add the CA root certificate to the Truststore-cacerts file again. However, you must copy the cacerts file from the existing Manager to the new Manager.  Other ArcSight Components (Console, ArcSight Web, and SmartConnectors). When installing a new Console, you must copy the 'cacerts' file from the existing Console, which has been updated in the Phase 3, to the newly installed Console. This configuration procedure of Manager Ca-signed SSL certificate can be applied on the ArcSight Web server unless both components are installed on the same machine. For ArcSight Web, use the webserversetup utility after the certificate is updated to confirm the certificate is valid, as follows: a Login as an ArcSight Express user on the ArcSight Web server machine. b Execute the following command from <ARCSIGHT_HOME>/bin: ./arcsight webserversetup c Restart the ArcSight Web server. Removing a Demo Certificate You can remove the demo certificate by using the tempca script located in <ARCSIGHT_HOME>/bin. Issue the following command on all Manager and Console installations: arcsight tempca -rc For SmartConnectors, run the tempca script using the following command: arcsight agent tempca -rc Replacing an Expired Certificate When a certificate in your truststore/cacerts expires, you need to replace it with a new one. To replace the certificate: 1 Delete the expired certificate from the truststore/cacerts. To delete a certificate from the truststore or cacerts, start the keytoolgui and navigate to the certificate, right-click on the certificate, and select Delete. 2 Replace the certificate by importing the new certificate into truststore/cacerts as the case may be. Use the keytoolgui to import the new certificate into the truststore or
2 Configuration Confidential Administrator’s Guide 55 cacerts. See “ArcSight WebUsing a Self-Signed Certificate” on page 44, or “Using a CA- Signed SSL Certificate” on page 48 section (depending on the type of certificate you are importing) for steps on how to import the certificate. Since the common name (CN) for the new certificate is identical to the CN in the old certificate, you are not permitted to have both the expired as well as the new certificate co- exist in the truststore, cacerts. Establishing SSL Client Authentication By default, clients (SmartConnectors, Consoles, and ArcSight Web) authenticate using user name and password. The clients can optionally use SSL authentication for clients. If SSL client authentication is enabled, you can optionally disable user name and password login, as described in the next section. When client-side authentication is used, the SSL clients contain a keystore and the SSL server contains a truststore. For information about managing certificates for SmartConnectors, see the Connector Management User’s Guide. Setting up SSL Client-Side Authentication on ArcSight Console To enable client-side authentication for ArcSight Console running in default mode, perform these steps in addition to the ones you perform for setting up server authentication: 1 On each Console, generate a key pair. For CA-signed certificate follow the steps in section “Create a Key Pair for a CA-Signed Certificate” on page 49.: a From the Console’s <ARCSIGHT_HOME>/bin directory start the keytoolgui by running the following command: ./arcsight keytoolgui b Open File->New keystore. This opens the New keystore Type dialog. c Select JKS and click OK. d Click Tools->Generate Key Pair and fill in the fields in the following dialog: Before you enable client-side authentication, make sure that you log in to the Console and create a new user or modify an existing user such that you set the user’s external_id to the one specified in the certificate created on the Console. The external id should be set to the users name set as the CN (Common Name) setting when creating the certificate. The Common Name field in the following screen should be the external ID of the user logging in to the Manager that this console connects to.
2 Configuration 56 Administrator’s Guide Confidential e Enter an alias for the key pair in the following dialog and click OK: f Enter a password for the keystore and confirm it and click OK. g You see the following message. 2 Export the key pair you just generated. If you plan to install the Console, Manager, and Web on the same machine, make sure that this alias is unique. Also, do not use the machine name or IP address for the alias. ArcSight Web and Console cannot have identical CNs when installed on the same machine as the Manager. When you install ArcSight Web, set the CN of the ArcSight Web’s key pair you generate to the name or IP address of the machine on which you are installing it. Hence, if both Web and Console are on the same machine, and if you use the machine name or IP address for the CN for both the Web and the Console, then ArcSight Web gives you an error when configuring.
2 Configuration Confidential Administrator’s Guide 57 a In the keytoolgui right-click the key pair you just generated and select Export. b Make sure to select Head Certificate as Export Type and DER Encoded as the Export Format in the following dialog and click OK: c Enter a name for the certificate and click Export.
2 Configuration 58 Administrator’s Guide Confidential d You see the following message: e If your Console is on a different machine than the Manager, copy this certificate to the Manager’s machine. 3 If you are using self-signed certificate skip this step and continue with step 4.

You should now see a key pair with the alias you set for it in the keystore. 3 Create a client SSL configuration text file in the user/agent directory and name it agent.properties for a connector. The contents of this file (whether client or agent) should be as follows: auth.null=true ssl.client.auth=true cac.login.on=false ssl.keystore.path=config/arcsightkeystore.client ssl.keystore.password=<client.keystore_password> 4 Export the client’s (Connector) certificate using keytoolgui. See section “Using Keytoolgui to Export a Certificate” on page 37 for details. 5 Import the CA’s certificate of the client’s certificate (in case you are using CA-signed certificate) or the client’s certificate itself (in case you are using a self-signed certificate) into the Manager’s truststore, /config/jetty/truststore. see section “Using Keytoolgui to Import a Certificate” on page 38 for details. 6 Restart the Manager. 7 Restart the client (Connector). For information about restarting a SmartConnector’s container, see the Connector Management User’s Guide. Migrating from one certificate type to another When you migrate from one certificate type to another on the Manager, you have to update all Consoles, SmartConnectors, and ArcSight Web installations. For information about managing certificates for SmartConnectors, see the Connector Management User’s Guide. Migrating from Demo to Self-Signed To migrate from a demo to self-signed certificate: 1 Follow the steps described in “ArcSight WebUsing a Self-Signed Certificate” on page 44. 2 Follow the instructions in “Verifying SSL Certificate Use” on page 70 to ensure that a self-signed certificate is in use. Make sure that this password is identical to the password that you set for /config/keystore.client when creating it.
2 Configuration 70 Administrator’s Guide Confidential Migrating from Demo to CA-Signed To migrate from a demo to CA-Signed certificate: 1 Follow the steps described in “Using a CA-Signed SSL Certificate” on page 48. 2 Follow the instructions in “Verifying SSL Certificate Use” on page 70 to ensure that CA- signed certificate is in use. Migrating from Self-Signed to CA-Signed To migrate from a self-signed to CA-signed certificate: 1 Follow the steps described in “Using a CA-Signed SSL Certificate” on page 48. 2 Follow the instructions in “Verifying SSL Certificate Use” on page 70 to ensure that a CA-signed certificate is in use. Verifying SSL Certificate Use After the migration, run this command in <ARCSIGHT_HOME>/bin on the client to ensure the certificate type you intended is in use: ./arcsight tempca –i In the resulting output, a sample of which is available below, do the following: 1 Review the value of the line: Demo CA trusted. The value should be “no.” If the value is “yes,” the demo certificate is still in use. Follow these steps to stop using the demo certificate: a In <ARCSIGHT_HOME>/bin, enter the following command to make the client stop using the currently in use demo certificate: ./arcsight tempca -rc For SmartConnectors, run: ./arcsight agent tempca –rc b Restart the client. 2 Verify that the Certificate Authority that signed your certificate is listed in the output.

Using Certificates to Authenticate Users to ArcSight Instead of using a user name and password to authenticate a user to the Manager or ArcSight Web, you can configure these systems to use a digitally-signed user certificate. This section tells you how to do that. You can use Manager’s this capability in environments that make use of Public Key Infrastructure (PKI) for user authentication. The Manager and ArcSight Web accept login calls with empty passwords and use the Subject CN (Common Name) from the user’s certificate to identify the user. You must enable SSL client authentication as described in the previous section to use digitally-signed user certificates for user authentication. To configure the Manager or ArcSight Web to use user certificates, do the following: 1 On the Console, make sure that External ID field in the User Editor for every user is set to a value that matches the CN in their user certificate. 2 Restart the system you are configuring. 3 Restart the Consoles. When you start the Console, the user name and password fields are grayed out. Simply select the Manager to which you want to connect and click OK to log in. Using the Certificate Revocation List (CRL) ArcSight Express supports the use of CRL to revoke a CA-signed certificate that has been invalidated. The CA that issued the certificates also issues a CRL file containing a signed list of certificates that it had previously issued, and that it now considers invalid. The Manager checks the client certificates against the list of certificates listed in the CRL and denies access to clients whose certificates appear in the CRL. Before you use the CRL feature, make sure:  Your certificates are issued/signed by a valid Certificate Authority or an authority with an ability to revoke certificates.  The CA’s root certificate is present in the Manager’s <ARCSIGHT_HOME>/config/jetty/truststore directory. The Manager validates the authenticity of the client certificate using the root certificate of the signing CA.  You have a current CRL file provided by your CA. Before you enable client-side authentication, make sure that you log in to the Console and create a new user or modify an existing user such that you set the user’s external_id to the one specified in the certificate created on the Console. The external id should be set to the users name set as the CN (Common Name) setting when creating the certificate.
2 Configuration 72 Administrator’s Guide Confidential The CA updates the CRL file periodically as and when additional certificates get invalidated. To use the CRL feature: 1 Make sure you are logged out of the Console. 2 Copy the CA-provided CRL file into your Manager’s <ARCSIGHT_HOME>/config/jetty/crls directory. After adding the CRL file, it takes approximately a minute for the Manager to get updated. Reconfiguring the ArcSight Console after Installation You can reconfigure ArcSight Console at anytime by typing arcsight consolesetup within a command prompt window. Run the ArcSight Console Configuration Wizard by entering the following command in a command window in the <ARCSIGHT_HOME>/bin directory: ./arcsight consolesetup To run the ArcSight Console Setup program without the graphical user interface, type: ./arcsight consolesetup -i console The ArcSight Console Configuration Wizard appears. Reconfiguring Connectors Use the Connector Management module of the Management Console to reconfigure connectors that it manages. For information, see the Connector Management User’s Guide. For information about reconfiguring SmartConnectors on remote hosts and not managed by the Connector Management feature, refer to each SmartConnector’s SmartConnector Configuration Guide, and the SmartConnector User’s Guide. Reconfiguring ArcSight Manager To reconfigure Manager settings made during installation, run the Manager Configuration Wizard by typing the following command in a terminal box or command prompt window: ./arcsight managersetup The arcsight managersetup command opens the Manager Configuration Wizard, but you can also run the Manager Setup program silently by typing: ./arcsight managersetup -i console The Manager Configuration Wizard appears to help you re-configure the Manager. The managersetup wizard is covered in “Running the Manager Configuration Wizard” on page 91.
2 Configuration Confidential Administrator’s Guide 73 To change advanced configuration settings (port numbers, database settings, log location, and so on) after the initial installation, change the server.properties file. ArcSight’s default settings are listed in the server.defaults.properties file. You can override these default settings by adding the applicable lines from server.defaults.properties to the server.properties file. These files are located in <ARCSIGHT_HOME>/config. Changing ArcSight Manager Ports In order for every component of ArcSight to communicate, any ArcSight SmartConnectors and ArcSight Consoles must be aware of what IP address the Manager is running on. Also, the ArcSight SmartConnectors and ArcSight Consoles must use the same HTTP or HTTPS port numbers the Manager is currently using. The Manager uses a single port (by default, 8443) that any firewalls between the Manager, ArcSight Console, and any ArcSight SmartConnectors must allow communication through. Port 8443 is the default port used when initially installing ArcSight, however, you can change this default port number using the Manager Configuration Wizard. Changing ArcSight Web Session Timeouts The session timeout affects the web browser pages (i.e., Knowledge Base, reports, and so forth) that appear within ArcSight Web. After the session has elapsed, or timed out, you must log back into ArcSight Web to start a new session. You can change the Web default session timeout in this file in the Manager’s <ARCSIGHT_HOME>/config/jetty/server.xml file. The ArcSight Web default session timeout can be changed in this file in ArcSight Web’s <ARCSIGHT_HOME>/config/jetty/webserver.xml file. In the above .xml files you see the following lines: <session-config> <session-timeout>15</session-timeout> </session-config> The value specified, in this case 15, is the session timeout in minutes. Simply change this number to the session timeout desired and save the file. Managing Password Configuration The Manager supports a rich set of functionality for managing users passwords. This section describes various password configuration options. Generally, all the settings are made by editing the server.properties file. See “Managing and Changing Properties File Settings” on page 15. Some of these control character restrictions in passwords. Enforcing Good Password Selection There are a number of checks that the Manager performs when a user picks a new password in order to enforce good password selection practices.
2 Configuration 74 Administrator’s Guide Confidential Password Length The simplest one is a minimum and, optionally, a maximum length of the password. The following keys in server.properties affect this: auth.password.length.min=6 auth.password.length.max=20 By default, the minimum length for passwords is six characters and the maximum length is 20 characters and can contain numbers and/or letters. Configuring the above properties to a value of -1 sets the password length to unlimited characters. Restricting Passwords Containing User Name Another mechanism that enforces good password practices is controlled through the following server.properties key: auth.password.userid.allowed=false When this key is set to false (the default), a user cannot include their user name as part of the password. Password Character Sets For appliance users, the Manager comes installed using the UTF-8 character set. If you install the Manager, it allows you to set the character set encoding that the Manager uses. When you install the ArcSight Console, the operating system on that machine controls the character set the Console uses. Be sure the operating system uses the same character set as the Manager if:  A user password contains "non-English" characters (in the upper range of the character set: values above 127)  That user wants to log in with that ArcSight Console. This is not an issue if you log in from the web-based Management Console or ArcSight Web. For passwords that are in the ASCII range (values up to 127), the character set for the ArcSight Console does not matter. Requiring Mix of Characters in Passwords Good passwords consist not only of letters, but contain numbers and special characters as well. This makes them a lot harder to guess and, for the most part, prevents dictionary attacks. By default, the minimum length for passwords is six characters and the maximum length is 20 characters and can contain numbers and/or letters. The following properties control the distribution of characters allowed in new passwords: auth.password.letters.min=-1 auth.password.letters.max=-1
2 Configuration Confidential Administrator’s Guide 75 auth.password.numbers.min=-1 auth.password.numbers.max=-1 auth.password.whitespace.min=0 auth.password.whitespace.max=0 auth.password.others.min=-1 auth.password.others.max=-1 The *.min settings can be used to enforce that each new password contains a minimum number of characters of the specified type. The *.max settings can be used to limit the number of characters of the given type that new passwords can contain. Letters are all letters from A-Z, upper and lowercase, numbers are 0-9; “whitespace” includes spaces, etc.; “others” are all other characters, including special characters such as #$%@!. Additionally, the following server.properties key lets you restrict the number of consecutive same characters allowed. auth.password.maxconsecutive=3 For example, the default setting of 3 would allow "adam999", but not "adam9999" as a password. Furthermore, the following server.properties key enables you to specify the length of a substring that is allowed from the old password in the new password. auth.password.maxoldsubstring=-1 For example, if the value is set to 3 and the old password is “secret”, neither “secretive” nor “cretin” is allowed as a new password. Checking Passwords with Regular Expressions To accommodate more complex password format requirements, the Manager can also be set up to check all new passwords against a regular expression. The following server.properties keys can be used for this purpose: auth.password.regex.match= auth.password.regex.reject= The auth.password.regex.match property describes a regular expression that all passwords have to match. If a new password does not match this expression, the Manager rejects it. The auth.password.regex.reject property describes a regular expression that no password may match. If a new password matches this regular expression, it is rejected. For more information on creating an expression for this property, see http://www.regular- expressions.info/. The following are a few examples of regular expressions and a description of what they mean.  auth.password.regex.match= /^D.*D$/ Backslash ( ) characters in regular expressions must be duplicated (escaped)—instead of specifying , type .
2 Configuration 76 Administrator’s Guide Confidential Only passwords that do not start or end with a digit are accepted.  auth.password.regex.match= ^(?=.*[A-Z].*[A-Z])(?=.*[a-z].*[a- z])(?=.*[0-9].*[0-9])(?=.*[^a-zA-Z0-9].*[^a-zA-Z0-9]).{10,}$ Only passwords that contain at least 10 characters with the following breakdown are accepted:  At least two upper case letters  At least two lower case letters  At least two digits  At least two special characters (no digits or letters)  auth.password.regex.reject= ^(?=.*[A-Z].*[A-Z])(?=.*[a-z].*[a- z])(?=.*[0-9].*[0-9])(?=.*[^a-zA-Z0-9].*[^a-zA-Z0-9]).{12,}$ The passwords that contain 12 characters with the following breakdown are rejected:  At least two upper case letters  At least two lower case letters  At least two digits  At least two special characters (no digits or letters) Password Uniqueness In some environments, it is also desirable that no two users use the same password. To enable a check that ensures this, the following server.properties key can be used: auth.password.unique=false If set to true, the Manager checks all other passwords to make sure nobody is already using the same password. Setting Password Expiration The Manager can be set up to expire passwords after a certain number of days, forcing users to choose new passwords regularly. This option is controlled by the following key in server.properties: auth.password.age=60 By default, a password expires 60 days from the day it is set. When this setting is used, however, some problems arise for user accounts that are used for automated log in, such as the user accounts used for Manager Forwarding Connectors. These user accounts can be excluded from password expiration using the following key in server.properties: auth.password.age.exclude=username1,username2 This value is a comma-separated list of user names. The passwords of these users never expire. This feature may not be appropriate for some environments as it allows valid users of the system to guess other user’s passwords.
2 Configuration Confidential Administrator’s Guide 77 The Manager can also keep a history of a user’s passwords to make sure that passwords are not reused. The number of last passwords to keep is specified using the following key in server.properties: auth.password.different.min=1 By default, this key is set to check only the last password (value = 1). You can change this key to keep up to last 20 passwords. Restricting the Number of Failed Log Ins The Manager tracks the number of failed log in attempts to prevent brute force password guessing attacks. By default, a user's account is disabled after three failed log in attempts. This feature is controlled through the following key in server.properties: auth.failed.max=3 Change this to the desired number or to -1 if you do not wish user accounts to be disabled, regardless of the number of failed log in attempts. Once a user account has been disabled, the Manager can be configured to automatically re-enable it after a certain period of time. This reduces administrative overhead, while effectively preventing brute force attacks. This mechanism is controlled by the following key in server.properties: auth.auto.reenable.time=10 This value specifies the time, in minutes, after which user accounts are automatically re- enabled after they were disabled due to an excessive number of incorrect log ins. Set the property key to -1 to specify that user accounts can only be re-enabled manually. Re-Enabling User Accounts Under normal circumstances, user accounts that have been disabled—for example, as a result of too many consecutive failed log ins—can be re-enabled by any user with sufficient permission. Check the Login Enabled check box for a particular user in the User Inspect/Editor panel in the ArcSight Console. If the only remaining administrator user account is disabled, a command line tool can be run on the system where the Manager is installed to re-enable user accounts. First, ensure that the the Manager is running. Then, from the command line, run the following command: ./arcsight reenableuser username where username is the name of the user you want to re-enable. After this procedure, the user can log in again, using the unchanged password.
2 Configuration 78 Administrator’s Guide Confidential Advanced Configuration for Asset Auto-Creation Assets are automatically created for all components and, if applicable, for assets arriving from scan reports sent by vulnerability scanners via scanner SmartConnectors. This is done by the asset auto-creation feature. If the profile of events in your network causes asset auto creation feature to create assets in your network model inefficiently, you can modify the asset auto creation default settings in the user configuration file, server.properties. The server.properties file is located at $ARCSIGHT_HOME/config/server.properties. For more about working with properties files, see the topic “Managing and Changing Properties File Settings” Asset Auto-Creation from Scanners in Dynamic Zones The following properties relate to how assets are created from a vulnerability scan report for dynamic zones. Create Asset with either IP Address or Host Name By default, an asset is not created in a dynamic zone if there is no host name present. The property set by default is: scanner-event.dynamiczone.asset.nonidentifiable.create=false You can configure ArcSight Express to create the asset as long as it has either an IP address or a host name. In server.properties, change scanner- event.dynamiczone.asset.nonidentifiable.create from false to true. ArcSight Express discards conflicts between an IP address and host name (similar IP address, but different host name and/or MAC address). When this property is set to true, the following takes place: Creating an asset if no host name is present can result in an inaccurate asset model. Setting scanner-event.dynamiczone.asset.nonidentifiable.create to true means that assets are created if the asset has either an IP address or a host name. This could lead to disabled assets or duplicated assets being created. Change this configuration only if you are using a dynamic zone to host ostensibly static assets, such as long-lived DHCP addresses. Example Action taken if no conflicts Action taken if previous asset with similar information IP=1.1.1.1 hostname=myhost mac=0123456789AB Asset created Asset created, previous asset is deleted.
2 Configuration Confidential Administrator’s Guide 79 Preserve Previous Assets This setting applies when ArcSight Express creates assets from a vulnerability scan report for dynamic zones. By default, if a previous asset with similar information already exists in the asset model, ArcSight Express creates a new asset and deletes the old one. To preserve the previous asset rather than delete it when a scan finds a new asset with similar information, you can configure ArcSight Express to rename the previous asset. In server.properties, change scanner- event.dynamiczone.asset.ipconflict.preserve from false to true. When the system is configured with scanner- event.dynamiczone.asset.nonidentificable.create=false and scanner- ip=1.1.1.1 hostname=myhost mac=null Asset created Asset created, previous asset is deleted. ip=1.1.1.1 hostname=null mac=0123456789AB Asset created Asset created, previous asset is deleted. ip=1.1.1.1 hostname=null mac=null Asset created Asset created, previous asset is deleted. ip=null hostname=myhost mac=null Asset created Asset created, previous asset is deleted. ip=null hostname=null mac=0123456789AB Asset not created. Either host name or IP address is required. Asset not created. Either host name or IP address is required. ip=null hostname=myhost mac=0123456789AB Asset not created. Either host name or IP address is required. Asset not created. Either host name or IP address is required. Preserving previous assets results in a larger asset model. Setting event.dynamiczone.asset.ipconflict.preserve to true means that assets are continually added to the asset model and not removed. Use this option only if you know you must preserve all assets added to the asset model. Example Action taken if no conflicts Action taken if previous asset with similar information
2 Configuration 80 Administrator’s Guide Confidential event.dynamiczone.asset.ipconflict.preserve=true, it takes the following actions: Changing the Default Naming Scheme By default, the system names assets that come from scanners using the naming scheme outlined in the topic “Asset Names” in the ArcSight Console User’s Guide. You can reconfigure this naming scheme. For example, if you want the asset name for an asset in a static zone to appear this way in the ArcSight Console: myhost_1.1.1.1 Example Action taken if previous asset with similar information and preserve = true IP=1.1.1.1 hostname=myhost mac=0123456789AB Asset created, previous asset is renamed. ip=1.1.1.1 hostname=myhost mac=null Asset created, previous asset is renamed. ip=1.1.1.1 hostname=null mac=0123456789AB Asset created, previous asset is renamed. ip=1.1.1.1 hostname=null mac=null No action taken. Either host name or MAC address is required. ip=null hostname=myhost mac=null Asset created, previous asset is renamed. ip=null hostname=null mac=0123456789AB Asset created, previous asset is renamed. ip=null hostname='myhost' mac=0123456789AB Asset created, previous asset is renamed. Static Zone Dynamic Zone Property: scanner-event.auto- create.asset.name.template scanner-event.auto- create.dynamiczone.asset.name .template Value: $destinationAddress - $!destinationHostName $destinationHostName Example: 1.1.1.1 - myhost myhost
2 Configuration Confidential Administrator’s Guide 81 In this case, change the default $destinationAddress - $!destinationHostName to $!destinationHostName_$destinationAddress Compression and Turbo Modes Compressing SmartConnector Events ArcSight SmartConnectors can send event information to the Manager in a compressed format using HTTP compression. The compression technique used is standard GZip, providing compression ratio of 1:10 or higher, depending on the input data (in this case, the events the ArcSight SmartConnector is sending). Using compression lowers the overall network bandwidth used by ArcSight SmartConnectors dramatically, without impacting their overall performance. By default, all ArcSight SmartConnectors have compression enabled. To turn it off, add the following line to the <ARCSIGHT_HOME>/user/agent/agent.properties file: compression.enabled = false ArcSight SmartConnectors determine whether the Manager they are sending events to supports compression. Reducing Event Fields with Turbo Modes If your configuration, reporting, and analytic usage permits, you can accelerate the transfer of sensor information through SmartConnectors by choosing one of the "turbo" modes, which send fewer event fields from the connector. The default transfer mode is called Complete, which passes all the data arriving from the device, including any additional data (custom, or vendor-specific). ArcSight SmartConnectors can be configured to send more or less event data, on a per- SmartConnector basis, and the Manager can be set to read and maintain more or less event data, independent of the SmartConnector setting. Some events require more data than others. For example, operating system syslogs often capture a considerable amount of environmental data that may or may not be relevant to a particular security event. Firewalls, on the other hand, typically report only basic information. ArcSight Express defines the following Turbo Modes: When Turbo Mode is not specified (mode 3, Complete), all event data arriving at the SmartConnector, including additional data, is maintained. (Versions of ArcSight prior to 3.2 ran in Turbo Mode 3.) Turbo Mode 2, Faster, eliminates the additional custom or vendor- specific data, which is not required in many situations. Turbo Mode 1, Fastest, eliminates all but a core set of event attributes, in order to achieve the best throughput. Because the Turbo Modes 1 Fastest Recommended for firewalls 2 Faster Manager default
2 Configuration 82 Administrator’s Guide Confidential event data is smaller, it requires less storage space and provides the best performance. It is ideal for simpler devices such as firewalls. The Manager processes event data using its own Turbo Mode setting. If SmartConnectors report more event data than the Manager needs, the Manager ignores the extra fields. On the other hand, if the Manager is set to a higher Turbo Mode than a SmartConnector, the Manager maintains fields that are not filled by event data. Both situations are normal in real-world scenarios, because the Manager configuration reflects the requirements of a diverse set of SmartConnectors. Event data transfer modes are numbered (1 for Fastest, 2 for Faster, 3 for Complete), and possible Manager-SmartConnector configurations are therefore: 1-1 Manager and SmartConnector in Fastest mode 1-2 SmartConnector sending more sensor data than Manager needs 1-3 SmartConnector sending more sensor data than Manager needs 2-1 SmartConnector not sending all data that Manager is storing* 2-2 Manager and SmartConnector in Faster mode 2-3 Default: Manager does not process additional data sent by SmartConnector 3-1 Manager maintains Complete data, SmartConnector sends minimum* 3-2 Manager maintains additional data, but SmartConnector does not send it 3-3 Manager and SmartConnector in Complete mode *When the SmartConnector sends minimal data (Turbo Mode 1), the Manager can infer some additional data, creating a 2-1.5 or a 3-1.5 situation. 3 Sending Events as SNMP Traps ArcSight Express can send a sub-stream of all incoming events (that includes rule- generated events) via SNMP to a specified target. A filter is used to configure which events are sent. ArcSight Express’s correlation capabilities can be used to synthesize network management events that can then be routed to your enterprise network Management Console. Configuration of the SNMP trap sender The SNMP trap sender is configured using the Manager configuration file. The <ARCSIGHT_HOME>/config/server.default.properties file includes a template for the required configuration values. Copy those lines into your <ARCSIGHT_HOME>/config/server.properties file and make the changes there. After making changes to this file, you need to restart the Manager. Setting the Manager to send SNMP v3 traps is not FIPS compliant. This is because SNMP v3 uses the MD5 algorithm. However, SNMPv1 and v2 are compliant.
2 Configuration Confidential Administrator’s Guide 83 properties: The following provides a description of specific SNMP configuration parameters: snmp.trapsender.enabled=true Set this property to true in order to enable the SNMP trap sender. snmp.trapsender.uri= /All Filters/Arcsight System/SNMP Forwarding/SNMP Trap Sender The filter (specified by URI, all on one line) is used to decide whether or not an event is forwarded. There is no need to change the URI to another filter, as the "SNMP Trap Sender" filter can be changed through the ArcSight Console. Changes to the filter specified immediately affect the SNMP trap sender. By default, the "SNMP Trap Sender" filter logic is Matches Filter (Correlated Events)—that is, only rules-generated events are forwarded. snmp.destination.host= snmp.destination.port=162 The host name and the port of the SNMP listener that wants to receive the traps. snmp.read.community=public snmp.write.community=public The SNMP community strings needed for the traps to make it through to the receiver. The read community is reserved for future use, however, the write community must match the community of the receiving host. This depends on your deployment environment and your receiving device. Please consult your receiving device's documentation to find out which community string to use. snmp.version=1 snmp.fields= event.eventId, event.name, event.eventCategory, event.eventType, event.baseEventCount, event.arcsightCategory, event.arcsightSeverity, event.protocol, event.sourceAddress, event.targetAddress These event attributes should be included in the trap. The syntax follows the SmartConnector SDK as described in the FlexConnector Developer’s Guide. All the ArcSight
2 Configuration 84 Administrator’s Guide Confidential fields can be sent. The identifiers are case sensitive, do not contain spaces and must be capitalized except for the first character. For example: The SNMP field types are converted as: Additional data values are accessible by name, for example: snmp.fields=event.eventName,additionaldata.myvalue This sends the Event Name field and the value of myvalue in the additional data list part of the SNMP trap. Only the String data type is supported for additional data, therefore all additional data values are sent as OCTET STRING. Asset Aging The age of an asset is defined as the number of days since it was last scanned or modified. So, for example, if an asset was last modified 29 hours ago, the age of the asset is taken as 1 day and the remaining time (5 hours, in our example) is ignored in the calculation of the asset’s age. You can use asset aging to reduce asset confidence level as the time since the last scan increases. Excluding Assets From Aging To exclude certain assets from aging, you can add those assets to a group and then set the property asset.aging.excluded.groups.uris in the server.properties file to the URI(s) of those groups. For example, to add the groups MyAssets and DontTouchThis (both under All Assets) add the following to the server.properties file: #Exclude MyAssets and DontTouchThis from aging asset.aging.excluded.groups.uris=/All Assets/MyAssets,/All Assets/DontTouchThis ArcSight Field SDK/SNMP trap sender identifier Event Name eventName Device Severity deviceSeverity Service service ArcSight SNMP STRING OCTET STRING INTEGER INTEGER32 Address IP ADDRESS LONG OCTET STRING BYTE INTEGER When setting the asset.aging.excluded.groups.uris property keep in mind that the assets in this group are not disabled, deleted or amortized.
2 Configuration Confidential Administrator’s Guide 85 Task to Disable Assets of a Certain Age By default, asset aging is disabled. There is a new scheduled task that disables any scanned asset that has reached the specified age. By default, once the assets aging feature is turned on this task runs every day half an hour after midnight (00:30:00). Add the following in the server.properties file to define asset aging: #----------------------------- # Asset aging #----------------------------- # Defines how many days can pass before a scanned asset is defined as old # after this time the asset will be disabled # Default value: disabled asset.aging.daysbeforedisable = -1 To Delete an Asset To delete the asset instead of disabling it, you have to set the property asset.aging.task.operation to delete in server.properties file: # Delete assets when they age asset.aging.task.operation = delete Amortize Model confidence with scanned asset age The IsScannedForOpenPorts and IsScannedForVulnerabilities sub-elements in the ModelConfidence element are factored by the age of an asset. They are extended to include an optional attribute, AmortizeScan. If AmortizeScan is not defined (or defined with value -1), the assets are not amortized. A "new" asset gets the full value while and "old" asset gets no points. You can edit the AmortizeScan value (number of days) in the Manager’s /config/server/ThreatLevelFormula.xml file: <ModelConfidence> <Sum MaxValue="10" Weight="10"> <!-- If target Asset is unknown, clamp modelConfidence to 0 - -> <HasValue FIELD="targetAssetId" Value="-10" Negated="Yes" /> <HasValue FIELD="targetAssetId" Value="4" Negated="NO" /> <!-- Give 4 points each for whether the target asset has been scanned for open ports and vulnerabilities --> <!-- This values can be amortized by the age of the asset --> <!-- that means that the value will reduce constantly over time as the asset age --> <!-- ie if you set the value to be 120 on the day the assets are created they receive the four points, by day 60 they'll receive 2 points and by day 120 they'll receive 0 points --> <IsScannedForOpenPorts Value="4" Negated="NO" AmortizeScan="-1" /> <IsScannedForVulnerabilities Value="4" Negated="NO" AmortizeScan="-1" /> </Sum> </ModelConfidence>
2 Configuration 86 Administrator’s Guide Confidential For this example, the value is modified as follows: Configuring Actors Configuring the Actors feature requires a one-time setup procedure and minimal maintenance if authentication systems are added, modified, or removed from your network. This setup procedure maps the user authentication systems you use in your network environment and the account IDs for each user on those systems. 1 Install the Actor Model Import connector appropriate for your IDM. For complete instructions about how to install the connector, see the relevant SmartConnector installation and configuration guide, such as the SmartConnector Configuration Guide for Microsoft Active Directory Actor Model. Once installed, the connector polls the IDM and imports the user data into the Actor model. 2 Identify the authenticators in your environment. In preparation for configuring the authenticator mapping table, open the dashboard for automatically identifying the user authentication data stores running in your environment and their type: /All Dashboards/ArcSight Administration/ESM/Configuration Changes/Actors/Actor Administration This dashboard is populated by the following query viewer, which looks for events with a value in the Authenticator field: /All Query Viewers/ArcSight Administration/ESM/Configuration Changes/Actor/Actor Authenticators The example below shows the value of the Attributes field for an active directory system configured as Active Directory:<domain>.com. Use this exact value, including punctuation, spaces, and capitalization, to populate the account authenticators mapping table described in the next step. 3 Configure the Authenticators mapping table.

Supporting 50,000 actors requires an additional 2 GB of Java heap memory in the Manager. An additional 300 MB is needed for each category model you construct that uses 50,000 actors. This additional memory is not in use all the time, but is needed for certain operations. For instructions about how to run the managersetup utility, see the Administrator’s Guide. Column Description Device Vendor The vendor that supplies the authentication data store, such as Microsoft. Device Product Provide the application name of the authentication system, such as Active Directory. Agent Address The IP address of the reporting SmartConnector. Agent Zone Resource The zone in which the reporting SmartConnector resides.

For details about starting and stopping the Manager, see “Basic Administration Tasks” in the Administrator’s Guide For details about working with the server.properties file, see “Managing and Changing Properties File Settings” in the Administrator’s Guide. Permissions Required to Use Actor-Related Data By default, Admin users have full read/write access to the actors feature and the other resources that actors depend on. The Admin can grant permissions for actors and the other resources upon which the actors feature depends to other users. To create actors, actor channels, and category models:  Read and write on /All Actors  Read and write on /All Session Lists/ArcSight System/Actor Data and /All Session Lists/ArcSight System/Actor Data Support  Read on /All Field Sets/ArcSight System/Actor Field Sets/Actor Base  Read on the filters used to define the event ACLS for that user group, for example, All Filters/ArcSight System/Core  Read and write on the group in which the new resource is being created To view actors and category models, and monitor actor channels:  Read on /All actors  Read on /All Session Lists/ArcSight System/Actor Data and /All Session Lists/ArcSight System/Actor Data Support  Read on /All Field Sets/ArcSight System/Actor Field Sets/Actor Base To use actor global variables provided in standard content rules, active channels, and reports that leverage actor data: Read access on the following resources and groups:  /All Fields/ArcSight System/Actor Variables (either directly, or inherited from /All Fields/ArcSight System)  /All Actors  /All Session Lists/ArcSight System  /All Active Lists/ArcSight System/Actor Data Support (for the authenticator active list)  /All Filters/ArcSight Foundation  The appropriate group that gives all the queries used by a query viewer that leverages actor data  The appropriate group that contains a query viewer that leverages actor data  The appropriate group(s) for the filters used by any queries and query viewers that leverage actor data
2 Configuration Confidential Administrator’s Guide 89 In addition to these permissions on the actor-related resources themselves, read permissions are needed for any resources (such as filters, user-created actor global variables, and so on) upon which these actor-related resources rely. For details about how to assign permissions to user groups, see “Granting or Removing Resource Permissions” on page 604. About Exporting Actors If you need to export your entire actor model to image another Manager, you can do it using the export_system_tables command-line utility using the -s parameter, the parameter used to specify export of session list data. The -s parameter captures the special session list infrastructure that is part of the Actor Resource Framework in addition to the actor resources themselves. For instructions about how to use the export_system_tables command-line utility, see the Administrator’s Guide. Best practice: Log out and log back in again for permission changes to take effect As a best practice whenever an admin changes another user’s permissions, the other user should log out and log back in again. This ensures that the new permissions are registered with the Manager, and the user can see the changes.

The Java Heap memory size is the amount of memory that ArcSight Express allocates for its heap. (Besides the heap memory, the Manager also uses some additional system memory.) 5 The Manager controls SSL certificate type for communications with the Console, so the wizard prompts you to select the type of SSL certificate that the Manager is using. If you changed the Manager host name in Step 2 on page 92, select Replace with new Self-Signed key pair, otherwise select Do not change anything. If you selected Replace with new Self-Signed key pair, you are prompted to enter the password for the SSL key store and then details about the new SSL certificate to be issued.

3 Running the Manager Configuration Wizard Confidential Administrator’s Guide 97 Authentication Details The authentication options enable you to select the type of authentication to use when logging into the Manager. By default, the system uses its own, built-in authentication, but you can specify third party, external authentication mechanisms, such as RADIUS Authentication, Microsoft Active Directory, LDAP, or a custom JAAS plug-in configuration. How external authentication works The Manager uses the external authentication mechanism for authentication only, and not for authorization or access control. That is, the external authenticator only validates the information that users enter when they connect to the Manager by doing these checks:  The password entered for a user name is valid.  If groups are applicable to the mechanism in use, the user name is present in the groups that are allowed to access ArcSight Manager. Users who pass these checks are authenticated. Once you select an external authentication mechanism, all user accounts, including the admin account, are authenticated through it. Guidelines for setting up external authentication Follow these guidelines when setting up an external authentication mechanism:  Users connecting to the Manager must exist on the Manager.  User accounts, including admin, must map to accounts on the external authenticator. If the accounts do not map literally, you must configure internal to external ID mappings in the Manager.  Users do not need to be configured in groups on the Manager even if they are configured in groups on the external authenticator.  If user groups are configured on the Manager, they do not need to map to the group structure configured on the external authenticator.  Information entered to set up external authentication is not case sensitive. • In order to use PKCS#11 authentication, you must select one of the SSL based authentication methods. • If you plan to use PKCS #11 token with ArcSight Web, make sure to select Password Based or SSL Client Based Authentication. • PKCS#11 authentication is not supported with Radius, LDAP and Active Directory authentication methods. See the appendix “Using the PKCS#11 Token‚” in the ArcSight Express Configuration Guide, for details on using a PKCS #11 token such as the Common Access Card (CAC).
3 Running the Manager Configuration Wizard 98 Administrator’s Guide Confidential  To restrict information users can access, set up Access Control Lists (ACLs) on the Manager. Password Based Authentication Password-based authentication requires users to enter their User ID and Password when logging in. You can select the built-in authentication or external authentication. Built-In Authentication This is the default authentication when you do not specify a third party external authentication method. If you selected this option, you are done. Setting up RADIUS Authentication To configure ArcSight Manager for RADIUS Authentication, choose RADIUS Authentication and supply the following parameter values: If you configure the Manager using Password Based and SSL Client Based Authentication or SSL Client Only Authentication, be aware that ArcSight Web does not support these modes. So: • If you plan to use ArcSight Web, you will need to configure your Manager to use Password Based Authentication or Password Based or SSL Client Based Authentication as your authentication method. • If you plan to use PKCS#11 authentication with ArcSight Web, be sure to select Password Based or SSL Client Based Authentication only. Parameter Description Authentication Protocol Which authentication protocol is configured on your RADIUS server: PAP, CHAP, MSCHAP, or MSCHAP2. RADIUS Server Host Host name of the RADIUS server. To specify multiple RADIUS servers for failover, enter comma-separated names of those servers in this field. For example, server1, server2, server3. If server1 is unavailable, server2 is contacted, and if server2 is also unavailable, server3 is contacted. RADIUS Server Type Type of RADIUS server: • RSA Authentication Manager • Generic RADIUS Server • Safeword PremierAccess RADIUS Server Port Specify the port on which the RADIUS server is running. The default is 1812. RADIUS Shared Secret Specify the RADIUS shared secret string used to verify the authenticity and integrity of the messages exchanged between the Manager and the RADIUS server.
3 Running the Manager Configuration Wizard Confidential Administrator’s Guide 99 Setting up Active Directory User Authentication To authenticate users using a Microsoft Active Directory authentication server, choose Microsoft Active Directory. Communication with the Active Directory server uses LDAP and optionally SSL. The next panel prompts you for this information. Specify any user who exists in AD to test the server connection. Specify the user name used to log in to the Manager and the External ID name to which it is mapped on the AD server. Configuring AD SSL If you are using SSL between the Manager and your authentication server, you must ensure that the server’s certificate is trusted in the Manager’s trust store <ARCSIGHT_HOME>/jre/lib/security/cacerts, whether the authentication server is using self-signed or CA certificates. For CA certificates, if the Certificate Authority (CA) that signed your server’s certificate is already listed in cacerts, you do not need to do anything. Otherwise, obtain a root certificate from the CA and import it in your Manager’s cacerts using the keytoolgui utility. For more information on importing certificates, see Understanding SSL Authentication in the Administrator’s Guide. Parameter Description Active Directory Server Host name of the Active Directory Server. Enable SSL Whether the Active Directory Server is using SSL. The default is True (SSL enabled on the AD server). No further SSL configuration is required for the AD server. Whether you selected SSL earlier for communications with the Console is irrelevant. Certificate type is set on the AD server side, not the manager. Active Directory Port Specify the port to use for the Active Directory Server. If the AD server is using SSL (Enable SSL=true), use port 636. If SSL is not enabled on the AD server, use port 389. Search Base Search base of the Active Directory domain; for example, DC=company, DC=com. User DN Distinguished Name (DN) of an existing, valid user with read access to the Active Directory. For example, CN=John Doe, CN=Users, DC=company, DC=com. The CN of the user is the "Full Name," not the user name. Password Domain password of the user specified earlier. Allowed User Groups Comma-separated list of Active Directory group names. Only users belonging to the groups listed here will be allowed to log in. You can enter group names with spaces.
3 Running the Manager Configuration Wizard 100 Administrator’s Guide Confidential Setting up LDAP Authentication The ArcSight Manager binds with an LDAP server using a simple bind. To authenticate users using an LDAP authentication server, choose Simple LDAP Bind and click Next. The next panel prompts you for this information. Specify any user who exists in LDAP to test the server connection. Enter a valid Distinguished Name (DN) of a user (and that user’s password) that exists on the LDAP server; for example, CN=John Doe, OU= Engineering, O=YourCompany. This information is used to establish a connection to the LDAP server to test the validity of the information you entered in the previous panel. Specify the user name used to log in to the Manager and the External ID name to which it is mapped on the LDAP server. Configuring LDAP SSL If you are using SSL between the Manager and your authentication server, you must ensure that the server’s certificate is trusted in the Manager’s trust store <ARCSIGHT_HOME>/jre/lib/security/cacerts, whether the authentication server is using self-signed or CA certificates. For CA certificates, if the Certificate Authority (CA) that signed your server’s certificate is already listed in cacerts, you do not need to do anything. Otherwise, obtain a root certificate from the CA and import it in your Manager’s cacerts using the keytoolgui utility. For more information on importing certificates, see Understanding SSL Authentication in the Administrator’s Guide. Using a Custom Authentication Scheme From the Manager Setup Wizard, you can choose the Custom JAAS Plug-in Configuration option if you want to use an authentication scheme that you have built. (Custom Authentication is not supported from the ArcSight Management Console.) You must specify the authentication configuration in a jaas.config file stored in the ArcSight Manager config directory. Parameter Description LDAP Server Host Specify the host name of the LDAP Server. Enable SSL Whether the LDAP Server is using SSL. The default is True (SSL enabled on the LDAP server). No further SSL configuration is required for the LDAP server. Whether you selected SSL earlier for communications with the Console is irrelevant. Certificate type is set on the LDAP server side, not the manager. LDAP Server Port Specify the port to use for the LDAP Server. If the LDAP server is using SSL (Enable SSL=true), use port 636. If SSL is not enabled on the LDAP server, use port 389. LDAP groups are not supported. Therefore, you cannot allow or restrict logging into the Manager based on LDAP groups. If you configure your Manager to use LDAP authentication, ensure that you create users on the Manager with their Distinguished Name (DN) information in the external ID field. For example, CN=John Doe, OU= Engineering, O=YourCompany.
3 Running the Manager Configuration Wizard Confidential Administrator’s Guide 101 Password Based and SSL Client Based Authentication Your authentication will be based both upon the username and password combination as well as the authentication of the client certificate by the Manager. Password Based or SSL Client Based Authentication You can either use the username/password combination or the authentication of the client certificate by the Manager (for example PKCS#11 token) to login if you select this option. SSL Client Only Authentication You will have to manually set up the authentication of the client certificate by the Manager. See the Administrator’s Guide for details on how to do this. You can either use a PKCS#11 Token or a client keystore to authenticate. Using PKCS#11 provider as your SSL Client Based authentication method within this option is not currently supported.

A Administrative Commands Confidential Administrator’s Guide 107 ArcSight Commands To run an ArcSight command script on a component, open a command window and switch to the <ARCSIGHT_HOME> directory. The arcsight commands run using the file arcsight.bat (on Windows) or arcsight.sh (on Unix) in <ARCSIGHT_HOME>bin. The general syntax is as follows: binarcsight <command_name> [parameters] In general, commands that accept a path, accept either a path that is absolute or relative to <ARCSIGHT_HOME>. Running the command from <ARCSIGHT_HOME> and prefixing it with bin enables you to use the shell’s capabilities in looking for relative paths. Not all parameters are required. For example, username and password may be a parameter for certain commands, such as the Manager and Package commands, but the username and password are only required if the command is being run from a host that does not also host the Manager.

Note: Generally, there is no need to use this command. The Packages feature in the ArcSight Console is more robust and easier to use for managing resources. Applies to Manager, Console Syntax archive –f <archivefile> [Parameters] Required Parameter -f <archivefile> The input (import) or the output (export) file specification. Note: Filename paths can be absolute or relative. Relative paths are relative to <ARCSIGHT_HOME>, not the current directory. Optional Parameters -action <action> Possible actions include: diff, export, i18nsync, import, list, merge, sort, and upgrade. Default: export. -all Export all resources in the system (not including events). -autorepair Check ARL for expressions that operate directly on resource URI's. -base <basefile> The basefile when creating a migration archive. The new archive file is specified with –source (the result file is specified with –f). -config <file> Configuration file to use. Default: config/server.defaults.properties -conflict <conflictpolicy> The policy to use for conflicts resolution. Possible policies are: default: Prompts user to resolve import conflicts. force: Conflicts are resolved by the new overwriting the old. overwrite: Merges resources, but does not perform any union of relationships. preferpackage: if there is a conflict, it prefers the information in the package that is coming in over what is already there. skip: Do not import resources with conflicts.
A Administrative Commands Confidential Administrator’s Guide 113 -exportaction <exportaction> The action to assign to each resource object exported. Export actions are: insert: Insert the new resource if it doesn’t exist (this is the default). update: Update a resource if it exists. remove: Remove a resource if it exists. -format <fmt> Specifies the format of the archive. If you specify nothing, the default is default. default: Prompts user to resolve import conflicts. preferarchive: if there is a conflict, it prefers the information that is coming in over what is there. install: Use this for the first time. update: Merges the archive with the existing content. overwrite: Overwrites any existing content. -h Get help for this command. -i (Synonym for –action import.) -m <manager> The Manager to communicate with. -newids All archival objects within an archive are given new IDs. All refs to these archival objects are changed to the new ID or removed if not found. This option is useful when an archive is created and then all resources in the archive are modified to create new resources but the IDs were retained. -o Overwrite any existing files. -p <password> Password with which to log in to the Manager. -param <archiveparamsfile> The source file for parameters used for archiving. Any parameters in the named file can be overridden by command line values. -pc <configfile> Private configuration file to override –config.

For example, arcsight archive -m <hostname> -pkcs11 -f <file path> -port <port> The port to use for Manager communication. Default: 8443 -q Quiet: do not output progress information while archiving -source <sourcefile> The source file. This is used for all commands that use the -f to specify an output file and use a separate file as the input.
A Administrative Commands 114 Administrator’s Guide Confidential -standalone Operate directly on the Database, not the Manager. Warning: Do not run archive in –standalone mode when the Manager is running; database corruption could result. -u <username> The user name to log in to the Manager -uri <includeURIs> The URIs to export. No effect during import. All dependent resources are exported, as well—for example, all children of a group. Separate multiple URIs (such as “/All Filters/Geographic/West Cost”) with a space, or repeat the –uri switch -urichildren <includeURIchildren> The URIs to export (there is no effect during import). All child resources of the specified resources are exported. A parent of a specified resource is only exported if the specified resource is dependent on it. -xrefids Exclude reference IDs. This option determines whether to include reference IDs during export. This is intended only to keep changes to a minimum between exports. Do not use this option without a complete understanding of its implications. -xtype <excludeTypes> The types to exclude during export. No effect during import. Exclude types must be valid type names, such as Group, Asset, or ActiveChannel. -xtyperef <excludeTypeRefs> The types to exclude during export (there is no effect during import). This is the same as -xtype, except it also excludes all references of the given type. These must include only valid type names such as Group, Asset, and ActiveChannel. -xuri <excludeURIs> The URIs to exclude during export. No effect during import. Resources for which all possible URIs are explicitly excluded are not exported. Resources which can still be reached by a URI that is not excluded are still exported. -xurichildren <excludeURIchildren> The URIs to exclude during export (there is no effect during import). These exclusions are such that all URIs for the children objects must be included in the set before the object will be excluded. In other words, they can still be exported if they can be reached through any path that is not excluded.

A Administrative Commands 132 Administrator’s Guide Confidential restorearchives Description This command allows you to restore archive backups to a new system after a system failure. This tool assumes that you have already copied the archive backups to the location on the new system where your storage archive is located. That is, this restoration does not copy the archives into the system, you do that. It is restoring these archive entries to the new system’s database. After the command informs the system of these restored archives, they are listed on the Archives page, along with any archives that were already in the system and archives that are created later. The system does not differentiate between the archives loaded from a different installation and the ones created daily, locally. Notes: • Loading events from two installations to the local installation is not recommended. • You must stop the logger service before you run this command and restart it when you are done. • You must run this command as an ArcSight user. If the archive files’ owner is root or some other user, they cannot be reactivated. Applies to Database Syntax /opt/arcsight/logger/current/arcsight/logger/bin/arcsight restorearchives Parameters -r <root> The root directory that contains all archive backups you are restoring. All archives should be sub-directories of this directory. If unspecified, this command restores archives it finds in the default archive location, /opt/arcsight/logger/data/archives If you specify a different location the archive space used is not counted in the “Archive Jobs” administration page, and new archives still go to the default location. -i interactive Interactive mode. Confirmation is required before restoring each archive. Use this mode to select which archives to restore. -t test This option helps you validate the archives without actually loading them into the database.

It does this before the restoration operation, so you can use it to clear out the system. -h help Help for this command
A Administrative Commands Confidential Administrator’s Guide 133 resvalidate ruledesc Examples Run: /sbin/service arcsight_services stop logger /opt/arcsight/logger/current/arcsight/logger/bin/arcsight restorearchives -t to test how many archives will be restored and see if any are unreadable. /opt/arcsight/logger/current/arcsight/logger/bin/arcsight restorearchives -C to clear any existing events from the system. and then register all the backup archives you placed in /opt/arcsight/logger/data/archives /opt/arcsight/logger/current/arcsight/logger/bin/arcsight restorearchives to register all the backup archives you placed in /opt/arcsight/logger/data/archives. /sbin/service arcsight_services start logger Description Utility for checking whether there are any invalid resources in the database. The utility generates two reports called validationReport (with .xml and .html extensions) that are written to the directory from which you run the resvalidate command. Make sure you stop the Manager before you run this command. Applies to Manager, Database Syntax resvalidate Parameters -excludeTypes <exclude_resource _names> Resource type to exclude from being checked; for example, Rule, DataMonitor If specifying multiple resource types to exclude, use comma to separate them. Resource type – Rule,DataMonitor(comma separated) -out <output_dir> Output directory for validation report. If none is specified, the report is placed in the directory from which you run the resvalidate command -persist [false | true] If a resource is found to be invalid, whether to mark it invalid or only report it as invalid. For example, a rule depends on a filter that is missing. When you run the resvalidate command and –persist=false, the rule is reported as invalid but not marked invalid. However if –persist=true, the rule is marked as invalid. Default: persist=false. Examples To run, stop the Manager, then use: arcsight resvalidate Description Rule description tool to fetch rules information. (Used by HPOVO.) Tool to monitor managed objects in the Manager

Confidential Administrator’s Guide 141 Appendix B Troubleshooting The following information may help solve problems that occur while operating the ArcSight system. In some cases, the solution can be found here or in specific ArcSight documentation, but Customer Support is available if you need it. If you intend to have Customer Support guide you through a diagnostic process, please prepare to provide specific symptoms and configuration information. If you intend to do the initial diagnostic steps yourself, proceed through the following checklist systematically, trying each applicable item and noting the results for reference. This appendix is divided into the following sections: General Report is empty or missing information. Check that the user running the report has inspect (read) permission for the data being reported. Running a large report crashes the Manager. A very large report (for example, a 500 MB PDF report) might require so much virtual machine (VM) memory that it can cause the Manager to crash and restart. To prevent this scenario, you can set up the Manager to expose a special report parameter for generating the report in a separate process. The separate process has its own VM and heap, so the report is more likely to generate successfully. Even if the memory allocated is still not enough, the report failure does not crash the Manager. This option must be set up on the Manager to expose it in the Console report parameters list. The steps are as follows: “General” on page 141 “Pattern Discovery Performance” on page 143 “Query and Trend Performance Tuning” on page 143 “SmartConnectors” on page 145 “ArcSight Console” on page 146 “Manager” on page 147 “ArcSight Web” on page 148 “SSL” on page 149
B Troubleshooting 142 Administrator’s Guide Confidential 1 On the Manager in the server.properties file, set report.canarchivereportinseparateprocess=true. (This makes a new report parameter available on the Console.) 2 Save the server.properties file and restart the Manager. 3 On the ArcSight Console, open the report that you want to run in a separate process in the Report Editor, and click the Parameters tab. Set the parameter Generate Report In Separate Process to true. 4 Run the report. The report should run like a normal report, but it does not consume the resources of the Manager VM. Scheduled Rules Take too Long or Time Out If you have a system, perhaps one with a high EPS, in which the scheduled rules are not running quickly enough, you can enable them to run in parallel (multi-threading) to speed them up. Add the following property to the server.properties file: rules.replay.run.parallel=true You can also set the number of threads to use, as follows (the default if you do not use this property is four threads): rules.replay.numthreads=<number of threads to use> Some Asian language fonts appear mangled when generating reports in PDF This problem occurs because some Asian language fonts that are truetype fonts are not supported directly by versions of Adobe Reader earlier than version 8.0. In order to work around this, each truetype font must be mapped to an opentype font supported in Adobe Reader 8.0. ArcSight provides this mapping in the <ARCSIGHT_HOME>/i18n/server/reportpdf_config_<locale>.properties file. You have the option to change the default mapping of any truetype font to the opentype font by modifying the respective font mapping in this file. To work around the issue of mangled fonts, ArcSight recommends that you: 1 Install a localized Adobe Reader 8.0 depending on the language of your platform on your Manager machine. This version of the Adobe Reader installs the opentype fonts by default. 2 Edit the server.properties file as follows: a Set report.font.truetype.path property to point to the directory that contains the truetype and opentype font. The path is typically /usr/lib/font. The CIDFont directory is /usr/lib/font:<adobe_reader_dir>/Resource/CIDFont. b Set report.font.cmap.path property to point to Adobe Reader’s CMap directory. The CMap path is relative to the Adobe Reader installation -- <adobe_reader_dir>/Resource/CMap. Use this parameter only if you experience a Manager crash when running large reports such as the ones that contain tables with more than 500,000 rows and 4 or 5 columns per row.
B Troubleshooting Confidential Administrator’s Guide 143 E-mail notification doesn’t happen. If you receive the following error: [2009-12-03 14:31:33,890][WARN ][default.com.arcsight.notification.NotifierBase][send] Unable to send out e-mail notification, notifications have not been configured.  Verify the following properties are set in the server.properties file: notifications.enable=true and notifications.incoming.enable=true  Check server.properties file to find which SMTP server is associated with the Manager. Make sure that the SMTP server is up and running. Review the Notification resource and confirm the e-mail address and other configuration settings. Notification always escalates. Check server.properties file to find which POP3 or IMAP server is associated with the Manager. Make sure that the POP3 or IMAP server is up and running, in order to process acknowledgements from notification recipients. Pager notification doesn’t happen. Check server.properties file to find which SNPP server is associated with the Manager. Make sure that the SNPP server is up and running. Pattern Discovery Performance Time spread calculations can take up a lot of CPU time, especially if Pattern Discovery has been running for a long time. If performance is degraded as a result of this feature, you can find out by checking the system.log for the start and end times of the Pattern Discovery process. If it is taking linger than expected, and if that is a problem for you, turn the Time Spread feature off. To turn it off, add the property patterns.timeSpreadCalculation=False to the Manager’s server.properties file. Query and Trend Performance Tuning To improve query execution in high-EPS systems, various queries used by the trends in the default ArcSight system have been optimized. The scheduler allocates two threads for processing system tasks. This alleviates performance issues caused by conflicts between system tasks and user level tasks within the scheduler. The following sections provide some troubleshooting tips. server.defaults.properties Entries for Trends  trends.query.timeout.seconds=7200
B Troubleshooting 144 Administrator’s Guide Confidential This is the amount of time that a trend query is allowed to run, in seconds, before the SQL statement times out and the trend query fails. If absent or 0, no time-based timeout is applied.  trends.query.timeout.percent=50 This is the amount of time that a trend query is allowed to run, as a percentage of the query interval for interval trends, before the SQL statement times out and the trend query fails. If absent or 0, no percentage-based timeout is applied. As an example, with a 50 percent setting, a query covering a start/end time range of 1 hour times out after 30 minutes. A start/end time range covering 1 day would time out after 12 hours. If both timeouts are specified, the system uses the smaller of the two.  trends.query.failures.deactivation.threshold=3 If this many consecutive “accumulate” (not refresh) runs fail for any reason, the system automatically disables the trend. The check is always performed after any accumulate query run fails. Once the threshold is reached, any remaining queries to be executed by this task are skipped. If this setting is absent or 0, the checking mechanism is turned off. If a trend or query is stopped because of any of the above reasons, an audit event reflects this. Troubleshooting Checklist after Restarting the Manager  Use the Console Trend Editor to manually disable any trends that you do not need or that you notice have excessive query times. Disabling these trends helps reduce scheduler and database contention.  As trend data gathering tasks wake up, the trend attempts to fill in the gaps for missing intervals. Depending on the size of the gaps, this may take some time before the trends catch up.  A trend does not usually re-run any previously failed runs. If you want to re-run a particular time, you need to manually request it from the Trend Editor. Disable these Trends on High Throughput Systems If your system environment typically processes a very large number of events per second (EPS) (such as more than 1000 EPS or 100 million events per day), we recommend that you manually disable the following 9 trends, which are enabled by default: /All Trends/ArcSight Administration/ESM/User Access/ArcSight User Login Trends – Hourly /All Trends/ArcSight Foundation/Configuration Monitoring/Asset Configuration Change Tracking/Host Configuration Modifications /All Trends/ArcSight Foundation/Configuration Monitoring/Asset Restarts/Asset Startup and Shutdown Events - Daily Trend /All Trends/ArcSight Foundation/Configuration Monitoring/User Account Modifications/User Account Creation /All Trends/ArcSight Foundation/Configuration Monitoring/User Account Modifications/User Account Modifications /All Trends/ArcSight Foundation/Intrusion Monitoring/Operational Summaries/Reconnaissance/Port Scanning

You can use either of the following techniques, both using the ArcSight Console UI:  Using the Trend Data Viewer from within the Trends resource tree, you can see at most 2000 rows of data. (Select a trend in the resource tree, right-click, and choose Data Viewer.) Sort the trend timestamp column so that the timestamps show newest to oldest and observe when the newest value indicates it has caught up.  Using the Refresh... button in the Trend Editor, set the start time as far back as needed (days or weeks) to see any entries and click Refresh to see which runs show up as available to be refreshed. Only the most recent ones should show first. Note that you should not actually refresh any runs, but only use this technique to see what has been run. How long does it take a trend to catch up? This depends on how long the underlying query interval is, but a trend typically does up to 48 runs, as needed, when it wakes up. For a trend that queries an entire day and runs once a day, this would allow for more than a month’s worth of data to be queried. The data must be present on the system, however, or the query returns no results (but it does not fail). SmartConnectors My device is not one of the listed SmartConnectors. ArcSight offers an optional feature called the FlexConnector Development Kit which may enable you to create a custom SmartConnector for your device. ArcSight can create a custom SmartConnector. Contact Customer Support. My device is on the list of supported products, but it does not appear in the SmartConnector Configuration Wizard. Your device is likely served by a Syslog sub-connector of either file, pipe, or daemon type. Device events are not handled as expected. Check the SmartConnector configuration to make sure that the event filtering and aggregation setup is appropriate for your needs. SmartConnector not reporting all events. Check that event filtering and aggregation setup is appropriate for your needs.
B Troubleshooting 146 Administrator’s Guide Confidential Some Event fields are not showing up in the Console. Check that the SmartConnector’s Turbo Mode and the Turbo Mode of the Manager for the specific SmartConnector resource are compatible. If the Manager is set for a faster Turbo Mode than the SmartConnector, some event details are lost. SmartConnector not reporting events. Check the SmartConnector log for errors. If the SmartConnector cannot communicate with the Manager, it caches events until its cache is full. ArcSight Console Can’t log in with any Console. Check that the Manager is up and running. If the Manager is not running, start it. If the Manager is running, but you still can’t log in, suspect any recent network changes, such as the installation of a firewall that affects communication with the Manager host. Can’t log in with a specific Console. If you can log in from some Console machines but not others, focus on any recent network changes and any configuration changes on the Console host in question. Console Cannot Connect to Manager If you start an ArcSight Console that could previously connect to the Manager with no trouble, but now it can’t, see if the error is similar to: “Couldn't connect to manager - improper authorization setup between client and manager.” If so, it’s likely that the manager has been reconfigured in such a way that it now has a new certificate. Especially if the Console asked you to accept a new certificate when you started it. To fix this, find and delete the certificate that the Console was using before, and then manually import another certificate from the Manager. Console reports out of memory. This can happen when you open many independent viewing channels. If you need to do this often, change the memory settings in the console.bat or console.sh file. Find the line that starts set ARCSIGHT_JVM_OPTIONS= and change the parameter –Xmx128m to – Xmx256m. You must restart the Console for the new setting to take effect.

Confidential Administrator’s Guide 153 Appendix C The Logfu Utility This appendix is divided into the following sections: Logfu is an ArcSight utility that analyzes log files. It is indispensable for troubleshooting problems that would otherwise require poring over text logs. Logfu generates an HTML report (logfu.html) and, especially in SmartConnector mode, includes a powerful graphic view of time-based log data. Logfu pinpoints the time of the problem and often the cause as well. Logfu has two windows: the interactive Chart and the Plot/Event window. “Running Logfu” on page 154 “Example” on page 156 “Troubleshooting” on page 156 “Menu” on page 158 “Typical Data Attributes” on page 158 “Intervals” on page 159
C The Logfu Utility 154 Administrator’s Guide Confidential Running Logfu Logfu finds log files in the current directory. The –a or –m switches tell it which file names to look for. The –m switch tells it to look for all three Manager logs—server.std.log, server.log, and server.status.log—for example. To run Logfu, follow these steps: 1 Open a shell window in <ARCSIGHT_HOME>/logs/default. This refers to the logs directory under the ArcSight installation directory. Logfu requires an X Windows server. 2 Run logfu for the type of log to analyze: For Manager logs, run: ../bin/arcsight logfu –m For SmartConnector logs, run: ../bin/arcsight agent logfu –a 3 Right-click in the grid and select Show Plot/Event Window from the context menu. 4 Check at least one attribute (such as Events Processed) to be displayed. The initial display is always an empty grid. Loading very large log files can take a few minutes (a 100MB log might take 5 or 10 minutes). Once log files are scanned, the information gleaned from them is cached (in files named data.*), which speeds up loading the second time. If something about the log changes, however, you must manually delete the cache files to force logfu to reprocess the log. Right-click the grid and choose Show Plot/Event Window from the context menu. Select what to show on the grid from the Plot/Event Window that appears. The tree of possible things to display is divided into Plot—attributes that can be plotted over time, like events per second—and Event—one-time things, like exceptions, which are shown as vertical lines. Check as many things as you want to show. Because SmartConnectors can talk to multiple Managers and each can be configured to use multiple threads for events, the Plot hierarchy includes nodes for each SmartConnector and each Manager. Within the SmartConnector, threads are named E0, E1, and so on. Each SmartConnector has one heartbeat thread (H0) as well. Different types of SmartConnector
C The Logfu Utility Confidential Administrator’s Guide 155 (firewall log SmartConnector, IDS SNMP SmartConnector, and so on) have different attributes to be plotted. The interactive Chart uses sliders to change the view. Hovering over a data point displays detailed information. There are two horizontal sliders—one at the top of the grid, one underneath. The slider at the top indicates the time scale. Drag it to the right to zoom in, or widen the distance between time intervals (vertical lines). The slider at the bottom changes the interval between lines—anywhere from 1 second at the far left to 1 day at the far right. The time shown in the grid is listed below the bottom slider: Showing YY/MM/DD HH:MM:SS – YY/MM/DD HH:MM:SS (Interval= X) Click anywhere in the grid area and drag a green rectangle to zoom in, changing both the vertical and horizontal scales at once. Hold the Ctrl key as you drag to pan the window in the vertical or horizontal direction, and hold both the Shift and Ctrl keys as you drag to constrain the pan to either vertical or horizontal movement. When you are panning, only sampled data is shown, but when you stop moving, the complete data fills in. (You can change this by unchecking Enable reduced data point rendering in Preferences.) Hover the mouse over a data point to see detailed information in a “tooltip” window, as shown in the figure, above.. For each attribute being plotted, a colored, vertical slider appears on the right of the grid. This slider adjusts the vertical (value) scale of the thing being plotted. By default, data points are connected by lines. When data is missing, these lines can be misleading. To turn off lines, uncheck Connect dots in Preferences. Once you have specified attributes of interest, scaled the values, centered and zoomed the display to show exactly the information of concern, select Save as JPG on the menu to create a snapshot of the grid display that you can print or e-mail. The size of the output image is the same as the grid window, so maximize the window to create a highly detailed snapshot, or reduce the window size to create a thumbnail.
C The Logfu Utility 156 Administrator’s Guide Confidential Example Perhaps a particular SmartConnector starts by sending 10 events per second (EPS) to the Manager, but soon is sending 100, then 500, then 1000 EPS before dropping back down to 10. Logfu lets you plot the SmartConnector’s EPS over time—the result is something like a mountain peak. When you plot the Manager’s receipt of these events, you might see that it keeps up with the SmartConnector until 450 EPS or so. You notice that the Manager continues consuming 450 EPS even as the SmartConnector’s EPS falls off. This is because the Manager is consuming events that were automatically cached. By plotting the estimated cache size, you can see the whole story—the SmartConnector experienced a peak event volume and the cache stepped in to make sure that the Manager didn’t lose events, even when it couldn’t physically keep up with the SmartConnector. Use the vertical sliders on the right to give each attribute a different scale to keep the peak EPS from the SmartConnector from obscuring the plot of the Manager’s EPS. Troubleshooting Another real-world example involved a Check Point SmartConnector that was mysteriously down for almost seven days. Logfu plotted the event stream from the SmartConnector and it was clearly flat during the seven days, pinpointing the outage as well as the time that the event flow resumed. By overlaying Check Point Log Rotation events on the grid, it became clear that the event outage started with a Log Rotation and that event flow resumed coincident with a Log Rotation. Further investigation revealed what had happened—the first Check Point Log Rotation failed due to lack of disk space, which shut down event flow from the device. When the disk space problem had been resolved, the customer completed the Log Rotation and event flow resumed. If the Manager suddenly stops seeing events from a SmartConnector Logfu helps determine whether the SmartConnector is getting events from the device. Another common complaint is that not all events are getting through. Logfu has a plot attribute called ‘ZFilter’—zone filter—that indicates how many raw device events are being filtered by the SmartConnector. Events processed (the number of events sent by the device) minus

Confidential Administrator’s Guide 161 Appendix D Creating Custom E-mails Using Velocity Templates This appendix describes how to modify Velocity templates to customize e-mail messages you receive from the ArcSight notification system. This appendix is divided into the following sections: A sample use case is presented to illustrate the concept. Overview ArcSight supports the use of Velocity templates that are a means of specifying dynamic input to the underlying Java code. You can apply Velocity templates in a number of places in ArcSight. For a complete list of Velocity template applications in ArcSight, see the Console online Help. This section describes one such application—E-mail Notification Messages—in detail. You can use Velocity templates on your Manager to create custom e-mail messages to suit your needs. Notification Velocity templates The <ARCSIGHT_HOME>/Manager/config/notifications directory contains the following two Velocity templates for customizing e-mail notifications:  Email.vm—The primary template file that calls secondary template files.  Informative.vm—The default secondary template file. Commonly used elements in Email.vm and Informative.vm files It is important to understand the commonly used Velocity programming elements in the Email.vm and Informative.vm files before editing these files. “Overview” on page 161 “Notification Velocity templates” on page 161
D Creating Custom E-mails Using Velocity Templates 162 Administrator’s Guide Confidential The #if statement The general format of the #if statement for string comparison is: #if ($introspector.getDisplayValue($event, ArcSight_Meta_Tag) Comparative_Operator Compared_Value) The #if statement for integer comparison is: #if ($introspector.getValue($event, ArcSight_Meta_Tag).intValue()Comparative_Operator Compared_Value) You can specify ArcSight_Meta_Tag, Comparative_Operator, and Compared_Value to suit your needs. ArcSight_Meta_Tag is a string when using the #if statement for string comparison (for example, displayProduct) and is an integer for the #if statement for integer comparison (for example, severity). For a complete listing of ArcSight meta tags, see the Token Mappings topic in ArcSight FlexConnector Guide. Comparative_Operator is == for string comparison; =, >, and < for integer comparison. Compared_Value is a string or an integer. For string comparison, enclose the value in double quotes (“ ”). Contents of Email.vm and Informative.vm The default Email.vm template file contents are: ## This is a velocity macro file... ## The following fields are defined in the velocity macro. ## event == the event which needs to be sent. ## EVENT_URL == root of the event alert. ## NOTIFICATION_URL == URL of the notifications page in ArcSight Web #parse ("Informative.vm") This message can be acknowledged in any of the following ways: 1) Reply to this email.

D Creating Custom E-mails Using Velocity Templates Confidential Administrator’s Guide 163 #foreach( $field in $introspector.fields ) #if( $introspector.getDisplayValue($event, $field).length() > 0 ) ${field.fieldDisplayName}: $introspector.getDisplayValue($event, $field) #end #end Using Email.vm and Informative.vm Template Files Email.vm calls the secondary template file Informative.vm (#parse (“Informative.vm”)). The Informative.vm file lists all the non-empty fields of an event in the format fieldName : fieldValue. Understanding the Customization Process If you want to customize the template files to suit your needs, ArcSight recommends that you create new secondary templates containing fields that provide information you want to see in an e-mail for a specific condition. For example, if you want to see complete details for an event—Threat Details, Source Details, Target Details, and any other information—generated by all Snort devices in your network, create a secondary template file called Snort.vm in <ARCSIGHT_HOME>/config/notification, on your Manager, with the following lines: === Complete Event Details === Threat Details Event: $introspector.getDisplayValue($event,"name") Description: $introspector.getDisplayValue($event,"message") Severity: $introspector.getDisplayValue($event,"severity") ------------------------------------------------------------------ Source Details Source Address: $introspector.getDisplayValue($event,"attackerAddress") Source Host Name: $introspector.getDisplayValue($event,"attackerHostName") Source Port: $introspector.getDisplayValue($event,"sourcePort") Source User Name: $introspector.getDisplayValue($event,"sourceUserName") ------------------------------------------------------------------ Target Details

Confidential Administrator’s Guide 167 Appendix E Configuration Changes Related to FIPS This appendix provides information about and instructions for configuring ArcSight Express to support Federal Information Processing Standard (FIPS) 140-2 and some other configuration changes you can make while in FIPS mode. FIPS is a standard published by the National Institute of Standards and Technology (NIST) and is used to accredit cryptographic modules in software components. A cryptographic module is either hardware or software or a combination that is used to implement cryptographic logic. The US Federal government requires that all IT products dealing with Sensitive, but Unclassified (SBU) information meet the FIPS standard.  To be compliant with FIPS 140-2, all components, including Connectors and Logger, if present, must be configured in FIPS mode. Connectors and Logger setup are covered in their documentation. For connectors, refer to each connector’s configuration guide and also see the Connector Management User’s Guide.  For information about supported platforms and specifics about FIPS mode architecture for all ArcSight Express products, contact ArcSight Customer Support.  TLS is based on SSL 3.0, for a better understanding of how SSL works. Read the section “Understanding SSL Authentication” on page 31. “Tools Used to Configure Components in FIPS” on page 168 “Types of Certificates Used in FIPS Mode” on page 168 “Some Often-Used SSL-Related Procedures” on page 172 “Setting up Server-Side Authentication” on page 177 “Setting up Client-Side Authentication” on page 177 “Changing the Password for NSS DB” on page 178 “Listing the Contents of the NSS DB” on page 179 “Veiwing the Contents of a Certificate” on page 179 “Setting the Expiration Date of a Certificate” on page 180 “Deleting a Certificate from NSS DB” on page 180 “Replacing an Expired Certificate” on page 180 “Using the Certificate Revocation List (CRL)” on page 181 “Changing a Default Mode Installation to FIPS 140-2” on page 184 “Configure Your Browser for FIPS” on page 188
E Configuration Changes Related to FIPS 168 Administrator’s Guide Confidential Tools Used to Configure Components in FIPS Network Security Services (NSS) is a cross-platform cryptographic C library and a collection of security tools. ArcSight Express comes bundled with the following three basic NSS command line tools:  runcertutil - is a certificate and key management tool used to view and generate key pairs and certificate signing requests (CSR) and import and export public certificates from key pairs.  runmodutil - is the NSS module configuration tool. It is used to enable or disable the FIPS module and change key store passwords.  runpk12util - is an import and export tool for PKCS #12 format key pairs (.pfx files). See Appendix A‚ Administrative Commands‚ on page 105 for details on the above command line tools. You can also refer to the ‘NSS Security Tools’ page on the Mozilla website for more details on any of the above NSS tools (search for them as certutil, modutil, or pk12util). For online help on any command, enter the following command from a component’s bin directory: ./arcsight <command_name> -H References to ARCSIGHT_HOME <ARCSIGHT_HOME> in the paths represents  /opt/arcsight/manager for the Manager,  /opt/arcsight/console/current for the Console  /opt/arcsight/web for ArcSight Web. Types of Certificates Used in FIPS Mode When dealing with certificate based identification and encryption, components fall into one of two categories: servers and clients. Signed certificates enable these components to verify the validity of communications with the other components. You can use either a self- signed certificate or a CA-signed certificate when setting up SSL authentication on your ArcSight Express components. Enabling FIPS, SSL authentication, and certificate management for connectors is covered in the Connector Management User’s Guide. Using a Self-Signed Certificate When you use a self-signed certificate, the public part of the server’s key is used to identify and encrypt communications between the client and server. A self-signed certificate is automatically generated when doing a fresh installation of ArcSight Express. The runcertutil tool currently has a limitation that it cannot import the certificate when the NSS DB is set to FIPS mode. In order to work around this issue, you have to disable FIPS mode in the NSS DB, import the certificate, and then re-enable FIPS mode.
E Configuration Changes Related to FIPS Confidential Administrator’s Guide 169 Using a Certificate Authority (CA) Signed Certificate In a configuration using a CA-signed certificate, the public part of the server’s key is sent to the client and the client identifies it using the Certificate Authority’s root certificate. The root certificate identifies the validity of the certificate by matching itself against the Issuer section of the public certificate. To obtain a CA signed certificate there are two options. 1 Buy or obtain a keypair from a Certificate Authority (CA). When putting in server data for your new server certificate, verify that the Subject Common Name (CN) matches the Fully qualified hostname (FQDN) or IP address of your server. 2 From your manager, Generate a Certificate Signing Request (CSR). Send the CSR to a Certificate Authority and retrieve the new keypair from the CA. After acquiring your new CA Signed Keypair, import it into the nssdb using the runpkcs12util utility. For all clients connecting to the server that uses the CA signed certificates, import the CA’s root certificate. It will be used to validate the certificate from the server. The instructions in this section for converting from the default self-signed certificates to a CA signed certificate assume that the Manager is already running in FIPS mode. For information on managing certificates for connectors, refer to the Connector Management User’s Guide. Steps Performed on the Manager Below are the steps to configure your ArcSight server application to use a CA signed certificate in fips 140-2 mode. 1 Stop the Manager. 2 Find out what the common name is 3 Delete any previously imported/generated Manager certificate or key pair. (Make sure you know the common name (CN) it uses before you delete it, because the new certificate needs to use the same CN.) ./arcsight runcertutil -D -n mykey -d /opt/arcsight/manager/config/jetty/nssdb 4 Generate a certificate signing request (CSR) by running the following from the Manager’s /bin directory: To create a PEM ASCII format CSR file: ./arcsight runcertutil -R -s "CN=<previous_CN>, O=<Name_of_organization>, L=<City_where_the_organization_is_located>, ST=<State_where_organization_is_located>, C=<Country>" -a -o <absolute_path_to_filename.csr> -d /opt/arcsight/manager/config/jetty/nssdb If you do not specify the absolute path to where the .csr file should go, the path specified for the output file will be relative to <ARCSIGHT_HOME> (/opt/arcsight/manager).
E Configuration Changes Related to FIPS 170 Administrator’s Guide Confidential To create a DER binary file: ./arcsight runcertutil -R -s "CN=<hostname_or_IP>, O=<Name_of_organization>, L=<City_where_the_organization_is_located>, ST=<State_where_organization_is_located>, C=<Country>" -o <absolute_path_to_filename.csr> -d /opt/arcsight/manager/config/jetty/nssdb Enter the password for the NSS DB when prompted. The default is described in “NSS database password” on page 35. Enter random keyboard strokes when prompted to generate the random seed to generate your key. The CSR is generated in the location specified by the -o option. 5 Send the .csr file to your Certificate Authority. The Certificate Authority sends you a key pair consisting of a private key and a public certificate sighed by the CA. 6 After you receive the signed certificate from the CA, import it into the Manager’s NSS DB by running these commands from the Manager’s /bin directory: ./arcsight runcertutil -A -n mykey -t "C,C,C" -d /opt/arcsight/manager/config/jetty/nssdb -i <absolute_path_to_the_signed_certificate> 7 Start the Manager by running the following command as user arcsight: /sbin/service arcsight_services start manager Steps Performed on ArcSight Web ArcSight Web plays a dual role. On one hand, it acts as a client to the Manager to which it connects. On the other, it acts as a server to web browsers that connect to it. Therefore, ArcSight Web authenticates the Manager to which it connects and it also has to authenticate itself to web browsers. To authenticate the Manager, ArcSight Web’s NSS DB should contain the CA’s root certificate. At the same time, since the Web acts as a server to the web browsers that connect to it, you should have a key pair and a certificate containing ArcSight Web’s public key in the Web’s NSS DB. This allows ArcSight Web to authenticate iteself to the web browsers. You import the CA’s root certificate into ArcSight Web’s webnssdb. To obtain a CA-signed certificate for ArcSight Web, generate a key pair on ArcSight Web, generate a CSR on ArcSight Web, and send the CSR to the CA. Lastly, after you receive the signed certificate from the CA, import it into the webnssdb. 1 Stop ArcSight Web, if it is running. Delete any previously imported/generated Manager certificate or key pair. (Make sure you know the common name (CN) it uses before you delete it, because the new certificate needs to use the same CN.) ./arcsight runcertutil -D -n mykey -d /opt/arcsight/web/config/jetty/webnssdb
E Configuration Changes Related to FIPS Confidential Administrator’s Guide 171 2 Import the CA’s root certificateinto the webnssdb by running the following from ArcSight Web’s bin directory. (For the -t option, make sure the you specify “CT,C,C” exactly as shown.) ./arcsight runcertutil -A -n <certificate_alias> -t "CT,C,C" -d /opt/arcsight/web/config/jetty/webnssdb -i <absolute_path_to_the_CA’s_root_certificate> This is required in order for ArcSight Web to be able to authenticate the Manager. 3 Generate a key pair on ArcSight Web by running: 4 Generate a CSR in the webnssdb which you have to send to the CA to obtain a CA- signed certificate for ArcSight Web: ./arcsight runcertutil -R -s "CN=<previous_CN>, O=<company_name>, L=<Location_of_the_company>, ST=<State_where_company_is_located>, C=<country>" -a -o <absolute_path_to_the_filename.csr> -d /opt/arcsight/web/config/jetty/webnssdb This generates a CSR file that is placed in the location you had specified in the -o option in the command. 5 Send the .csr file to your Certificate Authority. The Certificate Authority sends you a key pair consisting of a private key and a public certificate sighed by the CA. 6 After you receive ArcSight Web’s signed certificate from the CA, import it into ArcSight Web’s webnssdb by running: ./arcsight runcertutil -A -n mykey -t "C,C,C" -d /opt/arcsight/web/config/jetty/webnssdb -i <absolute_path_to_ArcSight_Web_certificate> The web browsers that connect to the webserver use ArcSight Web’s certificate to authenticate the webserver. 7 Start ArcSight Web by running the following from its /bin directory as user arcsight: /sbin/service arcsight_services start arcsight_web Steps Performed on the ArcSight Console You are required to import the CA root certificate into the Console’s nssdb.client. This allows the Console to trust the Manager. • Make sure the CN is either the IP address of the machine on which ArcSight Web resides or its fully qualified domain name used in the URL when you access ArcSight Web using a browser. • If you do not specify the absolute path to where the .csr file should go, the path specified for theoutput file will be relative to <ARCSIGHT_HOME> (/opt/arcsight/web). Make sure that you have copied the CA root certificate to the machine on which install the ArcSight Console.
E Configuration Changes Related to FIPS 172 Administrator’s Guide Confidential 1 Import the root certificate from the Certificate Authority (CA) used to sign the managers certificate by running: arcsight runcertutil -A -n <provide_an_alias_for_the_cert> -t “CT,C,C” -d <ARCSIGHT_HOME>currentconfignssdb.client -i <path_to_the_CA’s_root_certificate> For the -t option, be sure to use CT,C,C permission flags only and in the order shown above. 2 Start the Console. You should see a message saying that the Console is starting in FIPS mode. Some Often-Used SSL-Related Procedures Here are some of the commonly used SSL-related procedures that are intended to serve as a reference when installing or setting up ArcSight Express components in FIPS mode. Generating a Key Pair in a Component’s NSS DB This section explains how to generate a key pair in a component’s NSS DB. A component that has to authenticate itself is required to have a key pair on it. For example, during server-side authentication, since the server needs to authenticate itself to a client, the server should have a key pair in its NSS DB and send its certificate which contains the server’s public key to the client requesting it. The same is true for client-side authentication where a key pair has to exist on the client. For self-signed certificate, the certificate gets generated when generating a key pair. On the Manager 1 Run the following command from the Manager’s <ARCSIGHT_HOME>/bin directory to generate a key pair: ./arcsight runcertutil -S -s “CN=<hostname>” -v <number_of_months_the_certificate_should_be_valid> -n mykey -k rsa -x -t “C,C,C” -m 1234 -d /opt/arcsight/manager/config/jetty/nssdb When you import or generate a key pair in a component’s NSS DB, if there is a existing key pair/certificate that has the same CN as the one you create, the runcertutil utility uses the existing alias for the newly created key pair and ignore the alias you supplied in the runcertutil command line. • Make sure to use mykey as the alias name for the key pair as shown in the example. • The -m serial number should be unique within nssdb • The hostname is the short name or fully qualified domain name depending upon how your Manager name was set up when you installed the Manager. • Using -v to set the validity period of your certificate is optional. Using -v is optional. If you choose to use it, see “Setting the Expiration Date of a Certificate” on page 180 for details. To dee the validity period of an existing certificate, see “Viewing Certificate Details” on page 40.
E Configuration Changes Related to FIPS Confidential Administrator’s Guide 173 In the above command, the hostname is the name of the machine on which your Manager is installed and -v is the validity period of the certificate. For example, if your hostname is myhost.arcsight.com, you would run: ./arcsight runcertutil -S -s “CN=myhost.arcsight.com” -v 6 -n mykey -k rsa -x -t “C,C,C” -m 1234 -d /opt/arcsight/manager/config/jetty/nssdb This generates a key pair and certificate with the alias mykey which is valid for 6 months from the current date and time in the Manager’s nssdb. 2 Enter the password for NSS DB when prompted. The default is described in “NSS database password” on page 35. 3 Enter random keyboard strokes when prompted, to generate the random seed used to generate your key. On ArcSight Web To create a key pair on the Web server: 1 Run the following command from ArcSight Web’s /bin directory: ./arcsight runcertutil -S -s “CN=<hostname>” -v <number_of_months_the_certificate_should_be_valid> -n mykey -k rsa -x -t “C,C,C” -m 2345 -d <ARCSIGHT_HOME>/config/jetty/webnssdb  The -m serial number (2345) must be unique within webnssdb. That is, it must be different than the one for the Manager’s key pair.  hostname is the name of the machine on which ArcSight Web is installed.  Using -v is optional. If you choose to use it, see “Setting the Expiration Date of a Certificate” on page 180 for details. 2 Enter the password for webnssdb. The default is described in “NSS database password” on page 35. 3 Enter random keyboard strokes when prompted, to generate the random seed used to generate your key. Verifying Whether the Key pair Has Been Successfully Created To verify whether the key pair has been successfully created in the nssdb, run the following from the component’s <ARCSIGHT_HOME>/bin directory: ./arcsight runcertutil -L -d <path_to_the_component’s_NSS DB> Viewing the Contents of the Manager Certificate If you would like to check the contents of the certificate, you run this from the component’s /bin directory: ./arcsight runcertutil -L -d <path_to_the_component’s_NSS DB> - n mykey When you import or generate a key pair into NSS DB, if there is a existing key pair/certificate with the same CN as the one you create, the runcertutil utility uses the existing alias for the newly created key pair and ignores the alias you supplied in the runcertutil command line.
E Configuration Changes Related to FIPS 174 Administrator’s Guide Confidential Exporting Certificates This section explains how to export a certificate from a component’s NSS DB. During an SSL handshake, for server side authentication, you need to have the server’s certificate in the NSS DB of both the server and the client. Export the server’s certificate from the server’s NSS DB in order to import it into the client that wishes to connect to the server. Likewise, for client side authentication, you need to have the client’s certificate in the NSS DB of both the client and the server. Export the client’s certificate from the client’s NSS DB in order to import it into the server to which the client connects. For information on managing certificates for connectors, refer to the Connector Management User’s Guide. Exporting a Certificate From the Manager Run the following command from the Manager’s <ARCSIGHT_HOME>/bin directory: ./arcsight runcertutil -L -n <alias_for_exported_certificate> -r -d /opt/arcsight/manager/config/jetty/nssdb -o <absolute_path_to_where_you_want_certificate_exported> For example: ./arcsight runcertutil -L -n mykey -r -d /opt/arcsight/manager/config/jetty/nssdb -o /home/arcsight/arcsight/Manager/ManagerCert.cer This exports the Manager’s certificate into a file called ManagerCert.cer and places it in your /home/arcsight/arcsight/Manager directory. The alias for this file is mykey. Exporting a Certificate From the Console To export the Console’s certificate run the following from the Console’s bin directory: arcsight runcertutil -L -n <alias_for_exported_certificate> -r -d <ARCSIGHT_HOME>currentconfignssdb.client -o <absolute_path_to_where_you_want_certificate_exported> Exporting a Certificate From the Web To export the Web’s certificate, run the following from the Web’s /bin directory: If you do not specify the absolute path for the .cer file, it is placed in the Manager’s <ARCSIGHT_HOME> directory. If you do not specify the absolute path for the .cer file, it gets placed in the Console’s <ARCSIGHT_HOME> folder.
E Configuration Changes Related to FIPS Confidential Administrator’s Guide 175 ./arcsight runcertutil -L -n <alias_for_exported_certificate> -r -d /opt/arcsight/web/config/jetty/webnssdb -o <full_path_to_where_you_want_certificate_exported> Importing a Certificate into the NSS DB This section explains how to import a certificate into a component’s NSS DB. For server side authentication, the server’s certificate needs to be imported into the client’s NSS DB. For client side authentication, the client’s certificate needs to be imported into the server’s NSS DB. Use runcertutil to import a certificate into the NSS DB. The runcertutil tool currently has a limitation that it cannot import the certificate when the component is running in FIPS mode. In order to work around this issue, you have to disable FIPS mode on the component first, then import the certificate, and lastly re-enable FIPS mode. For information on managing certificates for connectors, refer to the Connector Management User’s Guide. On the Manager If you use a CA-signed certificate, import the Manager’s CA-signed certificate into the Manager’s nssdb. In addition, if you set up client side authentication, import the client’s certificate into the Manager’s nssdb. Import a certificate into the Manager’s nssdb by running: ./arcsight runcertutil -A -n <provide_an_alias_for_the_certificate> -t “CT,C,C“ -d /opt/arcsight/manager/config/jetty/nssdb -i <absolute_path_to_the_certificate_file> For the -t option, be sure to use CT,C,C permissions flags only and in the same order that it is shown above. If you are importing the Console’s certificate to set up client-side authentication, make sure that you do NOT use the alias mykey for the Console’s certificate when importing it into the Manager’s nssdb because the nssdb already has the Manager’s certificate with the alias mykey in it. All aliases in the nssdb should be unique. On the Console Import the Manager’s certificate into the Console that connects to the Manager. To import a certificate into the Console’s nssdb.client: arcsight runcertutil -A -n <provide_an_alias_for_the_cert> -t “CT,C,C” -d <ARCSIGHT_HOME>confignssdb.client -i <absolute_path_to_certificate_file> For the -t option, be sure to use CT,C,C permissions flags only and in the same order that it is shown above. On ArcSight Web To import the Manager’s certificate into ArcSight Web’s webnssdb: If you do not specify the absolute path for the .cer file, it gets placed in the Web’s optarcsightweb folder.
E Configuration Changes Related to FIPS 176 Administrator’s Guide Confidential ./arcsight runcertutil -A -n <provide_an_alias_for_the_cert> -t “CT,C,C” -d /opt/arcsight/web/config/jetty/webnssdb -i <absolute_path_to_the_certificate_file> For the -t option, be sure to use CT,C,C permissions flags only and in the same order that it is shown above. Importing an Existing Key Pair into the NSS DB If you already have an existing key pair, you can use it instead of generating a new key pair on a component. This procedure instructs you how to import an existing key pair into a component’s NSS DB. 1 Export the key pair using a tool, such as keytoolgui, and be sure to export the key pair with the name you gave it. An alias is required in order to import the key pair into NSS DB. 2 Import the .pfx file into NSS DB using the runpk12util tool. Make sure that the alias of the key pair being imported does not match the alias of a pre-existing key pair in the component’s NSS DB. If the key pair being imported has an alias that matches a pre-existing key pair, the key pair fails to import citing an error: PKCS12 decode validate bags failed: The user pressed cancel. Run the following command from the component’s /bin directory On the Manager: ./arcsight runpk12util -i <absolute_path_to_mykey.pfx> -d /opt/arcsight/manager/config/jetty/nssdb On the Web: ./arcsight runpk12util -i <absolute_path_to_mykey.pfx> -d /opt/arcsight/web/config/jetty/webnssdb On the Console: arcsight runpk12util -i <absolute_path_to_mykey.pfx> -d <ARCSIGHT_HOME>currentconfignssdb.client 3 Run the following from the component’s <ARCSIGHT_HOME>/bin directory to verify that the key pair has been imported correctly. Note that the alias of the key pair that you just imported in the NSS DB is the same as the alias of that key pair in the .pfx file, in our example, mykey. On Manager: ./arcsight runcertutil -L -d /opt/arcsight/manager/config/jetty/nssdb On Web: ./arcsight runcertutil -L -d /opt/arcsight/web/config/jetty/webnssdb You should see the alias of the imported key pair in the output.
E Configuration Changes Related to FIPS Confidential Administrator’s Guide 177 Setting up Server-Side Authentication When you install a component in FIPS mode, you set it up for server-side authentication. Setting up client-side authentication is optional. Setting up Client-Side Authentication SSL 3.0 supports client-side authentication. TLS is based on SSL 3.0. ArcSight Express uses TLS and supports client-side authentication. The client side authentication takes place after the initial handshake (after the Manager has authenticated itself to the Console). The Manager then requests the Console for its (Console’s) certificate. The Console in turn sends its certificate to the Manager. The Manager has to be configured to accept the Console’s certificate. In other words, the Console’s certificate must exist in the Manager's nssdb prior to the Manager authenticating the Console. With this high level overview in mind, here are the steps you need to perform to set up client-side authentication. If you plan to use self-signed certificate for the Console: 1 Stop the Console if it is running. 2 Generate a key pair in the Console’s nssdb.client. Follow the steps in “Generating a Key Pair in a Component’s NSS DB” on page 172 (“On the Console” subsection). This automatically generates a self-signed certificate on the Console’s NSS DB. Alternatively, you can use an existing key pair which you have to import into the Console’s NSS DB. See “Importing an Existing Key Pair into the NSS DB” on page 176 for details. 3 Export the Console’s certificate. See the section “Exporting Certificates” on page 174 (“From the Console” subsection) for detailed instructions. 4 Stop the Manager if it is running. 5 Import the Console’s certificate into the Manager’s nssdb. See the section “Importing a Certificate into the NSS DB” on page 175 (“On the Manager” subsection) for details. 6 Restart the Manager, then Console. If you plan to use CA-signed certificate for the Console: 1 Stop the Console if it is running. 2 Generate a key pair on the Console. See the “Generating a Key Pair in a Component’s NSS DB” on page 172 for details. 3 Generate a CSR on the Console by running the following from the Console’s bin directory: arcsight runcertutil -R -s "CN=<hostname_or_IP>, O=<Name_of_organization>, L=<City_where_the_organization_is_located>, ST=<State_where_organization_is_located>, C=<Country>" -a -o Make sure that you do NOT use the alias mykey for the certificate when importing it into the Manager’s nssdb because the nssdb already has the Manager’s certificate with the alias mykey in it. All aliases in the nssdb must be unique.
E Configuration Changes Related to FIPS 178 Administrator’s Guide Confidential <absolute_path_to_filename.csr> -d <ARCSIGHT_HOME>currentconfignssdb.client 4 Send the CSR file to your CA and obtain a signed certificate from your CA. 5 Import the CA-signed certificate into the Console’s nssdb.client. See “Importing a Certificate into the NSS DB” on page 175 (subsection “On the Console”) for details. 6 Stop the Manager if it is running. 7 Import the Console’s CA-signed certificate into the Manager’s nssdb. See “Importing a Certificate into the NSS DB” on page 175 (subsection “On the Manager”) for details. Changing the Password for NSS DB ArcSight Express ships with a default password for the NSS DB (see “NSS database password” on page 35). ArcSight recommends that you change the password on each component before moving to a production environment. To do so: 1 Disable the FIPS mode in NSS DB by running the following from the component’s /bin directory: ./arcsight runmodutil -fips false -dbdir <absolute_path_to_the_component’s_NSS DB> 2 Run the following to list the NSS DB’s token name: ./arcsight runmodutil -list -dbdir <absolute_path_to_the_component’s_NSS DB> 3 Change the token’s password by running the following from the component’s /bin directory: ./arcsight runmodutil -changepw “<name_of_token>” -dbdir <absolute_path_to_the_component’s_NSS DB> 4 Enter the old password and a new password and confirm it when prompted. 5 Re-enable FIPS mode on the NSS DB: ./arcsight runmodutil -fips true -dbdir <absolute_path_to_the_component’s_NSS DB> 6 Open the properties file: On the Manager: Located in: /opt/arcsight/manager/config/server.properties. Change server.privatekey.password.encrypted=<encrypted_password> to server.privatekey.password=<new_unencrypted_password> On the Console: If you do not specify the absolute path to where you want the .csr file to be placed, the .csr file gets placed in the Console’s <ARCSIGHT_HOME>.
E Configuration Changes Related to FIPS Confidential Administrator’s Guide 179 Located in <ARCSIGHT_HOME>currentconfigconsole.properties Change console.privatekey.password.encrypted=<encrypted_password> to console.privatekey.password=<new_unencrypted_password> On the Web: Located in <ARCSIGHT_HOME>/config/webserver.properties. Change webserver.privatekey.password.encrypted=<encrypted_password> to webserver.privatekey.password=<new_unencrypted_password> 7 Run the setup program from the component’s /bin directory: Manager: ./arcsight managersetup Console: arcsight consolesetup Web: ./arcsight webserversetup and accept all the defaults in the wizard. This is required in order to obfuscate the password that you had entered in plain text. Listing the Contents of the NSS DB After you import a certificate or generate a key pair in a component’s NSS DB, you can verify that the certificate import was successful or the key pair has been successfully generated. You can do this by listing the contents of the NSS DB. To view the contents of a component’s NSS DB, run the following command from the component’s /bin directory: ./arcsight runcertutil -L -d <absolute-path-to-the_component’s_NSS DB> You should see the alias of the certificate you just imported or the alias for the key pair you generated. Veiwing the Contents of a Certificate To view the contents of a certificate, run the following command from the component’s /bin directory: ./arcsight runcertutil -L -d <absolute-path-to-the_component’s_NSS DB> -n <certificate_alias>
E Configuration Changes Related to FIPS 180 Administrator’s Guide Confidential Setting the Expiration Date of a Certificate To set the expiry date of the certificate, you have to do so when generating the key pair. Once you have generated the key pair, you cannot change the expiration date on the certificate and the certificate expires in three months by default. ./arcsight runcertutil -S -s “CN=<hostname>” -v <number_of_months_the_certificate_should_be_valid> -n mykey -k rsa -x -t “C,C,C” -m 1234 -d <component’s_NSS DB_path> You specify the validity of the certificate with the -v <number_of_months> option. The value that you provide with -v calculates the number of months that the certificate is valid starting from the current time. You can use the -w <offset_months> along with -v to set the beginning time for the validity. The -w <offset_months> if used, calculates the start time of the certificate validity and the offset is calcualted from the current system time. If you do not use the -w option, the current time is used as the start time for the certificate validity. See the subsection, “runcertutil” in Appendix A‚ Administrative Commands‚ on page 105 for details on the -v and -w options. Deleting a Certificate from NSS DB To delete a certificate from a component’s NSS DB: 1 Stop the component if it is running. 2 Run the following command from the component’s /bin directory: ./arcsight runcertutil -D -n <certificate-alias> -d <absolute- path-to-the_component’s_NSS DB> Replacing an Expired Certificate When an existing certificate/nssdb expires on a server (Manager or Web), you need to replace it with a new one. You can see when a certificate will expire by opening it. To replace the certificate: 1 Stop all services by running the following command (as user arcsight): /sbin/service arcsight_services stop all 2 Delete the expired certificate from the server’s NSS DB. See “Deleting a Certificate from NSS DB” on page 180 for details. Since the common name (CN) for the new certificate is identical to the CN in the old certificate, you are not permitted to have both the expired as well as the new certificate co-exist in the NSS DB. 3 In case of CA-signed certificate, replace the certificate by importing the new certificate into the server’s NSS DB. In case of self-signed certificate, you have to generate a key pair on the server. See “Generating a Key Pair in a Component’s NSS DB” on page 172 for details on how to do this. Generating the key pair automatically generates the certificate. 4 On every client that connects to the server, make sure to delete the old expired server certificate from the client’s NSS DB and import the server’s newly generated certificate. For example, if your Manager’s certificate has expired, you have to
E Configuration Changes Related to FIPS Confidential Administrator’s Guide 181 a Delete the expired certificate from the Manager’s nssdb. See “Deleting a Certificate from NSS DB” on page 180 b Generate a new key pair, which automatically generates a new self-signed certificate. See “Generating a Key Pair in a Component’s NSS DB” on page 172 c Export the newly generated certificate from the Manager. See “Exporting Certificates” on page 174 d Delete the expired Manager’s certificate from the Console’s and Web’s NSS DB. e Generate a new keypair in the Web’s nssdb which effectively generates a new certificate on the Web. See “Generating a Key Pair in a Component’s NSS DB” on page 172 f Import the Manager’s new certificate into the Console’s and Web’s NSS DB. See “Importing a Certificate into the NSS DB” on page 175 Using the Certificate Revocation List (CRL) Starting in v4.0 SP2, ArcSight Express supports the use of CRL to revoke a CA-signed certificate which has been invalidated. The CA that issued the certificates also issues a CRL file which contains a signed list of certificates which it had previously issued that it now considers invalid. The Manager checks the client certificates against the list of certificates listed in the CRL and denies access to clients whose certificates appear in the CRL. Before you use the CRL feature, make sure:  Your certificates are issued/signed by a valid Certificate Authority or an authority with an ability to revoke certificates.  The CA’s certificate is present in the Manager’s /opt/arcsight/manager/config/jetty/nssdb directory In the case of client-side authentication, the Manager validates the authenticity of the client certificate using the certificate of the signing CA.  You have a current CRL file provided by your CA. The CA updates the CRL file periodically as and when additional certificates get invalidated. To use the CRL feature: 1 Make sure you are logged out of the Console. 2 Copy the CA-provided CRL file into your Manager’s /opt/arcsight/manager/config/jetty/crls directory. After adding the CRL file, it takes about a minute for the Manager to get updated. Configuration Required to Support Suite B Suite B is a set of cryptographic algorithms put forth by the National Security Agency (NSA) as part of the national cryptographic technology. While FIPS 140-2 supports sensitive but unclassified information, FIPS with Suite B supports both unclassified information and most classified up to top secret information. In addition to AES, Suite B includes cryptographic algorithms for hashing, digital signatures, and key exchange. When configured to use Suite B mode, ArcSight Express supports Suite B Transitional profile. There are 2 level of security defined in Suite B mode:
E Configuration Changes Related to FIPS 182 Administrator’s Guide Confidential  TLS_ECDHE_ECDSA_WITH_AES_128_CBC_SHA Suite B 128-bit security level, providing protection from classified up to secret information  TLS_ECDHE_ECDSA_WITH_AES_256_CBC_SHA Suite B 192-bit security level, providing protection from classified up to top secret information Generating a Keypair on the Manager The key pair you generate is used to generate the self-signed certificate. The self-signed certifcate automatically gets generated when you generate the key pair. The Manager’s key pair and certificate get generated and stored in its nssdb. The Manager’s public key is embedded in its certificate, thereby linking the Manager’s identity to its public key. a Run the following command from the Manager’s <ARCSIGHT_HOME>/bin directory to generate a key pair. This automatically generates the Manager’s certificate. If you want to set the expiry date of the certificate, you have to do so when generating the key pair. Once you have generated the key pair, you cannot change the expiry date on the certificate. ./arcsight runcertutil -S -s “CN=<hostname>” -v <number_of_months_the_certificate_should_be_valid> -n mykey -k ec -q secp521r1 -x -t “C,C,C” -m 1234 -d /opt/arcsight/manager/config/jetty/nssdb For example, if your hostname is host.arcsight.com, you would run: ./arcsight runcertutil -S -s “CN=host.arcsight.com” -v 6 -n mykey -k ec -q secp521r1 -x -t “C,C,C” -m 1234 -d /opt/arcsight/manager/config/jetty/nssdb When you import or generate a key pair into nssdb, if there is a existing key pair/certificate that has the same Common Name (CN) as the one you create, the runcertutil utility uses the alias of the existing key pair for the newly created key pair and ignores the alias you supplied in the runcertutil command line. • Make sure to use “mykey” (without quotes) as the alias name for the key pair as shown in the example. • The -m serial number should be unique within nssdb • The hostname is the short name or fully qualified domain name depending upon how your Manager name was set up when you installed the Manager. • Using -v to set the validity period of your certificate is optional. If you do not use this option, the certificate is valid for 3 months by default. If you choose to use it, see “Setting the Expiration Date of a Certificate” on page 180 section in the Administrator’s Guide for details. • The -q defines the PQG value with which an ECDSA certificate is generated.

Enter random keyboard strokes when prompted to generate the random seed used to generate your key. This generates a key pair and certificate with the alias mykey which is valid for 6 months from the current date and time in the Manager’s nssdb. b To check whether the key pair has been successfully created in the nssdb, run the following from the Manager’s <ARCSIGHT_HOME>/bin directory: ./arcsight runcertutil -L -d <ARCSIGHT_HOME>/config/jetty/nssdb Exporting the Manager’s Certificate To export the Manager’s certificate, run the following command from the Manager’s /opt/arcsight/manager/bin directory: ./arcsight runcertutil -L -n <certificate_alias> -r -d /opt/arcsight/manager/config/jetty/nssdb -o <absolute_path_to _managercertificatename.cert> For example, to export the certificate as a file named ManagerCert.cer to C:arcsightManager directory, run: ./arcsight runcertutil -L -n mykey -r -d /opt/arcsight/manager/config/jetty/nssdb -o /opt/arcsight/manager/ManagerCert.cer This generates the ManagerCert.cer file, the Manager’s certificate, in the /opt/arcsight/manager directory. Importing a Certificate into the Manager Import a certificate into the Manager: ./arcsight runcertutil -A -n <certificate_name> -t “CT,C,C” -d /opt/arcsight/manager/config/jetty/nssdb -i <absolute_path_to_the_root_certificate> For the -t option, be sure to use CT,C,C permissions flags only and in the same order that it is shown above. The -o specifies the absolute path to where you want to place the exported Manager’s certificate. If you do not specify the absolute path the file is exported to your /opt/arcsight/manager directory by default.

  • 9. Confidential Administrator’s Guide 9 Chapter 1 Basic Administration Tasks This chapter describes the various tasks that you can perform to effectively manage installation or perform additional configuration and maintenance operations for ArcSight Express components. The following topics are covered here: The Home Directory for Components on the Appliance The home directory, referred to as <ARCSIGHT_HOME> for each component on the ArcSight Express appliance is as follows: Manager: /opt/arcsight/manager CORR-Engine: /opt/arcsight/logger/current/arcsight/logger Web: /opt/arcsight/web Starting Components Start the Manager from a command or console window, or set up the Manager as a daemon. The remainder of this section provides more information about command line options you can use to start up, shut down, configure, or reconfigure ArcSight Express components. In addition, it provides information about setting up the Manager as a daemon, if you didn’t originally configure the Manager that way. “The Home Directory for Components on the Appliance” on page 9 “Starting Components” on page 9 “Reducing Impact of Anti-Virus Scanning” on page 11 “License Tracking and Auditing” on page 11 “Licensed EPS Compliance” on page 12 “ArcSight System Tasks” on page 13 “Setting up a Custom Login Banner” on page 13
  • 10. 1 Basic Administration Tasks 10 Administrator’s Guide Confidential Starting the ArcSight Manager To start the Manager from the command line, if it’s not configured to run either as a daemon or a service: Start the Manager by running the following command as user arcsight: /sbin/service arcsight_services start manager When you start the Manager as a service, to monitor whether it has successfully loaded, use the command: cd ARCSIGHT_HOME;tail -f logs/default/server.std.log Stopping the ArcSight Manager Stop the Manager service by running the following command as user arcsight: /sbin/service arcsight_services stop manager Starting the ArcSight Console To start up the ArcSight Console: 1 Open a command window or shell window on <ARCSIGHT_HOME>/bin. 2 Type in the following line and press Enter. ./arcsight console Reconnecting ArcSight Console to the Manager If the ArcSight Console loses its connection to the Manager—because the Manager was restarted, for example—a dialog box appears in the ArcSight Console stating that your connection to the Manager has been lost. Wait for the Manager to finish restarting, if applicable. Click Retry to re-establish a connection to the Manager or click Relogin. Starting ArcSight Web Access ArcSight Web through the Management Console. Starting the Management Console To start the console from a supported browser enter the following URL: https://<hostname>:8443/ Where <hostname> is the host name or IP address of the Manager that you specified when you first configured ArcSight Express. The connection to the Manager cannot be re-established while the Manager is restarting. In some cases, a connection cannot be established without resetting one or both machines. Clicking Retry may display connection exceptions while the Manager is restarting, or as the connection is re-established.
  • 11. 1 Basic Administration Tasks Confidential Administrator’s Guide 11 Starting ArcSight SmartConnectors This procedure is just for SmartConnectors that are not running as a service. If you are using the Connector Management feature to manage this connector, you probably do not need to use this command. It’s a good idea for the ArcSight Console to be running, so that you can see the status of the configured SmartConnectors and view messages as they appear on the Console. To start up an ArcSight SmartConnector: 1 Open a command window or terminal box and navigate to the connector’s /current/bin directory. 2 Type in the following line and press Enter: ./arcsight agents The connector in that folder starts. Starting Connector Management Services To start the Connector Management Service run the following command as user arcsight: /sbin/service arcsight_services start conapp To start the service for a connector container run the following command as user root: /sbin/service arcsight_services start connector_<N> ...where <N> is the number of the container whose service you want to start. Reducing Impact of Anti-Virus Scanning Files in certain directories are updated frequently; for example, the log directory. When an anti-virus application monitors these directories, it can impact the system in these ways:  It can place a large and constant load on the CPU of the machine.  It can slow the system down, because frequent scanning can impede writes to disk. Therefore, we recommend that you exclude the following directories (and any subdirectories under them) in <ARCSIGHT_HOME> from the virus scan list:  caches/server  logs  system  tmp  user, but include the user/agent/lib directory in the scan  archive License Tracking and Auditing The system automatically maintains a license audit history that allows you to see how many licenses are in use. When users log into the Console they receive a warning notifying them if they have exceeded their current license. ArcSight Express creates an internal
  • 12. 1 Basic Administration Tasks 12 Administrator’s Guide Confidential audit event for each licensable component to help users track which areas have been exceeded. There are licensing reports on individual features. These reports are located in /All Reports/ArcSight Administration/ESM/Licensing/. The reports provide a summary for the number of Actors, Assets, Users, Devices, and EPS identified over the last week. Licensed EPS Compliance By default, your events per second (EPS) throughput is monitored once every 24 hours and an average EPS value is calculated for that period. Your license places a limit on this average. It also places a limit on the number of times you are allowed to exceed the EPS limit over a period (rolling window) of days. In a given window, each time your EPS throughput exceeds the licensed limit, this violation is recorded. When the violations exceed the number allowed, your installation becomes noncompliant and you are temporarily prevented using certain functionality (as listed below). For Example:, suppose your license is set up as follows:  Number of incoming EPS allowed = 1000 EPS  Number of times allowed to exceed 1000 EPS = 5 times  Period over which you are allowed to exceed the 1000 EPS limit 5 times = 7 days If you exceed your maximum EPS limit (1,000) more than five times in seven days, punitive action starts. The punitive action is that access to the resources in the following list is disabled for an hour for every day you’ve exceeded the EPS limit in the seven day period, up to a maximum of five hours. It starts as soon as you exceed your limit. The EPS license compliance is enforced on the following viewers.  Channels (event and resource channels)  Data monitors  Query viewers and query viewers in dashboard  Pattern Discovery (creating new snapshots)  Event graph from channel  Global or Political Image Viewer in the Active Channel view  Category model view  Custom view Dashboards on the Console and ArcSight Web (but not the Management Console) Nothing happens to any of the above viewers if they already exist in viewer table when you exceed the License limit. However, if you attempt to create a new viewer, stop and restart a channel, create or edit a data monitor, and so on, you get an error message dialog that you have exceeded your license. In ArcSight Web only channels and dashboard are affected. As days continue to elapse, when the EPS limit violation is calculated to be five times or less in the past seven days, you become compliant and the features are automatically re-enabled.
  • 13. 1 Basic Administration Tasks Confidential Administrator’s Guide 13 ArcSight System Tasks These system tasks are scheduled to run automatically one or more times per day, depending on the task. You can control some of these schedules indirectly, for example by changing the retention period. AUP Updater: This task runs in the manager and pushes to connectors any updated AUP packages it might have. Dependent Resource Validator: This task runs validations on resources in the system and disables the ones that have problems. PurgeStaleMarkSimilarConfigs: This task does maintenance work on the 'mark similar' annotation criteria, removing the ones that are stale. Resource Search Index Updater: This task updates the resource search index. Sortable Fields Updater: This task keeps sortable event fields in sync, based on the current indices in the database. Table Stats Updator: This task updates statistics on the non-partitioned schema tables, which includes the resource tables. Setting up a Custom Login Banner You can configure the Manager to return a custom login message to display for users logging in to the ArcSight Console. Set the following property in server.properties: auth.login.banner=config/loginbanner.txt This property configures the Manager to send the text from the file <ARCSIGHT_HOME>/config/loginbanner.txt whenever a user runs the ArcSight Console. (Changes to the properties file take effect the next time the Manager is started.) Create a text file named loginbanner.txt in the <ARCSIGHT_HOME>/config directory. This feature is often used to display a legal disclaimer message. Users must close the message window before they can log in.

  • 15. Confidential Administrator’s Guide 15 Chapter 2 Configuration This chapter describes the various tasks that you can perform to manage the component configuration. The following topics are covered in this chapter: Managing and Changing Properties File Settings Various components use properties files for configuration. Many sections of this documentation require you to change properties in those files. Some of the properties files are also modified when you use one of the configuration wizards. Property File Format Generally, all properties files are text files containing pairs of keys and values. The keys determine which setting is configured and the value determines the configuration value. For example, the following property configures the port on which the Manager listens: servletcontainer.jetty311.encrypted.port=8443 Blank lines in this file are ignored as well as lines that start with a pound sign ( # ). Lines that start with a pound sign are used for comments. “Managing and Changing Properties File Settings” on page 15 “Adjusting Console Memory” on page 21 “Adjusting Pattern Discovery Memory” on page 21 “Installing New License Files Obtained from HP” on page 21 “Configuring Manager Logging” on page 22 “Understanding SSL Authentication” on page 31 “Reconfiguring the ArcSight Console after Installation” on page 72 “Reconfiguring Connectors” on page 72 “Reconfiguring ArcSight Manager” on page 72 “Managing Password Configuration” on page 73 “Advanced Configuration for Asset Auto-Creation” on page 78 “Compression and Turbo Modes” on page 81 “Sending Events as SNMP Traps” on page 82 “Asset Aging” on page 84 “Configuring Actors” on page 86
  • 16. 2 Configuration 16 Administrator’s Guide Confidential Defaults and User Properties Most configuration items in various components consist of at least two files. The first, is the defaults properties file, such as server.defaults.properties. It contains the default settings. You shoule not modify these files; use them as a reference. The second file, is the user properties file, such as server.properties. It can contain any properties from the defaults properties file, but the property values in this file override those in the defaults file. Thus, it contains settings that are specific to a particular installation. Typically, the user properties file for a component is created and modified automatically when you configure the component using its configuration wizard. Because the user properties file contains settings you specify to suit your environment, it is never replaced by an upgrade. If an upgrade, such as a service pack or a version update, changes any properties, it does so in the defaults file. The following table lists the most important properties files. For information on Connector Management properties files (container and connector properties), refer to the Connector ManagementUser’s Guide. Editing Properties Files When you edit a *.properties file, first look for the *.defaults.properties file. Copy the property you want to edit from *.defaults.properties to *.properties and change the setting to your new value in *.properties. When the same property is defined differently in each file, the system uses the value in *.properties. This ensures that when you install an upgrade, and the *.defaults.properties file is updated, the properties you customized are retained unchanged in *.properties. You can edit the properties using any simple text editor, such as Notepad, on Windows. Make sure you use one that does not add any characters such as formatting codes. If you configured the Console and SmartConnectors using default settings in the configuration wizard, a user properties file is not created automatically for that component. If you need to override a setting on such a component, use a text editor to create this file in the directory specified in the above table. When you edit a property on a component, you must restart the component for the new values to take effect except for the dynamic Manager properties listed in the next section. If you change a communication port, be sure to change both sides of the connection. For example, if you configure a Manager to listen to a different port than 8443, be sure to Default Properties User Properties Purpose config/server.defaults. properties config/server.properties Manager Configuration config/console.defaults. properties config/console.properties ArcSight Console Configuration config/client.defaults. properties config/client.properties ArcSight Common Client Config config/agent/agent. defaults.properties user/agent/agent.properties SmartConnector Configuration
  • 17. 2 Configuration Confidential Administrator’s Guide 17 configure all the Manager’s clients (Consoles, SmartConnectors, ArcSight Web, and so on) to use the new port as well. Dynamic Properties When you change the following properties in the server.properties file on the Manager, you do not need to restart the Manager for the changes to take effect:  auth.auto.reenable.time  auth.enforce.single.sessions.console  auth.enforce.single.sessions.web  auth.failed.max  auth.password.age  auth.password.age.exclude  auth.password.different.min  auth.password.length.max  auth.password.length.min  auth.password.letters.max Protocol Port Configuration ICMP none ArcSight Console to Target communication (ping tool) UDP 1645 or 1812 Manager to RADIUS server (if enabled) TCP 9443 ArcSight Web 9090 ESM Service Layer Container Port 9002 Remote Connector Management listening port 9001 Remote Connector Management listening port TCP 8443 Management Console and ArcSight Console to Manager communication TCP 8443 SmartConnector to Manager communication TCP 6443 Connector Management TCP 636 Manager to LDAP server (w/ SSL if enabled)* TCP 389 Manager to LDAP server (w/o SSL if enabled)* TCP 143 Manager to IMAP server (for Notifications) TCP 110 Manager to POP3 server (for Notifications) UDP/TCP 53 ArcSight Console to DNS Server communication (nslookup tool) UDP/TCP 43 ArcSight Console to Whois Server communication (whois tool) TCP 25 Manager to SMTP server (for Notifications)

Every time the manager-reload-config command is successful, a copy of the server.properties file it loaded is placed in <ARCSIGHT_HOME>/config/history for backup purposes. The server.properties file in <ARCSIGHT_HOME>/config/history is suffixed with a timestamp and does not overwrite the existing versions, as described in the following example. Example Manager M1 starts successfully for the first time on September 26, 2012, at 2:45 p.m. A backup copy of its server.properties file is written to <ARCSIGHT_HOME>/config/history with this timestamp: server.properties.2012_09_26_14_45_27_718 On September 27, 2010, the M1 administrator adds the following property to the server.properties file: notification.aggregation.max_notifications=150 When the administrator runs the manager-reload-config command at 1:05 p.m. the same day, it runs successfully because this property can be loaded dynamically. As soon as the updated server.properties file is loaded in M1’s memory, a backup copy of the updated server.properties file is written to <ARCSIGHT_HOME>/config/history with appropriate timestamp. Now, <ARCSIGHT_HOME>/config/history contains these two backup files:
  • 19. 2 Configuration Confidential Administrator’s Guide 19 server.properties.2012_09_26_14_45_27_718 server.properties.2012_09_27_01_05_40_615 On September 28, 2012, the M1 administrator adds this property to the server.properties file: notification.aggregation.time_window=2d As this property can be also loaded dynamically, similar to the previous change, once the updated server.properties is loaded in M1’s memory, a backup copy of the server.properties file is written to <ARCSIGHT_HOME>/config/history with appropriate timestamp. Now, <ARCSIGHT_HOME>/config/history contains these three backup files: server.properties.2012_09_26_14_45_27_718 server.properties.2012_09_27_01_05_40_615 server.properties.2012_09_28_03_25_45_312 On September 39, 2012, the M1 administrator updates the whine.notify.emails property in the server.properties file. When he runs the manager-reload-config command, the command fails because this property cannot be loaded dynamically. As a result, these things happen:  The updated server.properties file is not loaded into M1’s memory, however, changes made to it are not reverted.  M1 continues to use the properties that were loaded on September 29th.  No backup copy is made. The <ARCSIGHT_HOME>/config/history directory continues to contain the same three backup files: server.properties.2012_09_26_14_45_27_718 server.properties.2012_09_27_01_05_40_615 server.properties.2012_09_28_03_25_45_312 The changes made on September 30th are not effective until M1 is restarted. Changing Manager Properties Dynamically To change any of the properties listed previously, do these steps: 1 Change the property in the server.properties file and save the file. 2 (Optional) Use the –diff option of the manager-reload-config command to view the difference between the server properties the Manager is currently using and the properties loaded after you run this command: arcsight manager-reload-config –diff 3 Run this command in <ARCSIGHT_HOME>/bin to load the new values for the properties you changed: The -diff option compares all server properties—default and user properties. For all options available with the manager-reload-config command, see Appendix A‚ Administrative Commands‚ on page 105.
  • 20. 2 Configuration 20 Administrator’s Guide Confidential arcsight manager-reload-config If this command fails with a warning, it indicates that you are changing properties that require a Manager restart before those changes can take effect. When you get such a warning none of the property changes, including the ones that can be reloaded without restarting the Manager, are applied. You can do one of the following in this situation:  Revert changes to properties that cannot be loaded without restarting the Manager and rerun the manager-reload-config command.  Force an update of all properties using the –as option, as follows: arcsight manager-reload-config -as When you use the -as option, the properties that can be changed without restarting the Manager take effect immediately. The properties that require a Manager restart are updated in the server.properties but are not effective until the Manager is restarted. For example, if you change auth.password.length.min to 7 and search.enabled to false, you get the above warning because only auth.password.length.min can be updated without restarting the Manager. If you force an update of the server.properties file, auth.password.length.min is set to 7, but search.enabled continues to be set to true until the Manager is restarted. Changing the Service Layer Container Port By default the service layer container port is 9090. You can change this port: 1 Modifying the following files located in the Manager’s <ARCSIGHT_HOME>:  /arcsight-dm com.arcsight.dm.plugins.tomcatServer_7.0.21/conf/server.xml  /config/proxy.rule.xml  /config/rewriteProxy.rule.xml Make sure to replace the references to port 9090 with an unused port number. 2 Restart the Manager. Securing the Manager Properties File The Manager’s server.properties file contains sensitive information such as database passwords, keystore passwords, and so on. Someone accessing the information in this file can do a number of things, such as tampering with the database and acting as a Manager. As a result, the server.properties file must be protected so that only the user account under which the Manager is running is able to read it. For example, in Unix you can use the chmod command: chmod 600 server.properties This operation is performed during the Manager installation. As a result, only the owner of the file (which must be the user that runs the Manager) may read or write to the file. For all other users, access to the file is denied. Be careful in using the –as option to force reload properties. If an invalid static change is made, it may prevent the Manager from starting up once it reboots.
  • 21. 2 Configuration Confidential Administrator’s Guide 21 Adjusting Console Memory Because the ArcSight Console can open up to ten independent event-viewing channels, out-of-memory errors may occur. If such errors occur, or if you simply anticipate using numerous channels for operations or analysis, please make the following change to each affected Console installation. In the bin/scripts directory, in the console.sh configuration file, edit the memory usage range for the Java Virtual Machine. Adjusting Pattern Discovery Memory By default, Pattern Discovery limits its memory usage to about 4 GB of memory. However, if the search for patterns involves too many transactions and events, the task can run out of memory and abort. You can control the memory limit indirectly by changing the maximum number of transactions and events the Pattern Discovery task can hold in memory. The settings for these values are in the server.defaults.properties file in the config folder.  patterns.transactionbase.max — The maximum number of transactions allowed in memory. If you exceed this number, these transactions are stored as page file. The default is 10000.  patterns.maxSupporterCost — The maximum number of supporters allowed in memory. If you exceed this number, the Pattern Discovery task aborts. The default is 80000.  patterns.maxUniqueEvents — The maximum number of unique events allowed in memory. If you exceed this number, the Pattern Discovery task aborts. The default is 20000. If the Pattern Discovery task aborts, a message to that effect appears in the console. Run the Pattern Discovery task again after increasing the Pattern Discovery memory usage limits. You can increase the memory usage limit by increasing the three values proportionally. For example, to add 25 percent more memory capacity, you would change the values to:  patterns.transactionbase.max=12500  patterns.maxSupporterCost=100000  patterns.maxUniqueEvents=25000 You can edit the properties file using a regular text editor. After changing any of these values, restart the manager for them to take effect.

  • 22. 2 Configuration 22 Administrator’s Guide Confidential 4 After uploading, the Management Console asks you if you want to Restart, which restarts certain ArcSight server processes. You can choose to restart later. If so, when you are ready, select Server Management in the accordion panel under Configuration Management, and click Restart, at the bottom. You will have to log in again. If you are using ArcSight Express on an appliance, restart the Manager by running the appropriate command, as describe in “ArcSight_Services Command” on page 106. Configuring Manager Logging The Manager outputs various types of information to log files. By default, the logs are located in: <ARCSIGHT_HOME>/logs/default/ Various Manager utilities write logging information to different sets of log files. Each of those sets can consist of multiple files. The number and size of the log files are configurable, a typical setting is 10 files with 10 megabytes each. When a log file reaches a maximum size, it is copied over to a different location. Depending on your system load, you may have to change the default settings. To make changes to the logging configuration, change the log channel parameters. The default log channel is called file. For the main Manager log file, called server.log, the following server.properties settings are used: # Maximum size of a log file. log.channel.file.property.maxsize=10MB # Maximum number of roll over files. log.channel.file.property.maxbackupindex=10 The first setting affects the size of each individual log file; the second setting affects the number of log files created. The log file currently in use is always the log file with no number appended to the name. The log file with the largest number in its extension is always the oldest log file. All of the log files are written to the <ARCSIGHT_HOME>/logs/default directory. The Manager and its related tools write the following log files: Description server.log* The main Manager log. server.status.log* System status information, such as memory usage etc. server.channel.log* Active Channel logs. server.std.log* All output that the Manager prints on the console (if run in command line mode) server.pulse.log* The Manager writes a line to this set of logs every ten seconds. Used to detect service interruptions.
  • 23. 2 Configuration Confidential Administrator’s Guide 23 For information on Connector Management logs, refer to the Connector Management User’s Guide. Sending logs and diagnostics to HP Support Customer Support may request log files and other diagnostic information to troubleshoot problems. The Send Logs utility automatically locates the log files and compresses them. You can send the compressed files to Customer Support.  You can run this utility as a wizard directly from the Console interface (GUI) in addition to the command-line interface of each component.  Optionally, gather diagnostic information such as session wait times, thread dumps, and database alert logs about your ArcSight Express system, which helps HP Customer Support analyze performance issues on your ArcSight Express components.  When you run this utility from the Console, Manager, or Web, you can gather logs and diagnostic information for all components of the system. Guidelines for using the Send Logs utility Keep these guidelines in mind when using the Send Logs utility:  You can be connected as any valid user on an ArcSight Express component to collect its local logs; however, you must have administrator access to collect logs from other components. For example, if you are connected as user ‘joe’ to the Console, you can collect its logs. But if you need to collect logs for the Manager and the database, you must connect to the Console as the administrator.  SmartConnectors must be running version 4037 or later to remotely (using a Console or the Manager) collect logs from them.  You can only collect local logs on SmartConnectors or the CORR-Engine . The Send Logs utility only collects logs for the component on which you run it. In order to collect the CORR-Engine logs, the Manager needs to be running.  You can run the Send Logs utility on a component that is down. That is, if the Database is down, you can still collect its logs using this utility. If the Manager is down, you can only collect its local logs. However, if you need to collect the database logs as well, use the arcdt command on the Manager. For more information, see Appendix A‚ Administrative Commands‚ on page 105.  All log files for a component are gathered and compressed. That is, you cannot select a subset of log files that the utility should process. server.sql.log* If database tracing is enabled, the SQL statements are written to this set of log files. execproc.log* Log information about externally executed processes (only on some platforms) serverwizard.log* Logging information from the arcsight managersetup utility. You can also use the arcdt command to run specific diagnostic utilities from the Manager command line. For more information, see Appendix A‚ Administrative Commands‚ on page 105. Description
  • 24. 2 Configuration 24 Administrator’s Guide Confidential  The Send Logs utility generates a compressed file on your local system that you can send to Customer Support by e-mail, if they request it.  You can review the compressed file to ensure that only a desired and appropriate amount of information is sent to support.  You can remove or sanitize information such as IP addresses, host names, and e-mail addresses from the log files before compressing them. The options are:  Send log as generated This option, the default, does not remove any information from the logs files.  Only remove IP address This option removes IP addresses, but not host names or e-mail addresses, from the logs files.  Remove IP address, host names, e-mail addresses This option removes all IP addresses and enables you to specify a list of host- name suffixes for which all host names and e-mail addresses are removed from the logs. For example, if you specify ‘company.com’ as a host-name suffix to remove, the Send Logs utility removes all references to domains such as ‘www.company.com’ and e-mail addresses such as ‘john@company.com’ from the logs. Gathering logs and diagnostic information When you run the Send Logs utility on SmartConnectors, it gathers logs and diagnostic information (if applicable) for only those components. However, when you run this utility on ArcSight Console, Manager, or ArcSight Web, you can gather logs and diagnostic information for all or a selected set of ArcSight Express components. To run this utility on SmartConnectors, enter this in <ARCSIGHT_HOME>/bin: ./arcsight agent sendlogs To gather logs and diagnostic information for all or a selected set of components, do one of the following:  On the ArcSight Console, click Tools > SendLogs.  Enter this command in <ARCSIGHT_HOME>/bin on Console, Manager, or Web: ./arcsight sendlogs The above action starts the Send Logs wizard. In the wizard screens, perform these steps: The Send Logs wizard remembers most of the choices you make when you run it for the first time. Therefore, for subsequent runs, if you choose to use the previous settings, you do not need to re-enter them.

  • 31. 2 Configuration Confidential Administrator’s Guide 31 5 Click Finish in the last screen. Understanding SSL Authentication Secure Socket Layer (SSL) technology is used for communication between the Manager and its clients—Console, SmartConnectors, and ArcSight Web. SSL is also used between ArcSight Web and the web browsers that communicate with it. SSL enables the Manager (referred to as a “server”) to authenticate to its clients and communicate information over an encrypted channel, thus providing the following benefits:  Authentication—Ensuring that clients send information to an authentic server and not to a machine pretending to be that server.  Encryption—Encrypting information sent between the clients and the server.  Data Integrity—Hashing information to prevent intentional or accidental modification. By default, clients submit a valid user name and password to authenticate with the server; however, these clients can be configured to use SSL client authentication. Note that SSL is not used between the Manager and the Database.
  • 32. 2 Configuration 32 Administrator’s Guide Confidential Terminology These terms are used in describing and configuring SSL:  Certificate A certificate contains the public key, identifying information about the machine such as machine name, and the authority that signs the certificate. SSL certificates are defined in the ISO X.509 standard.  Key pair A key pair is a combination of a private key and the public key that encrypts and decrypts information. A machine shares only its public key with other machines; the private key is never shared. The public and private keys are used to set up an SSL session. For details, see “How SSL Works” on page 42.  SSL server-SSL client An SSL session is set up between two machines—a server and a client. Typically, a server must authenticate to its clients before they send any data. However, in client- side SSL authentication, the server and its clients authenticate each other before communicating. The Manager is an SSL server, while SmartConnectors, Console, and browsers are SSL clients. ArcSight Web is an SSL client to the Manager and an SSL server to the web browsers that connect to it.  Keystore A keystore is an encrypted repository on the SSL server that holds the SSL certificate and the server’s private key. The following table lists the ArcSight Express component, the name of the keystore on that component, and its location. [1] When client-side authentication is used, a keystore exists on both the server and the client. [2] Make sure you do not change the keystore file name. The keytoolgui utility, used to perform a number of SSL configuration tasks, refers to a combination of an SSL certificate and private key as the key pair. The keytoolgui utility is discussed in “Tools for SSL Configuration” on page 36. Log File keystore File Name[2] Location of keystore Manager keystore <ARCSIGHT_HOME>/config/jetty ArcSight Web webkeystore <ARCSIGHT_HOME>/config/jetty Clients[1] (for client-side authentication) keystore.client <ARCSIGHT_HOME>/config
  • 33. 2 Configuration Confidential Administrator’s Guide 33  Truststore Truststore is an encrypted repository on SSL clients that contains a list of certificates of the issuers that a client trusts. When an issuer issues a certificate to the server, it signs the certificate with its private key. When the server presents this certificate to the client, the client uses the issuer’s public key from the certificate in its truststore to verify the signature. If the signature matches, the client accepts the certificate. For more details, see how SSL handshake occurs in “How SSL Works” on page 42. The following table lists the ArcSight Express component, the name of the truststore on that component, and its location. [1] The utilities that exist on the Manager machine such as archive are treated as clients of the Manager. The cacerts file on the Manager is used for authenticating the Manager to these clients. [2] When client-side authentication is used. [3] When client-side authentication is used, ArcSight Web contains two truststores— cacerts for connections to the Manager and webtruststore for connections to browsers. The keytoolgui utility, used to view a truststore, is discussed in “Tools for SSL Configuration” on page 36.

  • 34. 2 Configuration 34 Administrator’s Guide Confidential  Alias Certificates and key pairs in a keystore or a truststore are identified by an alias.  Truststore password The *.defaults.properties file contains the default truststore password for each ArcSight Express component (changeit). The password is in clear text and typically, you do not need to change it. To change or obfuscate it, use the changepassword utility, as described in Appendix A‚ Administrative Commands‚ on page 105. The following table lists the property name where the obfuscated truststore passwords are stored. *For client-side authentication ** If config/client.properties or user/agent/agent.properties does not exist, create it using an editor of your choice.  Keystore password Use a keystore password to encrypt the keystore file and use a truststore password to encrypt a truststore file. Without this password, you cannot open these files. The default is password for the Manager and ArcSight Web, and changeit for the ArcSight Console’s client keystore. The default password for the key pair for any component is the same as for the component’s keystore. You specify a keystore password when creating a key pair, which is discussed in later sections of this chapter. The password is obfuscated and stored in the ArcSight Express component’s *.properties file. The following table lists the property file Truststore Property File Property Name Client client.properties** ssl.truststore.password Manager* server.properties servletcontainer.jetty311.truststore .password.encrypted ArcSight Web webserver.properties servletcontainer.jetty311.truststore .password.encrypted Connector agent.properties** ssl.truststore.password

The following table lists the property name where the obfuscated keystore passwords are stored. *For client-side authentication ** If config/client.properties or user/agent/agent.properties does not exist, create it using an editor of your choice.  NSS database password The default password for the Manager’s nssdb, the Console’s nssdb.client, and ArcSight Web’s webnssdb are all changeit. To change it, see “Changing the Password for NSS DB” on page 178.  Cacerts password The default password for cacerts ischangeit.  Cipher suite A set of authentication, encryption, and data integrity algorithms used for securely exchanging data between an SSL server and a client. The following cipher suites are enabled by default:  TLS_RSA_WITH_AES_128_CBC_SHA  SSL_RSA_WITH_3DES_EDE_CBC_SHA  SSL_RSA_WITH_RC4_128_MD5  SSL_RSA_WITH_RC4_128_SHA Other supported cipher suites are:  TLS_DHE_RSA_WITH_AES_128_CBC_SHA  TLS_DHE_DSS_WITH_AES_128_CBC_SHA  SSL_DHE_RSA_WITH_3DES_EDE_CBC_SHA  SSL_DHE_DSS_WITH_3DES_EDE_CBC_SHA  SSL_RSA_WITH_DES_CBC_SHA  SSL_DHE_RSA_WITH_DES_CBC_SHA  SSL_DHE_DSS_WITH_DES_CBC_SHA  SSL_RSA_EXPORT_WITH_RC4_40_MD5  SSL_RSA_EXPORT_WITH_DES40_CBC_SHA  SSL_DHE_RSA_EXPORT_WITH_DES40_CBC_SHA  SSL_DHE_DSS_EXPORT_WITH_DES40_CBC_SHA  SSL_RSA_WITH_NULL_MD5  SSL_RSA_WITH_NULL_SHA Keystore Property File Property Name Client* client.properties** ssl.keystore.password.encrypted Manager server.properties server.privatekey.password.encrypted ArcSight Web webserver.properties server.privatekey.password.encrypted Connector agent.properties** ssl.keystore.password.encrypted

During the SSL handshake, the client provides this list as the cipher suites that it can accept, in descending order of preference. The server compares the list with its own set of acceptable cipher suites, picks one to use based on its order of preference, and communicates it to the client. Tools for SSL Configuration Keytoolgui The keytoolgui utility enables you to perform a number of SSL configuration tasks on Windows. Some of these tasks are:  “Using Keytoolgui to Export a Key Pair” on page 36  “Using Keytoolgui to Import a Key Pair” on page 37  “Using Keytoolgui to Export a Certificate” on page 37  “Using Keytoolgui to Import a Certificate” on page 38  “Creating a keystore Using Keytoolgui” on page 40  “Generating a Key Pair Using Keytoolgui” on page 40  For information about managing certificates on a Connector Management container, refer to the Connector Management User’s Guide.

  • 41. 2 Configuration Confidential Administrator’s Guide 41 keytool The keytool utility is the command-line version of keytoolgui that you can use to manipulate the keystores and truststores directly. Use the keytool utility on UNIX environments without X11 or whenever a command-line option is more suitable. Use keytool -help for a complete list of all command options and their arguments. To use keytool, enter this command: arcsight keytool [option] –store <store value> where <store value> can be:  managerkeys—Manager keystore  managercerts—Manager truststore  webkeys—Web keystore  webcerts—Web truststore  ldapkeys—Manager LDAP Client keystore  ldapcerts—Manager LDAP Client truststore  clientkeys—Client keystore  clientcerts—Client truststore On SmartConnector hosts, use: arcsight agent keytool [option] –store <store value> The following is an example for creating a 2048-bit, RSA key-pair with the mykey alias that expires in 10 years (3650 days). arcsight keytool -v -genkeypair -alias mykey -validity 3650 -keyalg rsa -keysize 2048 -store managerkeys The following is an example for exporting the above key-pair as a "self-signed" RFC-1421 compliant ASCII certificate. arcsight keytool -exportcert -alias mykey -v -store managerkeys -rfc -file export_mykey.pem You can also SCP your keystore file to a computer where the ArcSight Console is installed and use keytoolgui to make changes before uploading back to the remote server. tempca The tempca utility enables you to manage the SSL certificate in many ways. To see a complete list of parameters available for this utility, enter this in <ARCSIGHT_HOME>/bin: ./arcsight tempca On SmartConnectors, use: ./arcsight agent tempca Two frequently performed operations using this utility are:  Viewing the type of certificate in use on the Manager:
  • 42. 2 Configuration 42 Administrator’s Guide Confidential ./arcsight tempca –i  Removing the Demo certificate from the list of trusted certificates, if applicable: ./arcsight tempca -rc How SSL Works When a client initiates communication with the SSL server, the server sends its certificate to authenticate itself to the client. The client validates the certificate by verifying:  The hostname is identical to the one with which the client initiated communication.  The certificate issuer is in the list of trusted certificate authorities in the client’s truststore (<ARCSIGHT_HOME>/jre/lib/security/cacerts) and the client is able to verify the signature on the certificate by using the CA’s public key from the certificate in its truststore.  The current time on the client machine is within the validity range specified in the certificate to ensure that the certificate is valid. If the certificate is validated, the client generates a random session key, encrypts it using the server’s public key, and sends it to the server. The server decrypts the session key using its private key. This session key is used to encrypt and decrypt data exchanged between the server and the client from this point forward.
  • 43. 2 Configuration Confidential Administrator’s Guide 43 The following figure illustrates the handshake that occurs between the client and Manager. With client-side authentication, the server requests the client’s certificate when it sends its certificate to the client. The client sends its certificate along with the encrypted session key. SSL certificates To replace an expired certificate, delete the expired certificate from the truststore, cacerts, first and then import the new certificate into cacerts. Since the common name (CN) for the new certificate is identical to the CN in the old certificate, you are not permitted have both the expired and the new certificate in the cacerts. To delete a certificate from the truststore, start the keytoolgui and navigate to the certificate, right-click on the certificate, and select Delete. Use the keytoolgui to import the new certificate into the truststore or cacerts. Types You can use three types of SSL certificates:  CA-signed
  • 44. 2 Configuration 44 Administrator’s Guide Confidential  Self-signed (applicable to default mode only)  Demo (applicable to default mode only) CA-signed certificates are issued by a third party you trust. The third party may be a commercial Certificate Authority (CA) such as VeriSign and Thawte or you might have designated your own CA. Because you trust this third party, your clients’ truststores might already be configured to accept its certificate. Therefore, you may not have to do any configuration on the client side. The process to obtain a CA-signed certificate is described in “Create a Key Pair for a CA-Signed Certificate” on page 49. You can create your own self-signed certificates. A self-signed certificate is signed using the private key from the certificate itself. Configure clients to trust each self-signed certificate you create. Comparing Self-signed and CA-signed certificates Self-signed certificates are as secure as CA-signed, however, CA-signed certificates scale better as illustrated in this example: If you have three SSL servers that use self-signed certificates, configure your clients to accept certificates from all of them (the three servers are three unique issuers). If you add a new server, configure clients again. However, if these servers use a CA-signed certificate, configure the clients once to accept the certificate. If the number of Managers grows in the future, you do not need to do any additional configuration on the clients. Viewing Certificate Information For certificates in the keystore, truststore, or cacerts, use the keytoolgui command to see certificate information. For the nssdb, nssdb.client, and webnssdb, usethe runcertutil command to view certificate information. See “runcertutil” on page 134, for more information. For the Manager certificate you can also use tempca -i command. ArcSight WebUsing a Self-Signed Certificate The procedure you follow depends on the number of Managers with which your clients communicate. For information about managing certificates on a Connector Management container, refer to the Connector Management User’s Guide. When clients communicate with one Manager To use a self-signed certificate for deployments in which clients communicate with only one Manager, perform these steps: 1 On the Manager, create a self-signed key pair: a In <ARCSIGHT_HOME>/bin, run this command: ./arcsight managersetup Steps to create a self-signed key pair may be different for a new Manager installation as the Configuration Wizard is launched automatically during the installation process.

Click Next. d Enter the SSL keystore password for the certificate. Click Next.
  • 46. 2 Configuration 46 Administrator’s Guide Confidential Remember this password. You use it to open the keystore. e Step through the Configuration Wizard. At the end of the Configuration Wizard, these three things happen: i The Manager’s keystore, <ARCSIGHT_HOME>/config/jetty/keystore, is replaced with the one created using this procedure. ii A selfsigned.cer certificate file is generated in the <ARCSIGHT_HOME>/config/jetty directory. iii The newly generated self-signed certificate is added to the Manager’s truststore file, <ARCSIGHT_HOME>/jre/lib/security/cacerts. 2 Export the Manager’s certificate from <ARCSIGHT_HOME>/jre/lib/security/cacerts. 3 Make sure to copy the Manager’s certificate to each machine from which clients connect to the Manager. 4 Import the Manager’s certificate to the <ARCSIGHT_HOME>/jre/lib/security directory on all clients. See “Using Keytoolgui to Import a Certificate” on page 38. 5 Restart the Manager process so that the Manager can start using the self-signed certificate. Run the following command to do so: The self-signed certificate does not take effect until the Manager is restarted later in this procedure. This step overwrites your existing cacerts with the new one that contains the information about the Trusted Certificate Authority (CA) that signed your self-signed certificate. However, the new cacerts file does not take effect until the client is restarted later in this procedure. Make sure you have imported the Manager’s certificate to all existing clients before proceeding further. Otherwise, after you perform the next steps, only clients with the new Manager’s certificate can connect to the Manager.
  • 47. 2 Configuration Confidential Administrator’s Guide 47 /sbin/service arcsight_services restart manager 6 Restart all clients. 7 When installing a new client, repeat Steps 2-4 of this procedure. 8 On the ArcSight Web server, perform the steps listed in section “Setting up SSL Client Authentication on ArcSight Web” on page 62. 9 On the ArcSight Console, perform the steps listed in section “Setting up SSL Client-Side Authentication on ArcSight Console” on page 55. When clients communicate with multiple Managers To use self-signed certificate for a deployment in which clients communicate with more than one Managers, perform these steps for each Manager: 1 Follow Step 1 from the previous procedure on all Managers. 2 Copy the selfsigned.cer file from all Managers to the <ARCSIGHT_HOME>/jre/lib/security directory on one of your clients. To prevent a certificate file from overwriting another when you copy multiple certificate files with the same name to the same location, rename each certificate file as you copy. For example, copy the certificate file from ManagerA and rename it to SelfSigned_MgrA.cer. 3 On that client, use the keytoolgui utility to import certificates into the truststore (cacerts): a In <ARCSIGHT_HOME>/bin, run this command: ./arcsight keytoolgui b Click File->Open keystore. c In <ARCSIGHT_HOME>/jre/lib/security, select the store named cacerts. For the default password see “Cacerts password” on page 35. d Click Tools->Import Trusted Certificate: i Select the self-signed certificate for a Manager and click Import. ii You see the following message. Click OK. The Certificate details are displayed. Click OK. By following this procedure you append the self-signed certificate to the existing client truststore, cacerts. Doing so prevents overwriting cacerts, which happens if you follow the previous procedure.

Typically, the alias Name is same as the fully qualified host name. v You see the following message. Click OK. vi Save the truststore file. vii Repeat Steps i through vi for all self-signed certificates you copied. e On the client, enter this command in <ARCSIGHT_HOME>/bin to stop the client from using the currently in-use Demo certificate: ./arcsight tempca -rc For SmartConnectors, run: ./arcsight agent tempca –rc 4 Repeat this cacerts procedure on all other clients. 5 Restart the Manager service so that the Manager can start using the self-signed certificate. 6 Restart the client. 7 When installing a new client, copy the cacerts file from any client you updated earlier in this procedure. Using a CA-Signed SSL Certificate Using certificate signed by a Certificate Authority means replacing your demo or self-signed certificate. You should obtain two CA-signed certificates—one for the Manager and the other for ArcSight Web, unless both components are installed on the same machine. Follow the procedure described in this section to obtain and import the certificates to the Manager, and if appropriate, to ArcSight Web.
  • 49. 2 Configuration Confidential Administrator’s Guide 49 For information about managing certificates on a Connector Management container, refer to the Connector Management User’s Guide. Obtaining and deploying a CA-signed certificate involves these steps: 1 Create a Key Pair for a CA-Signed Certificate. 2 Send for the CA-Signed Certificate. 3 Import the CA Root Certificate. 4 Import the CA-Signed Certificate. 5 Restart the Manager. 6 Accommodating Additional Components. Create a Key Pair for a CA-Signed Certificate To Create a key pair: 1 On the Manager machine, run this command to launch the keytoolgui utility in <ARCSIGHT_HOME>/bin: ./arcsight keytoolgui 2 Click File->New keystore to create a new keystore. 3 Select JKS for the keystore Type, it supports Java keystore: 4 Click Tools->Generate Key Pair to create the key pair. This can take some time. 5 Enter key pair information such as the length of time for its validity (in days). Click OK. For Common Name (CN), enter the fully qualified domain name of the Manager. Ensure that DNS servers, used by the clients connecting to this host, can resolve this host name. For Email(E), provide a valid e-mail address as the CAs typically send an e-mail to this address to renew the certificate. When you click OK it asks you for a new password. Use the password of your existing keystore to save this keystore. Also, the Manager may fail to start if the password of the Key pair does not match the password of the keystore, which is encrypted in server.properties. If you do not remember the password, run the Manager setup Wizard and change the password of your existing keystore before you proceed. You reuse this file after receiving the reply from the CA. 6 Specify an alias name of mykey for referring to the new key pair.
  • 50. 2 Configuration 50 Administrator’s Guide Confidential 7 Click File->Save as and save the keystore with a name such as keystore.request. For ArcSight Web, save the file with a name such as webkeystore.request. Send for the CA-Signed Certificate To send for the CA-signed certificate, first create a certificate signing request (CSR). 1 In the keytoolgui utility, right-click the mykey alias name and select Generate CSR to create a Certificate Signing Request. 2 Choose a path and filename, and click Generate. After you enter a file name, the CSR file is generated in the current working directory. 3 Send the CSR to the selected Certificate Authority (CA). After verifying the information you send, the CA electronically signs the certificate using its private key and replies with a certification response that contains the signed certificate. Import the CA Root Certificate When you get the response from the certificate authority, it should include instructions for getting the root CA certificate. You can skip this step if renewing a CA-signed certificate issued by the same root certificate authority. You import the CA root certificate into the truststore file. 1 Save the Root CA certificate as a file rootca.cer. 2 Repeat the following procedure on all the machines where the Manager is installed: a Launch the keytoolgui utility on the Manager machine. b Click File > Open keystore. c Select the Truststore file located at <ARCSIGHT_HOME>/jre/lib/security/cacerts. Use the default password to open cacerts. For the default password see “Cacerts password” on page 35. d Click Tools >Import Trusted Certificate, and pick the rootca.cer file. e You see the following warning message: “Could not establish a trust path for the certificate. The certificate information will now be displayed after which you may confirm whether or not you trust the certificate.” f Click OK to finish. • If the CA root certificate has a chain, follow the same procedure to import all intermediate CA certificates into the Truststore. • Update the CA root certificate on other ArcSight Express components, as well. - Repeat step 2 on one of Consoles. - Copy the updated cacerts to any Logger or Connector Appliance, and other PCs that have installed Consoles, Connectors, or ArcSight Web. • Restart all services after the new cacerts is copied.
  • 51. 2 Configuration Confidential Administrator’s Guide 51 Import the CA-Signed Certificate When the CA has processed your request, it sends you a file with the signed certificate. You import this certificate into the Manager’s keystore. The SSL certificate you receive from the Certificate Authority must be a 128-bit X.509 Version 3 certificate. The type of certificate is the same one that is used for common web servers. The signed certificate must be returned by the CA in base64 encoded format. It looks similar to this: -----BEGIN CERTIFICATE----- MIICjTCCAfagAwIBAgIDWnWvMA0GCSqGSIb3DQEBBAUAMIGHMQswCQYDVQQGEwJaQT EiMCAGA1UECBMZRk9SIFRFU1RJTkcgUFVSUE9TRVMgT05MWTEdMBsGA1UEChMUVGhh d3RlIENlcnRpZmljYXRpb24xFzAVBgNVBAsTDlRFU1QgVEVTVCBURVNUMRwwGgYDVQ QDExNUaGF3dGUgVGVzdCBDQSBSb290MB4XDTAyMDkyNzIzMzI0MVoXDTAyMTAxODIZ MzI0MVowaDELMAkGA1UEBhMCrVMxDTALBgNVBAgTBGJsYWgxDTALBgNVBAcTBGJsYW gxDTALBgNVBAoTBGJsYWgxDTALBgNVBAsTBGJsYWgxHTAbBgNVBAMTFHppZXIuc3Yu YXJjc2lnaHQuY29tMIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQCZRGnVfQwG1b +BgABd/p8UhsaNov5AjaagAoBmouJCwgW2vwN4JViC CSBkDpiqVF7K11Sx4ZVSXX4+VQ6k4gT5G0kDNvQeN05wWkzEMygMB+ZBnYqPA/XtWR ZtjxvH MoqS+JEqHruiMLITC6q0reUB/txby6+S9zNo/fUG1pkIcQIDAQABoyUwIzATBgNVHS UEDDAKBggrBgEFBQcDATAMBgNVHRMBAg8EAjAAMA0GCSqGSIb3DQEBBAUAA4GBAFY3 7E60+P4b3zTLnaG7EVM57GtkED6PwCIilB6ixjvNL4MNGRubPa8kyaZp5fEDoNUPQV QxnpABjzTalRfYgjNFJ6ltI6ZKjBO5kim9UBeCnKiNNzhIyDyFwbHXOPB/JaLIV+jG ugYNS7hf/ay0BXKlfueO07EgjhhB/mQFs2JB -----END CERTIFICATE----- Before proceeding, make sure the name of the issuer that signed your certificate exists as a Trusted CA in cacerts. (Use keytoolgui to check your cacerts.) Follow these steps to import the signed certificate: 1 If the returned file has the .CER or .CRT file extension, save it to the <ARCSIGHT_HOME>/config/jetty directory and skip to step 4. 2 Using any text editor, copy and paste the text string to a file. Include the line "----- BEGIN CERTIFICATE-----" and line "-----END CERTIFICATE-----", and make sure there are no extra spaces before or after the string. 3 Save it to a file named ca_reply.txt on the Manager in the <ARCSIGHT_HOME>/config/jetty directory. 4 On the Manager machine, run this command in <ARCSIGHT_HOME>/bin: ./arcsight keytoolgui 5 Click File->Open keystore and select the keystore (keystore.request or webkeystore.request) you saved in Step 7 in “Create a Key Pair for a CA-Signed Certificate” on page 49. Provide the password you used to save the keystore in that step. 6 Right-click the key pair you created at the beginning of the process and named mykey. 7 Select Import CA Reply from the menu. 8 Select the CA reply certificate file and click Import.
  • 52. 2 Configuration 52 Administrator’s Guide Confidential If the CA reply file contains a chain of certificates, the keytoolgui utility tries to match the reply’s root CA to an existing Trusted Certificate in your cacerts truststore. If this operation fails, the Certificate Details dialog appears for manual verification. Acknowledge the certificate by clicking OK and answering Yes to the subsequent challenge. Answer No if the certificate is not trustworthy for some reason. After the key pair you generated has been updated to reflect the content of the CA reply, the keystore named keystore.request contains both the private key and the signed certificate (in the alias mykey). 9 Select File > Save. The keystore is now ready for use by the Manager or ArcSight Web. 10 Make a backup of the existing keystore by renaming it: Rename <ARCSIGHT_HOME>/config/jetty/keystore to <ARCSIGHT_HOME>/config/jetty/keystore.old. If, for any reason, the new keystore does not work properly, you can revert back to the demo keystore by replacing keystore.old with the new keystore. For ArcSight Web, rename the file to webkeystore.old. 11 Copy <ARCSIGHT_HOME>/config/jetty/keystore.request to <ARCSIGHT_HOME>/config/jetty/keystore. For ArcSight Web, copy webkeystore.request to webkeystore. 12 For successful reconfiguration and Manager startup, enter the keystore passwords into the appropriate properties file. Enter the password into the webserver.properties file for ArcSight Web using the following command (all on one line): arcsight changepassword -f <ARCSIGHT_HOME>/config/webserver.properties -p server.privatekey.password Enter the password into the server.properties file for the Manager using the following command (all on one line): arcsight changepassword -f <ARCSIGHT_HOME>/config/server.properties -p server.privatekey.password After entering this command the system displays the previous password as asterisks and asks you to enter and then confirm your new password. These commands enter the password into the properties file in an encrypted format. 13 If your Manager clients trust the CA that signed your server certificate, go to “Restart the Manager” on page 53. Otherwise, perform these steps to update the client’s cacerts (truststore): a Obtain a root certificate from the CA that signed your server certificate and copy it to your client machine. b For one client, use the keytoolgui utility to import the certificate into the truststore (cacerts): Also perform these steps on the Manager to update the Manager’s cacerts so that Manager clients such as the archive utility can work.
  • 53. 2 Configuration Confidential Administrator’s Guide 53 i In <ARCSIGHT_HOME>/bin, run this command: ./arcsight keytoolgui ii Click File->Open keystore. iii Select the store named cacerts.

For the default password see “Cacerts password” on page 35. iv Click Tools->Import Trusted Certificate and select the certificate you copied in Step 10a of this procedure. v You see the following message. Click OK. vi Enter an alias for the Trusted Certificate you just imported and click OK. vii Right-click the alias ca in the truststore and choose Delete from the menu. viii Save the keystore. c Copy the <ARCSIGHT_HOME>/jre/lib/security/cacerts file from the client in the previous step to all other clients. 14 If your ArcSight Web browser clients trust the CA that signed your ArcSight Web certificate, go to Restart the Manager. Otherwise, perform these steps: a Obtain a root certificate from the CA that signed your ArcSight Web certificate. b Import the certificate into your web browser. See your browser’s documentation for details. Restart the Manager When you restart the Manager, clients it cannot communicate with it until their keystores are populated with the new certificate. 1 Restart the Manager. The Manager may fail to start if the password of the Key pair does not match the password of the keystore, which is encrypted in server.properties. If you do not remember the keystore password, run the Manager setup wizard and change the password of your existing keystore. 2 Restart all clients.
  • 54. 2 Configuration 54 Administrator’s Guide Confidential 3 To verify that the new certificate is in use: a From the command line navigate to <ARCSIGHT_HOME> and enter the command: arcsight tempca -i The output shows which CA issuer signed the SSL CA-signed certificate, certificate type, status of a validation of the certificate, and so on. b Point a web browser to https://<manager_hostname>:8443. to test it. Accommodating Additional Components Perform these extra steps to use CA-signed certificates with additional ArcSight Express components such as ArcSight Web, the ArcSight Console, or SmartConnectors.  Adding additional Managers You do not need to add the CA root certificate to the Truststore-cacerts file again. However, you must copy the cacerts file from the existing Manager to the new Manager.  Other ArcSight Components (Console, ArcSight Web, and SmartConnectors). When installing a new Console, you must copy the 'cacerts' file from the existing Console, which has been updated in the Phase 3, to the newly installed Console. This configuration procedure of Manager Ca-signed SSL certificate can be applied on the ArcSight Web server unless both components are installed on the same machine. For ArcSight Web, use the webserversetup utility after the certificate is updated to confirm the certificate is valid, as follows: a Login as an ArcSight Express user on the ArcSight Web server machine. b Execute the following command from <ARCSIGHT_HOME>/bin: ./arcsight webserversetup c Restart the ArcSight Web server. Removing a Demo Certificate You can remove the demo certificate by using the tempca script located in <ARCSIGHT_HOME>/bin. Issue the following command on all Manager and Console installations: arcsight tempca -rc For SmartConnectors, run the tempca script using the following command: arcsight agent tempca -rc Replacing an Expired Certificate When a certificate in your truststore/cacerts expires, you need to replace it with a new one. To replace the certificate: 1 Delete the expired certificate from the truststore/cacerts. To delete a certificate from the truststore or cacerts, start the keytoolgui and navigate to the certificate, right-click on the certificate, and select Delete. 2 Replace the certificate by importing the new certificate into truststore/cacerts as the case may be. Use the keytoolgui to import the new certificate into the truststore or

See “ArcSight WebUsing a Self-Signed Certificate” on page 44, or “Using a CA- Signed SSL Certificate” on page 48 section (depending on the type of certificate you are importing) for steps on how to import the certificate. Since the common name (CN) for the new certificate is identical to the CN in the old certificate, you are not permitted to have both the expired as well as the new certificate co- exist in the truststore, cacerts. Establishing SSL Client Authentication By default, clients (SmartConnectors, Consoles, and ArcSight Web) authenticate using user name and password. The clients can optionally use SSL authentication for clients. If SSL client authentication is enabled, you can optionally disable user name and password login, as described in the next section. When client-side authentication is used, the SSL clients contain a keystore and the SSL server contains a truststore. For information about managing certificates for SmartConnectors, see the Connector Management User’s Guide. Setting up SSL Client-Side Authentication on ArcSight Console To enable client-side authentication for ArcSight Console running in default mode, perform these steps in addition to the ones you perform for setting up server authentication: 1 On each Console, generate a key pair. For CA-signed certificate follow the steps in section “Create a Key Pair for a CA-Signed Certificate” on page 49.: a From the Console’s <ARCSIGHT_HOME>/bin directory start the keytoolgui by running the following command: ./arcsight keytoolgui b Open File->New keystore. This opens the New keystore Type dialog. c Select JKS and click OK. d Click Tools->Generate Key Pair and fill in the fields in the following dialog: Before you enable client-side authentication, make sure that you log in to the Console and create a new user or modify an existing user such that you set the user’s external_id to the one specified in the certificate created on the Console. The external id should be set to the users name set as the CN (Common Name) setting when creating the certificate. The Common Name field in the following screen should be the external ID of the user logging in to the Manager that this console connects to.

If you plan to install the Console, Manager, and Web on the same machine, make sure that this alias is unique. Also, do not use the machine name or IP address for the alias. ArcSight Web and Console cannot have identical CNs when installed on the same machine as the Manager. When you install ArcSight Web, set the CN of the ArcSight Web’s key pair you generate to the name or IP address of the machine on which you are installing it. Hence, if both Web and Console are on the same machine, and if you use the machine name or IP address for the CN for both the Web and the Console, then ArcSight Web gives you an error when configuring.

Migrating from one certificate type to another When you migrate from one certificate type to another on the Manager, you have to update all Consoles, SmartConnectors, and ArcSight Web installations. For information about managing certificates for SmartConnectors, see the Connector Management User’s Guide. Migrating from Demo to Self-Signed To migrate from a demo to self-signed certificate: 1 Follow the steps described in “ArcSight WebUsing a Self-Signed Certificate” on page 44. 2 Follow the instructions in “Verifying SSL Certificate Use” on page 70 to ensure that a self-signed certificate is in use. Make sure that this password is identical to the password that you set for /config/keystore.client when creating it.

Demo CA keystore C:arcsightConsolecurrentconfigkeystore.tempca Exiting... Using Certificates to Authenticate Users to ArcSight Instead of using a user name and password to authenticate a user to the Manager or ArcSight Web, you can configure these systems to use a digitally-signed user certificate. This section tells you how to do that. You can use Manager’s this capability in environments that make use of Public Key Infrastructure (PKI) for user authentication. The Manager and ArcSight Web accept login calls with empty passwords and use the Subject CN (Common Name) from the user’s certificate to identify the user. You must enable SSL client authentication as described in the previous section to use digitally-signed user certificates for user authentication. To configure the Manager or ArcSight Web to use user certificates, do the following: 1 On the Console, make sure that External ID field in the User Editor for every user is set to a value that matches the CN in their user certificate. 2 Restart the system you are configuring. 3 Restart the Consoles. When you start the Console, the user name and password fields are grayed out. Simply select the Manager to which you want to connect and click OK to log in. Using the Certificate Revocation List (CRL) ArcSight Express supports the use of CRL to revoke a CA-signed certificate that has been invalidated. The CA that issued the certificates also issues a CRL file containing a signed list of certificates that it had previously issued, and that it now considers invalid. The Manager checks the client certificates against the list of certificates listed in the CRL and denies access to clients whose certificates appear in the CRL. Before you use the CRL feature, make sure:  Your certificates are issued/signed by a valid Certificate Authority or an authority with an ability to revoke certificates.  The CA’s root certificate is present in the Manager’s <ARCSIGHT_HOME>/config/jetty/truststore directory. The Manager validates the authenticity of the client certificate using the root certificate of the signing CA.  You have a current CRL file provided by your CA. Before you enable client-side authentication, make sure that you log in to the Console and create a new user or modify an existing user such that you set the user’s external_id to the one specified in the certificate created on the Console. The external id should be set to the users name set as the CN (Common Name) setting when creating the certificate.
  • 72. 2 Configuration 72 Administrator’s Guide Confidential The CA updates the CRL file periodically as and when additional certificates get invalidated. To use the CRL feature: 1 Make sure you are logged out of the Console. 2 Copy the CA-provided CRL file into your Manager’s <ARCSIGHT_HOME>/config/jetty/crls directory. After adding the CRL file, it takes approximately a minute for the Manager to get updated. Reconfiguring the ArcSight Console after Installation You can reconfigure ArcSight Console at anytime by typing arcsight consolesetup within a command prompt window. Run the ArcSight Console Configuration Wizard by entering the following command in a command window in the <ARCSIGHT_HOME>/bin directory: ./arcsight consolesetup To run the ArcSight Console Setup program without the graphical user interface, type: ./arcsight consolesetup -i console The ArcSight Console Configuration Wizard appears. Reconfiguring Connectors Use the Connector Management module of the Management Console to reconfigure connectors that it manages. For information, see the Connector Management User’s Guide. For information about reconfiguring SmartConnectors on remote hosts and not managed by the Connector Management feature, refer to each SmartConnector’s SmartConnector Configuration Guide, and the SmartConnector User’s Guide. Reconfiguring ArcSight Manager To reconfigure Manager settings made during installation, run the Manager Configuration Wizard by typing the following command in a terminal box or command prompt window: ./arcsight managersetup The arcsight managersetup command opens the Manager Configuration Wizard, but you can also run the Manager Setup program silently by typing: ./arcsight managersetup -i console The Manager Configuration Wizard appears to help you re-configure the Manager. The managersetup wizard is covered in “Running the Manager Configuration Wizard” on page 91.
  • 73. 2 Configuration Confidential Administrator’s Guide 73 To change advanced configuration settings (port numbers, database settings, log location, and so on) after the initial installation, change the server.properties file. ArcSight’s default settings are listed in the server.defaults.properties file. You can override these default settings by adding the applicable lines from server.defaults.properties to the server.properties file. These files are located in <ARCSIGHT_HOME>/config. Changing ArcSight Manager Ports In order for every component of ArcSight to communicate, any ArcSight SmartConnectors and ArcSight Consoles must be aware of what IP address the Manager is running on. Also, the ArcSight SmartConnectors and ArcSight Consoles must use the same HTTP or HTTPS port numbers the Manager is currently using. The Manager uses a single port (by default, 8443) that any firewalls between the Manager, ArcSight Console, and any ArcSight SmartConnectors must allow communication through. Port 8443 is the default port used when initially installing ArcSight, however, you can change this default port number using the Manager Configuration Wizard. Changing ArcSight Web Session Timeouts The session timeout affects the web browser pages (i.e., Knowledge Base, reports, and so forth) that appear within ArcSight Web. After the session has elapsed, or timed out, you must log back into ArcSight Web to start a new session. You can change the Web default session timeout in this file in the Manager’s <ARCSIGHT_HOME>/config/jetty/server.xml file. The ArcSight Web default session timeout can be changed in this file in ArcSight Web’s <ARCSIGHT_HOME>/config/jetty/webserver.xml file. In the above .xml files you see the following lines: <session-config> <session-timeout>15</session-timeout> </session-config> The value specified, in this case 15, is the session timeout in minutes. Simply change this number to the session timeout desired and save the file. Managing Password Configuration The Manager supports a rich set of functionality for managing users passwords. This section describes various password configuration options. Generally, all the settings are made by editing the server.properties file. See “Managing and Changing Properties File Settings” on page 15. Some of these control character restrictions in passwords. Enforcing Good Password Selection There are a number of checks that the Manager performs when a user picks a new password in order to enforce good password selection practices.
  • 74. 2 Configuration 74 Administrator’s Guide Confidential Password Length The simplest one is a minimum and, optionally, a maximum length of the password. The following keys in server.properties affect this: auth.password.length.min=6 auth.password.length.max=20 By default, the minimum length for passwords is six characters and the maximum length is 20 characters and can contain numbers and/or letters. Configuring the above properties to a value of -1 sets the password length to unlimited characters. Restricting Passwords Containing User Name Another mechanism that enforces good password practices is controlled through the following server.properties key: auth.password.userid.allowed=false When this key is set to false (the default), a user cannot include their user name as part of the password. Password Character Sets For appliance users, the Manager comes installed using the UTF-8 character set. If you install the Manager, it allows you to set the character set encoding that the Manager uses. When you install the ArcSight Console, the operating system on that machine controls the character set the Console uses. Be sure the operating system uses the same character set as the Manager if:  A user password contains "non-English" characters (in the upper range of the character set: values above 127)  That user wants to log in with that ArcSight Console. This is not an issue if you log in from the web-based Management Console or ArcSight Web. For passwords that are in the ASCII range (values up to 127), the character set for the ArcSight Console does not matter. Requiring Mix of Characters in Passwords Good passwords consist not only of letters, but contain numbers and special characters as well. This makes them a lot harder to guess and, for the most part, prevents dictionary attacks. By default, the minimum length for passwords is six characters and the maximum length is 20 characters and can contain numbers and/or letters. The following properties control the distribution of characters allowed in new passwords: auth.password.letters.min=-1 auth.password.letters.max=-1
  • 75. 2 Configuration Confidential Administrator’s Guide 75 auth.password.numbers.min=-1 auth.password.numbers.max=-1 auth.password.whitespace.min=0 auth.password.whitespace.max=0 auth.password.others.min=-1 auth.password.others.max=-1 The *.min settings can be used to enforce that each new password contains a minimum number of characters of the specified type. The *.max settings can be used to limit the number of characters of the given type that new passwords can contain. Letters are all letters from A-Z, upper and lowercase, numbers are 0-9; “whitespace” includes spaces, etc.; “others” are all other characters, including special characters such as #$%@!. Additionally, the following server.properties key lets you restrict the number of consecutive same characters allowed. auth.password.maxconsecutive=3 For example, the default setting of 3 would allow "adam999", but not "adam9999" as a password. Furthermore, the following server.properties key enables you to specify the length of a substring that is allowed from the old password in the new password. auth.password.maxoldsubstring=-1 For example, if the value is set to 3 and the old password is “secret”, neither “secretive” nor “cretin” is allowed as a new password. Checking Passwords with Regular Expressions To accommodate more complex password format requirements, the Manager can also be set up to check all new passwords against a regular expression. The following server.properties keys can be used for this purpose: auth.password.regex.match= auth.password.regex.reject= The auth.password.regex.match property describes a regular expression that all passwords have to match. If a new password does not match this expression, the Manager rejects it. The auth.password.regex.reject property describes a regular expression that no password may match. If a new password matches this regular expression, it is rejected. For more information on creating an expression for this property, see http://www.regular- expressions.info/. The following are a few examples of regular expressions and a description of what they mean.  auth.password.regex.match= /^D.*D$/ Backslash ( ) characters in regular expressions must be duplicated (escaped)—instead of specifying , type .
  • 76. 2 Configuration 76 Administrator’s Guide Confidential Only passwords that do not start or end with a digit are accepted.  auth.password.regex.match= ^(?=.*[A-Z].*[A-Z])(?=.*[a-z].*[a- z])(?=.*[0-9].*[0-9])(?=.*[^a-zA-Z0-9].*[^a-zA-Z0-9]).{10,}$ Only passwords that contain at least 10 characters with the following breakdown are accepted:  At least two upper case letters  At least two lower case letters  At least two digits  At least two special characters (no digits or letters)  auth.password.regex.reject= ^(?=.*[A-Z].*[A-Z])(?=.*[a-z].*[a- z])(?=.*[0-9].*[0-9])(?=.*[^a-zA-Z0-9].*[^a-zA-Z0-9]).{12,}$ The passwords that contain 12 characters with the following breakdown are rejected:  At least two upper case letters  At least two lower case letters  At least two digits  At least two special characters (no digits or letters) Password Uniqueness In some environments, it is also desirable that no two users use the same password. To enable a check that ensures this, the following server.properties key can be used: auth.password.unique=false If set to true, the Manager checks all other passwords to make sure nobody is already using the same password. Setting Password Expiration The Manager can be set up to expire passwords after a certain number of days, forcing users to choose new passwords regularly. This option is controlled by the following key in server.properties: auth.password.age=60 By default, a password expires 60 days from the day it is set. When this setting is used, however, some problems arise for user accounts that are used for automated log in, such as the user accounts used for Manager Forwarding Connectors. These user accounts can be excluded from password expiration using the following key in server.properties: auth.password.age.exclude=username1,username2 This value is a comma-separated list of user names. The passwords of these users never expire. This feature may not be appropriate for some environments as it allows valid users of the system to guess other user’s passwords.
  • 77. 2 Configuration Confidential Administrator’s Guide 77 The Manager can also keep a history of a user’s passwords to make sure that passwords are not reused. The number of last passwords to keep is specified using the following key in server.properties: auth.password.different.min=1 By default, this key is set to check only the last password (value = 1). You can change this key to keep up to last 20 passwords. Restricting the Number of Failed Log Ins The Manager tracks the number of failed log in attempts to prevent brute force password guessing attacks. By default, a user's account is disabled after three failed log in attempts. This feature is controlled through the following key in server.properties: auth.failed.max=3 Change this to the desired number or to -1 if you do not wish user accounts to be disabled, regardless of the number of failed log in attempts. Once a user account has been disabled, the Manager can be configured to automatically re-enable it after a certain period of time. This reduces administrative overhead, while effectively preventing brute force attacks. This mechanism is controlled by the following key in server.properties: auth.auto.reenable.time=10 This value specifies the time, in minutes, after which user accounts are automatically re- enabled after they were disabled due to an excessive number of incorrect log ins. Set the property key to -1 to specify that user accounts can only be re-enabled manually. Re-Enabling User Accounts Under normal circumstances, user accounts that have been disabled—for example, as a result of too many consecutive failed log ins—can be re-enabled by any user with sufficient permission. Check the Login Enabled check box for a particular user in the User Inspect/Editor panel in the ArcSight Console. If the only remaining administrator user account is disabled, a command line tool can be run on the system where the Manager is installed to re-enable user accounts. First, ensure that the the Manager is running. Then, from the command line, run the following command: ./arcsight reenableuser username where username is the name of the user you want to re-enable. After this procedure, the user can log in again, using the unchanged password.
  • 78. 2 Configuration 78 Administrator’s Guide Confidential Advanced Configuration for Asset Auto-Creation Assets are automatically created for all components and, if applicable, for assets arriving from scan reports sent by vulnerability scanners via scanner SmartConnectors. This is done by the asset auto-creation feature. If the profile of events in your network causes asset auto creation feature to create assets in your network model inefficiently, you can modify the asset auto creation default settings in the user configuration file, server.properties. The server.properties file is located at $ARCSIGHT_HOME/config/server.properties. For more about working with properties files, see the topic “Managing and Changing Properties File Settings” Asset Auto-Creation from Scanners in Dynamic Zones The following properties relate to how assets are created from a vulnerability scan report for dynamic zones. Create Asset with either IP Address or Host Name By default, an asset is not created in a dynamic zone if there is no host name present. The property set by default is: scanner-event.dynamiczone.asset.nonidentifiable.create=false You can configure ArcSight Express to create the asset as long as it has either an IP address or a host name. In server.properties, change scanner- event.dynamiczone.asset.nonidentifiable.create from false to true. ArcSight Express discards conflicts between an IP address and host name (similar IP address, but different host name and/or MAC address). When this property is set to true, the following takes place: Creating an asset if no host name is present can result in an inaccurate asset model. Setting scanner-event.dynamiczone.asset.nonidentifiable.create to true means that assets are created if the asset has either an IP address or a host name. This could lead to disabled assets or duplicated assets being created. Change this configuration only if you are using a dynamic zone to host ostensibly static assets, such as long-lived DHCP addresses. Example Action taken if no conflicts Action taken if previous asset with similar information IP=1.1.1.1 hostname=myhost mac=0123456789AB Asset created Asset created, previous asset is deleted.
  • 79. 2 Configuration Confidential Administrator’s Guide 79 Preserve Previous Assets This setting applies when ArcSight Express creates assets from a vulnerability scan report for dynamic zones. By default, if a previous asset with similar information already exists in the asset model, ArcSight Express creates a new asset and deletes the old one. To preserve the previous asset rather than delete it when a scan finds a new asset with similar information, you can configure ArcSight Express to rename the previous asset. In server.properties, change scanner- event.dynamiczone.asset.ipconflict.preserve from false to true. When the system is configured with scanner- event.dynamiczone.asset.nonidentificable.create=false and scanner- ip=1.1.1.1 hostname=myhost mac=null Asset created Asset created, previous asset is deleted. ip=1.1.1.1 hostname=null mac=0123456789AB Asset created Asset created, previous asset is deleted. ip=1.1.1.1 hostname=null mac=null Asset created Asset created, previous asset is deleted. ip=null hostname=myhost mac=null Asset created Asset created, previous asset is deleted. ip=null hostname=null mac=0123456789AB Asset not created. Either host name or IP address is required. Asset not created. Either host name or IP address is required. ip=null hostname=myhost mac=0123456789AB Asset not created. Either host name or IP address is required. Asset not created. Either host name or IP address is required. Preserving previous assets results in a larger asset model. Setting event.dynamiczone.asset.ipconflict.preserve to true means that assets are continually added to the asset model and not removed. Use this option only if you know you must preserve all assets added to the asset model. Example Action taken if no conflicts Action taken if previous asset with similar information
  • 80. 2 Configuration 80 Administrator’s Guide Confidential event.dynamiczone.asset.ipconflict.preserve=true, it takes the following actions: Changing the Default Naming Scheme By default, the system names assets that come from scanners using the naming scheme outlined in the topic “Asset Names” in the ArcSight Console User’s Guide. You can reconfigure this naming scheme. For example, if you want the asset name for an asset in a static zone to appear this way in the ArcSight Console: myhost_1.1.1.1 Example Action taken if previous asset with similar information and preserve = true IP=1.1.1.1 hostname=myhost mac=0123456789AB Asset created, previous asset is renamed. ip=1.1.1.1 hostname=myhost mac=null Asset created, previous asset is renamed. ip=1.1.1.1 hostname=null mac=0123456789AB Asset created, previous asset is renamed. ip=1.1.1.1 hostname=null mac=null No action taken. Either host name or MAC address is required. ip=null hostname=myhost mac=null Asset created, previous asset is renamed. ip=null hostname=null mac=0123456789AB Asset created, previous asset is renamed. ip=null hostname='myhost' mac=0123456789AB Asset created, previous asset is renamed. Static Zone Dynamic Zone Property: scanner-event.auto- create.asset.name.template scanner-event.auto- create.dynamiczone.asset.name .template Value: $destinationAddress - $!destinationHostName $destinationHostName Example: 1.1.1.1 - myhost myhost
  • 81. 2 Configuration Confidential Administrator’s Guide 81 In this case, change the default $destinationAddress - $!destinationHostName to $!destinationHostName_$destinationAddress Compression and Turbo Modes Compressing SmartConnector Events ArcSight SmartConnectors can send event information to the Manager in a compressed format using HTTP compression. The compression technique used is standard GZip, providing compression ratio of 1:10 or higher, depending on the input data (in this case, the events the ArcSight SmartConnector is sending). Using compression lowers the overall network bandwidth used by ArcSight SmartConnectors dramatically, without impacting their overall performance. By default, all ArcSight SmartConnectors have compression enabled. To turn it off, add the following line to the <ARCSIGHT_HOME>/user/agent/agent.properties file: compression.enabled = false ArcSight SmartConnectors determine whether the Manager they are sending events to supports compression. Reducing Event Fields with Turbo Modes If your configuration, reporting, and analytic usage permits, you can accelerate the transfer of sensor information through SmartConnectors by choosing one of the "turbo" modes, which send fewer event fields from the connector. The default transfer mode is called Complete, which passes all the data arriving from the device, including any additional data (custom, or vendor-specific). ArcSight SmartConnectors can be configured to send more or less event data, on a per- SmartConnector basis, and the Manager can be set to read and maintain more or less event data, independent of the SmartConnector setting. Some events require more data than others. For example, operating system syslogs often capture a considerable amount of environmental data that may or may not be relevant to a particular security event. Firewalls, on the other hand, typically report only basic information. ArcSight Express defines the following Turbo Modes: When Turbo Mode is not specified (mode 3, Complete), all event data arriving at the SmartConnector, including additional data, is maintained. (Versions of ArcSight prior to 3.2 ran in Turbo Mode 3.) Turbo Mode 2, Faster, eliminates the additional custom or vendor- specific data, which is not required in many situations. Turbo Mode 1, Fastest, eliminates all but a core set of event attributes, in order to achieve the best throughput. Because the Turbo Modes 1 Fastest Recommended for firewalls 2 Faster Manager default
  • 82. 2 Configuration 82 Administrator’s Guide Confidential event data is smaller, it requires less storage space and provides the best performance. It is ideal for simpler devices such as firewalls. The Manager processes event data using its own Turbo Mode setting. If SmartConnectors report more event data than the Manager needs, the Manager ignores the extra fields. On the other hand, if the Manager is set to a higher Turbo Mode than a SmartConnector, the Manager maintains fields that are not filled by event data. Both situations are normal in real-world scenarios, because the Manager configuration reflects the requirements of a diverse set of SmartConnectors. Event data transfer modes are numbered (1 for Fastest, 2 for Faster, 3 for Complete), and possible Manager-SmartConnector configurations are therefore: 1-1 Manager and SmartConnector in Fastest mode 1-2 SmartConnector sending more sensor data than Manager needs 1-3 SmartConnector sending more sensor data than Manager needs 2-1 SmartConnector not sending all data that Manager is storing* 2-2 Manager and SmartConnector in Faster mode 2-3 Default: Manager does not process additional data sent by SmartConnector 3-1 Manager maintains Complete data, SmartConnector sends minimum* 3-2 Manager maintains additional data, but SmartConnector does not send it 3-3 Manager and SmartConnector in Complete mode *When the SmartConnector sends minimal data (Turbo Mode 1), the Manager can infer some additional data, creating a 2-1.5 or a 3-1.5 situation. 3 Sending Events as SNMP Traps ArcSight Express can send a sub-stream of all incoming events (that includes rule- generated events) via SNMP to a specified target. A filter is used to configure which events are sent. ArcSight Express’s correlation capabilities can be used to synthesize network management events that can then be routed to your enterprise network Management Console. Configuration of the SNMP trap sender The SNMP trap sender is configured using the Manager configuration file. The <ARCSIGHT_HOME>/config/server.default.properties file includes a template for the required configuration values. Copy those lines into your <ARCSIGHT_HOME>/config/server.properties file and make the changes there. After making changes to this file, you need to restart the Manager. Setting the Manager to send SNMP v3 traps is not FIPS compliant. This is because SNMP v3 uses the MD5 algorithm. However, SNMPv1 and v2 are compliant.
  • 83. 2 Configuration Confidential Administrator’s Guide 83 properties: The following provides a description of specific SNMP configuration parameters: snmp.trapsender.enabled=true Set this property to true in order to enable the SNMP trap sender. snmp.trapsender.uri= /All Filters/Arcsight System/SNMP Forwarding/SNMP Trap Sender The filter (specified by URI, all on one line) is used to decide whether or not an event is forwarded. There is no need to change the URI to another filter, as the "SNMP Trap Sender" filter can be changed through the ArcSight Console. Changes to the filter specified immediately affect the SNMP trap sender. By default, the "SNMP Trap Sender" filter logic is Matches Filter (Correlated Events)—that is, only rules-generated events are forwarded. snmp.destination.host= snmp.destination.port=162 The host name and the port of the SNMP listener that wants to receive the traps. snmp.read.community=public snmp.write.community=public The SNMP community strings needed for the traps to make it through to the receiver. The read community is reserved for future use, however, the write community must match the community of the receiving host. This depends on your deployment environment and your receiving device. Please consult your receiving device's documentation to find out which community string to use. snmp.version=1 snmp.fields= event.eventId, event.name, event.eventCategory, event.eventType, event.baseEventCount, event.arcsightCategory, event.arcsightSeverity, event.protocol, event.sourceAddress, event.targetAddress These event attributes should be included in the trap.

For example: The SNMP field types are converted as: Additional data values are accessible by name, for example: snmp.fields=event.eventName,additionaldata.myvalue This sends the Event Name field and the value of myvalue in the additional data list part of the SNMP trap. Only the String data type is supported for additional data, therefore all additional data values are sent as OCTET STRING. Asset Aging The age of an asset is defined as the number of days since it was last scanned or modified. So, for example, if an asset was last modified 29 hours ago, the age of the asset is taken as 1 day and the remaining time (5 hours, in our example) is ignored in the calculation of the asset’s age. You can use asset aging to reduce asset confidence level as the time since the last scan increases. Excluding Assets From Aging To exclude certain assets from aging, you can add those assets to a group and then set the property asset.aging.excluded.groups.uris in the server.properties file to the URI(s) of those groups. For example, to add the groups MyAssets and DontTouchThis (both under All Assets) add the following to the server.properties file: #Exclude MyAssets and DontTouchThis from aging asset.aging.excluded.groups.uris=/All Assets/MyAssets,/All Assets/DontTouchThis ArcSight Field SDK/SNMP trap sender identifier Event Name eventName Device Severity deviceSeverity Service service ArcSight SNMP STRING OCTET STRING INTEGER INTEGER32 Address IP ADDRESS LONG OCTET STRING BYTE INTEGER When setting the asset.aging.excluded.groups.uris property keep in mind that the assets in this group are not disabled, deleted or amortized.
  • 85. 2 Configuration Confidential Administrator’s Guide 85 Task to Disable Assets of a Certain Age By default, asset aging is disabled. There is a new scheduled task that disables any scanned asset that has reached the specified age. By default, once the assets aging feature is turned on this task runs every day half an hour after midnight (00:30:00). Add the following in the server.properties file to define asset aging: #----------------------------- # Asset aging #----------------------------- # Defines how many days can pass before a scanned asset is defined as old # after this time the asset will be disabled # Default value: disabled asset.aging.daysbeforedisable = -1 To Delete an Asset To delete the asset instead of disabling it, you have to set the property asset.aging.task.operation to delete in server.properties file: # Delete assets when they age asset.aging.task.operation = delete Amortize Model confidence with scanned asset age The IsScannedForOpenPorts and IsScannedForVulnerabilities sub-elements in the ModelConfidence element are factored by the age of an asset. They are extended to include an optional attribute, AmortizeScan. If AmortizeScan is not defined (or defined with value -1), the assets are not amortized. A "new" asset gets the full value while and "old" asset gets no points. You can edit the AmortizeScan value (number of days) in the Manager’s /config/server/ThreatLevelFormula.xml file: <ModelConfidence> <Sum MaxValue="10" Weight="10"> <!-- If target Asset is unknown, clamp modelConfidence to 0 - -> <HasValue FIELD="targetAssetId" Value="-10" Negated="Yes" /> <HasValue FIELD="targetAssetId" Value="4" Negated="NO" /> <!-- Give 4 points each for whether the target asset has been scanned for open ports and vulnerabilities --> <!-- This values can be amortized by the age of the asset --> <!-- that means that the value will reduce constantly over time as the asset age --> <!-- ie if you set the value to be 120 on the day the assets are created they receive the four points, by day 60 they'll receive 2 points and by day 120 they'll receive 0 points --> <IsScannedForOpenPorts Value="4" Negated="NO" AmortizeScan="-1" /> <IsScannedForVulnerabilities Value="4" Negated="NO" AmortizeScan="-1" /> </Sum> </ModelConfidence>

For complete instructions about how to install the connector, see the relevant SmartConnector installation and configuration guide, such as the SmartConnector Configuration Guide for Microsoft Active Directory Actor Model. Once installed, the connector polls the IDM and imports the user data into the Actor model. 2 Identify the authenticators in your environment. In preparation for configuring the authenticator mapping table, open the dashboard for automatically identifying the user authentication data stores running in your environment and their type: /All Dashboards/ArcSight Administration/ESM/Configuration Changes/Actors/Actor Administration This dashboard is populated by the following query viewer, which looks for events with a value in the Authenticator field: /All Query Viewers/ArcSight Administration/ESM/Configuration Changes/Actor/Actor Authenticators The example below shows the value of the Attributes field for an active directory system configured as Active Directory:<domain>.com. Use this exact value, including punctuation, spaces, and capitalization, to populate the account authenticators mapping table described in the next step. 3 Configure the Authenticators mapping table.

For details about starting and stopping the Manager, see “Basic Administration Tasks” in the Administrator’s Guide For details about working with the server.properties file, see “Managing and Changing Properties File Settings” in the Administrator’s Guide. Permissions Required to Use Actor-Related Data By default, Admin users have full read/write access to the actors feature and the other resources that actors depend on. The Admin can grant permissions for actors and the other resources upon which the actors feature depends to other users. To create actors, actor channels, and category models:  Read and write on /All Actors  Read and write on /All Session Lists/ArcSight System/Actor Data and /All Session Lists/ArcSight System/Actor Data Support  Read on /All Field Sets/ArcSight System/Actor Field Sets/Actor Base  Read on the filters used to define the event ACLS for that user group, for example, All Filters/ArcSight System/Core  Read and write on the group in which the new resource is being created To view actors and category models, and monitor actor channels:  Read on /All actors  Read on /All Session Lists/ArcSight System/Actor Data and /All Session Lists/ArcSight System/Actor Data Support  Read on /All Field Sets/ArcSight System/Actor Field Sets/Actor Base To use actor global variables provided in standard content rules, active channels, and reports that leverage actor data: Read access on the following resources and groups:  /All Fields/ArcSight System/Actor Variables (either directly, or inherited from /All Fields/ArcSight System)  /All Actors  /All Session Lists/ArcSight System  /All Active Lists/ArcSight System/Actor Data Support (for the authenticator active list)  /All Filters/ArcSight Foundation  The appropriate group that gives all the queries used by a query viewer that leverages actor data  The appropriate group that contains a query viewer that leverages actor data  The appropriate group(s) for the filters used by any queries and query viewers that leverage actor data
  • 89. 2 Configuration Confidential Administrator’s Guide 89 In addition to these permissions on the actor-related resources themselves, read permissions are needed for any resources (such as filters, user-created actor global variables, and so on) upon which these actor-related resources rely. For details about how to assign permissions to user groups, see “Granting or Removing Resource Permissions” on page 604. About Exporting Actors If you need to export your entire actor model to image another Manager, you can do it using the export_system_tables command-line utility using the -s parameter, the parameter used to specify export of session list data. The -s parameter captures the special session list infrastructure that is part of the Actor Resource Framework in addition to the actor resources themselves. For instructions about how to use the export_system_tables command-line utility, see the Administrator’s Guide. Best practice: Log out and log back in again for permission changes to take effect As a best practice whenever an admin changes another user’s permissions, the other user should log out and log back in again. This ensures that the new permissions are registered with the Manager, and the user can see the changes.

  • 97. 3 Running the Manager Configuration Wizard Confidential Administrator’s Guide 97 Authentication Details The authentication options enable you to select the type of authentication to use when logging into the Manager. By default, the system uses its own, built-in authentication, but you can specify third party, external authentication mechanisms, such as RADIUS Authentication, Microsoft Active Directory, LDAP, or a custom JAAS plug-in configuration. How external authentication works The Manager uses the external authentication mechanism for authentication only, and not for authorization or access control. That is, the external authenticator only validates the information that users enter when they connect to the Manager by doing these checks:  The password entered for a user name is valid.  If groups are applicable to the mechanism in use, the user name is present in the groups that are allowed to access ArcSight Manager. Users who pass these checks are authenticated. Once you select an external authentication mechanism, all user accounts, including the admin account, are authenticated through it. Guidelines for setting up external authentication Follow these guidelines when setting up an external authentication mechanism:  Users connecting to the Manager must exist on the Manager.  User accounts, including admin, must map to accounts on the external authenticator. If the accounts do not map literally, you must configure internal to external ID mappings in the Manager.  Users do not need to be configured in groups on the Manager even if they are configured in groups on the external authenticator.  If user groups are configured on the Manager, they do not need to map to the group structure configured on the external authenticator.  Information entered to set up external authentication is not case sensitive. • In order to use PKCS#11 authentication, you must select one of the SSL based authentication methods. • If you plan to use PKCS #11 token with ArcSight Web, make sure to select Password Based or SSL Client Based Authentication. • PKCS#11 authentication is not supported with Radius, LDAP and Active Directory authentication methods. See the appendix “Using the PKCS#11 Token‚” in the ArcSight Express Configuration Guide, for details on using a PKCS #11 token such as the Common Access Card (CAC).
  • 98. 3 Running the Manager Configuration Wizard 98 Administrator’s Guide Confidential  To restrict information users can access, set up Access Control Lists (ACLs) on the Manager. Password Based Authentication Password-based authentication requires users to enter their User ID and Password when logging in. You can select the built-in authentication or external authentication. Built-In Authentication This is the default authentication when you do not specify a third party external authentication method. If you selected this option, you are done. Setting up RADIUS Authentication To configure ArcSight Manager for RADIUS Authentication, choose RADIUS Authentication and supply the following parameter values: If you configure the Manager using Password Based and SSL Client Based Authentication or SSL Client Only Authentication, be aware that ArcSight Web does not support these modes. So: • If you plan to use ArcSight Web, you will need to configure your Manager to use Password Based Authentication or Password Based or SSL Client Based Authentication as your authentication method. • If you plan to use PKCS#11 authentication with ArcSight Web, be sure to select Password Based or SSL Client Based Authentication only. Parameter Description Authentication Protocol Which authentication protocol is configured on your RADIUS server: PAP, CHAP, MSCHAP, or MSCHAP2. RADIUS Server Host Host name of the RADIUS server. To specify multiple RADIUS servers for failover, enter comma-separated names of those servers in this field. For example, server1, server2, server3. If server1 is unavailable, server2 is contacted, and if server2 is also unavailable, server3 is contacted. RADIUS Server Type Type of RADIUS server: • RSA Authentication Manager • Generic RADIUS Server • Safeword PremierAccess RADIUS Server Port Specify the port on which the RADIUS server is running. The default is 1812. RADIUS Shared Secret Specify the RADIUS shared secret string used to verify the authenticity and integrity of the messages exchanged between the Manager and the RADIUS server.
  • 99. 3 Running the Manager Configuration Wizard Confidential Administrator’s Guide 99 Setting up Active Directory User Authentication To authenticate users using a Microsoft Active Directory authentication server, choose Microsoft Active Directory. Communication with the Active Directory server uses LDAP and optionally SSL. The next panel prompts you for this information. Specify any user who exists in AD to test the server connection. Specify the user name used to log in to the Manager and the External ID name to which it is mapped on the AD server. Configuring AD SSL If you are using SSL between the Manager and your authentication server, you must ensure that the server’s certificate is trusted in the Manager’s trust store <ARCSIGHT_HOME>/jre/lib/security/cacerts, whether the authentication server is using self-signed or CA certificates. For CA certificates, if the Certificate Authority (CA) that signed your server’s certificate is already listed in cacerts, you do not need to do anything. Otherwise, obtain a root certificate from the CA and import it in your Manager’s cacerts using the keytoolgui utility. For more information on importing certificates, see Understanding SSL Authentication in the Administrator’s Guide. Parameter Description Active Directory Server Host name of the Active Directory Server. Enable SSL Whether the Active Directory Server is using SSL. The default is True (SSL enabled on the AD server). No further SSL configuration is required for the AD server. Whether you selected SSL earlier for communications with the Console is irrelevant. Certificate type is set on the AD server side, not the manager. Active Directory Port Specify the port to use for the Active Directory Server. If the AD server is using SSL (Enable SSL=true), use port 636. If SSL is not enabled on the AD server, use port 389. Search Base Search base of the Active Directory domain; for example, DC=company, DC=com. User DN Distinguished Name (DN) of an existing, valid user with read access to the Active Directory. For example, CN=John Doe, CN=Users, DC=company, DC=com. The CN of the user is the "Full Name," not the user name. Password Domain password of the user specified earlier. Allowed User Groups Comma-separated list of Active Directory group names. Only users belonging to the groups listed here will be allowed to log in. You can enter group names with spaces.
  • 100. 3 Running the Manager Configuration Wizard 100 Administrator’s Guide Confidential Setting up LDAP Authentication The ArcSight Manager binds with an LDAP server using a simple bind. To authenticate users using an LDAP authentication server, choose Simple LDAP Bind and click Next. The next panel prompts you for this information. Specify any user who exists in LDAP to test the server connection. Enter a valid Distinguished Name (DN) of a user (and that user’s password) that exists on the LDAP server; for example, CN=John Doe, OU= Engineering, O=YourCompany. This information is used to establish a connection to the LDAP server to test the validity of the information you entered in the previous panel. Specify the user name used to log in to the Manager and the External ID name to which it is mapped on the LDAP server. Configuring LDAP SSL If you are using SSL between the Manager and your authentication server, you must ensure that the server’s certificate is trusted in the Manager’s trust store <ARCSIGHT_HOME>/jre/lib/security/cacerts, whether the authentication server is using self-signed or CA certificates. For CA certificates, if the Certificate Authority (CA) that signed your server’s certificate is already listed in cacerts, you do not need to do anything. Otherwise, obtain a root certificate from the CA and import it in your Manager’s cacerts using the keytoolgui utility. For more information on importing certificates, see Understanding SSL Authentication in the Administrator’s Guide. Using a Custom Authentication Scheme From the Manager Setup Wizard, you can choose the Custom JAAS Plug-in Configuration option if you want to use an authentication scheme that you have built. (Custom Authentication is not supported from the ArcSight Management Console.) You must specify the authentication configuration in a jaas.config file stored in the ArcSight Manager config directory. Parameter Description LDAP Server Host Specify the host name of the LDAP Server. Enable SSL Whether the LDAP Server is using SSL. The default is True (SSL enabled on the LDAP server). No further SSL configuration is required for the LDAP server. Whether you selected SSL earlier for communications with the Console is irrelevant. Certificate type is set on the LDAP server side, not the manager. LDAP Server Port Specify the port to use for the LDAP Server. If the LDAP server is using SSL (Enable SSL=true), use port 636. If SSL is not enabled on the LDAP server, use port 389. LDAP groups are not supported. Therefore, you cannot allow or restrict logging into the Manager based on LDAP groups. If you configure your Manager to use LDAP authentication, ensure that you create users on the Manager with their Distinguished Name (DN) information in the external ID field. For example, CN=John Doe, OU= Engineering, O=YourCompany.
  • 101. 3 Running the Manager Configuration Wizard Confidential Administrator’s Guide 101 Password Based and SSL Client Based Authentication Your authentication will be based both upon the username and password combination as well as the authentication of the client certificate by the Manager. Password Based or SSL Client Based Authentication You can either use the username/password combination or the authentication of the client certificate by the Manager (for example PKCS#11 token) to login if you select this option. SSL Client Only Authentication You will have to manually set up the authentication of the client certificate by the Manager. See the Administrator’s Guide for details on how to do this. You can either use a PKCS#11 Token or a client keystore to authenticate. Using PKCS#11 provider as your SSL Client Based authentication method within this option is not currently supported.

Separate multiple URIs (such as “/All Filters/Geographic/West Cost”) with a space, or repeat the –uri switch -urichildren <includeURIchildren> The URIs to export (there is no effect during import). All child resources of the specified resources are exported. A parent of a specified resource is only exported if the specified resource is dependent on it. -xrefids Exclude reference IDs. This option determines whether to include reference IDs during export. This is intended only to keep changes to a minimum between exports. Do not use this option without a complete understanding of its implications. -xtype <excludeTypes> The types to exclude during export. No effect during import. Exclude types must be valid type names, such as Group, Asset, or ActiveChannel. -xtyperef <excludeTypeRefs> The types to exclude during export (there is no effect during import). This is the same as -xtype, except it also excludes all references of the given type. These must include only valid type names such as Group, Asset, and ActiveChannel. -xuri <excludeURIs> The URIs to exclude during export. No effect during import. Resources for which all possible URIs are explicitly excluded are not exported. Resources which can still be reached by a URI that is not excluded are still exported. -xurichildren <excludeURIchildren> The URIs to exclude during export (there is no effect during import). These exclusions are such that all URIs for the children objects must be included in the set before the object will be excluded. In other words, they can still be exported if they can be reached through any path that is not excluded.

  • 132. A Administrative Commands 132 Administrator’s Guide Confidential restorearchives Description This command allows you to restore archive backups to a new system after a system failure. This tool assumes that you have already copied the archive backups to the location on the new system where your storage archive is located. That is, this restoration does not copy the archives into the system, you do that. It is restoring these archive entries to the new system’s database. After the command informs the system of these restored archives, they are listed on the Archives page, along with any archives that were already in the system and archives that are created later. The system does not differentiate between the archives loaded from a different installation and the ones created daily, locally. Notes: • Loading events from two installations to the local installation is not recommended. • You must stop the logger service before you run this command and restart it when you are done. • You must run this command as an ArcSight user. If the archive files’ owner is root or some other user, they cannot be reactivated. Applies to Database Syntax /opt/arcsight/logger/current/arcsight/logger/bin/arcsight restorearchives Parameters -r <root> The root directory that contains all archive backups you are restoring. All archives should be sub-directories of this directory. If unspecified, this command restores archives it finds in the default archive location, /opt/arcsight/logger/data/archives If you specify a different location the archive space used is not counted in the “Archive Jobs” administration page, and new archives still go to the default location. -i interactive Interactive mode. Confirmation is required before restoring each archive. Use this mode to select which archives to restore. -t test This option helps you validate the archives without actually loading them into the database. Use it to locate any archives that are corrupt or unreadable. -C clear Clears all events currently in the system and deletes any existing archive files that are currently listed in the database. It does this before the restoration operation, so you can use it to clear out the system. -h help Help for this command

  • 141. Confidential Administrator’s Guide 141 Appendix B Troubleshooting The following information may help solve problems that occur while operating the ArcSight system. In some cases, the solution can be found here or in specific ArcSight documentation, but Customer Support is available if you need it. If you intend to have Customer Support guide you through a diagnostic process, please prepare to provide specific symptoms and configuration information. If you intend to do the initial diagnostic steps yourself, proceed through the following checklist systematically, trying each applicable item and noting the results for reference. This appendix is divided into the following sections: General Report is empty or missing information. Check that the user running the report has inspect (read) permission for the data being reported. Running a large report crashes the Manager. A very large report (for example, a 500 MB PDF report) might require so much virtual machine (VM) memory that it can cause the Manager to crash and restart. To prevent this scenario, you can set up the Manager to expose a special report parameter for generating the report in a separate process. The separate process has its own VM and heap, so the report is more likely to generate successfully. Even if the memory allocated is still not enough, the report failure does not crash the Manager. This option must be set up on the Manager to expose it in the Console report parameters list. The steps are as follows: “General” on page 141 “Pattern Discovery Performance” on page 143 “Query and Trend Performance Tuning” on page 143 “SmartConnectors” on page 145 “ArcSight Console” on page 146 “Manager” on page 147 “ArcSight Web” on page 148 “SSL” on page 149
  • 142. B Troubleshooting 142 Administrator’s Guide Confidential 1 On the Manager in the server.properties file, set report.canarchivereportinseparateprocess=true. (This makes a new report parameter available on the Console.) 2 Save the server.properties file and restart the Manager. 3 On the ArcSight Console, open the report that you want to run in a separate process in the Report Editor, and click the Parameters tab. Set the parameter Generate Report In Separate Process to true. 4 Run the report. The report should run like a normal report, but it does not consume the resources of the Manager VM. Scheduled Rules Take too Long or Time Out If you have a system, perhaps one with a high EPS, in which the scheduled rules are not running quickly enough, you can enable them to run in parallel (multi-threading) to speed them up. Add the following property to the server.properties file: rules.replay.run.parallel=true You can also set the number of threads to use, as follows (the default if you do not use this property is four threads): rules.replay.numthreads=<number of threads to use> Some Asian language fonts appear mangled when generating reports in PDF This problem occurs because some Asian language fonts that are truetype fonts are not supported directly by versions of Adobe Reader earlier than version 8.0. In order to work around this, each truetype font must be mapped to an opentype font supported in Adobe Reader 8.0. ArcSight provides this mapping in the <ARCSIGHT_HOME>/i18n/server/reportpdf_config_<locale>.properties file. You have the option to change the default mapping of any truetype font to the opentype font by modifying the respective font mapping in this file. To work around the issue of mangled fonts, ArcSight recommends that you: 1 Install a localized Adobe Reader 8.0 depending on the language of your platform on your Manager machine. This version of the Adobe Reader installs the opentype fonts by default. 2 Edit the server.properties file as follows: a Set report.font.truetype.path property to point to the directory that contains the truetype and opentype font. The path is typically /usr/lib/font. The CIDFont directory is /usr/lib/font:<adobe_reader_dir>/Resource/CIDFont. b Set report.font.cmap.path property to point to Adobe Reader’s CMap directory. The CMap path is relative to the Adobe Reader installation -- <adobe_reader_dir>/Resource/CMap. Use this parameter only if you experience a Manager crash when running large reports such as the ones that contain tables with more than 500,000 rows and 4 or 5 columns per row.

Make sure that the POP3 or IMAP server is up and running, in order to process acknowledgements from notification recipients. Pager notification doesn’t happen. Check server.properties file to find which SNPP server is associated with the Manager. Make sure that the SNPP server is up and running. Pattern Discovery Performance Time spread calculations can take up a lot of CPU time, especially if Pattern Discovery has been running for a long time. If performance is degraded as a result of this feature, you can find out by checking the system.log for the start and end times of the Pattern Discovery process. If it is taking linger than expected, and if that is a problem for you, turn the Time Spread feature off. To turn it off, add the property patterns.timeSpreadCalculation=False to the Manager’s server.properties file. Query and Trend Performance Tuning To improve query execution in high-EPS systems, various queries used by the trends in the default ArcSight system have been optimized. The scheduler allocates two threads for processing system tasks. This alleviates performance issues caused by conflicts between system tasks and user level tasks within the scheduler. The following sections provide some troubleshooting tips. server.defaults.properties Entries for Trends  trends.query.timeout.seconds=7200
  • 144. B Troubleshooting 144 Administrator’s Guide Confidential This is the amount of time that a trend query is allowed to run, in seconds, before the SQL statement times out and the trend query fails. If absent or 0, no time-based timeout is applied.  trends.query.timeout.percent=50 This is the amount of time that a trend query is allowed to run, as a percentage of the query interval for interval trends, before the SQL statement times out and the trend query fails. If absent or 0, no percentage-based timeout is applied. As an example, with a 50 percent setting, a query covering a start/end time range of 1 hour times out after 30 minutes. A start/end time range covering 1 day would time out after 12 hours. If both timeouts are specified, the system uses the smaller of the two.  trends.query.failures.deactivation.threshold=3 If this many consecutive “accumulate” (not refresh) runs fail for any reason, the system automatically disables the trend. The check is always performed after any accumulate query run fails. Once the threshold is reached, any remaining queries to be executed by this task are skipped. If this setting is absent or 0, the checking mechanism is turned off. If a trend or query is stopped because of any of the above reasons, an audit event reflects this. Troubleshooting Checklist after Restarting the Manager  Use the Console Trend Editor to manually disable any trends that you do not need or that you notice have excessive query times. Disabling these trends helps reduce scheduler and database contention.  As trend data gathering tasks wake up, the trend attempts to fill in the gaps for missing intervals. Depending on the size of the gaps, this may take some time before the trends catch up.  A trend does not usually re-run any previously failed runs. If you want to re-run a particular time, you need to manually request it from the Trend Editor. Disable these Trends on High Throughput Systems If your system environment typically processes a very large number of events per second (EPS) (such as more than 1000 EPS or 100 million events per day), we recommend that you manually disable the following 9 trends, which are enabled by default: /All Trends/ArcSight Administration/ESM/User Access/ArcSight User Login Trends – Hourly /All Trends/ArcSight Foundation/Configuration Monitoring/Asset Configuration Change Tracking/Host Configuration Modifications /All Trends/ArcSight Foundation/Configuration Monitoring/Asset Restarts/Asset Startup and Shutdown Events - Daily Trend /All Trends/ArcSight Foundation/Configuration Monitoring/User Account Modifications/User Account Creation /All Trends/ArcSight Foundation/Configuration Monitoring/User Account Modifications/User Account Modifications /All Trends/ArcSight Foundation/Intrusion Monitoring/Operational Summaries/Reconnaissance/Port Scanning

You can use either of the following techniques, both using the ArcSight Console UI:  Using the Trend Data Viewer from within the Trends resource tree, you can see at most 2000 rows of data. (Select a trend in the resource tree, right-click, and choose Data Viewer.) Sort the trend timestamp column so that the timestamps show newest to oldest and observe when the newest value indicates it has caught up.  Using the Refresh... button in the Trend Editor, set the start time as far back as needed (days or weeks) to see any entries and click Refresh to see which runs show up as available to be refreshed. Only the most recent ones should show first. Note that you should not actually refresh any runs, but only use this technique to see what has been run. How long does it take a trend to catch up? This depends on how long the underlying query interval is, but a trend typically does up to 48 runs, as needed, when it wakes up. For a trend that queries an entire day and runs once a day, this would allow for more than a month’s worth of data to be queried. The data must be present on the system, however, or the query returns no results (but it does not fail). SmartConnectors My device is not one of the listed SmartConnectors. ArcSight offers an optional feature called the FlexConnector Development Kit which may enable you to create a custom SmartConnector for your device. ArcSight can create a custom SmartConnector. Contact Customer Support. My device is on the list of supported products, but it does not appear in the SmartConnector Configuration Wizard.

Console Cannot Connect to Manager If you start an ArcSight Console that could previously connect to the Manager with no trouble, but now it can’t, see if the error is similar to: “Couldn't connect to manager - improper authorization setup between client and manager.” If so, it’s likely that the manager has been reconfigured in such a way that it now has a new certificate. Especially if the Console asked you to accept a new certificate when you started it. To fix this, find and delete the certificate that the Console was using before, and then manually import another certificate from the Manager. Console reports out of memory. This can happen when you open many independent viewing channels. If you need to do this often, change the memory settings in the console.bat or console.sh file.

  • 153. Confidential Administrator’s Guide 153 Appendix C The Logfu Utility This appendix is divided into the following sections: Logfu is an ArcSight utility that analyzes log files. It is indispensable for troubleshooting problems that would otherwise require poring over text logs. Logfu generates an HTML report (logfu.html) and, especially in SmartConnector mode, includes a powerful graphic view of time-based log data. Logfu pinpoints the time of the problem and often the cause as well. Logfu has two windows: the interactive Chart and the Plot/Event window. “Running Logfu” on page 154 “Example” on page 156 “Troubleshooting” on page 156 “Menu” on page 158 “Typical Data Attributes” on page 158 “Intervals” on page 159
  • 154. C The Logfu Utility 154 Administrator’s Guide Confidential Running Logfu Logfu finds log files in the current directory. The –a or –m switches tell it which file names to look for. The –m switch tells it to look for all three Manager logs—server.std.log, server.log, and server.status.log—for example. To run Logfu, follow these steps: 1 Open a shell window in <ARCSIGHT_HOME>/logs/default. This refers to the logs directory under the ArcSight installation directory. Logfu requires an X Windows server. 2 Run logfu for the type of log to analyze: For Manager logs, run: ../bin/arcsight logfu –m For SmartConnector logs, run: ../bin/arcsight agent logfu –a 3 Right-click in the grid and select Show Plot/Event Window from the context menu. 4 Check at least one attribute (such as Events Processed) to be displayed. The initial display is always an empty grid. Loading very large log files can take a few minutes (a 100MB log might take 5 or 10 minutes). Once log files are scanned, the information gleaned from them is cached (in files named data.*), which speeds up loading the second time. If something about the log changes, however, you must manually delete the cache files to force logfu to reprocess the log. Right-click the grid and choose Show Plot/Event Window from the context menu. Select what to show on the grid from the Plot/Event Window that appears. The tree of possible things to display is divided into Plot—attributes that can be plotted over time, like events per second—and Event—one-time things, like exceptions, which are shown as vertical lines. Check as many things as you want to show. Because SmartConnectors can talk to multiple Managers and each can be configured to use multiple threads for events, the Plot hierarchy includes nodes for each SmartConnector and each Manager. Within the SmartConnector, threads are named E0, E1, and so on. Each SmartConnector has one heartbeat thread (H0) as well. Different types of SmartConnector
  • 155. C The Logfu Utility Confidential Administrator’s Guide 155 (firewall log SmartConnector, IDS SNMP SmartConnector, and so on) have different attributes to be plotted. The interactive Chart uses sliders to change the view. Hovering over a data point displays detailed information. There are two horizontal sliders—one at the top of the grid, one underneath. The slider at the top indicates the time scale. Drag it to the right to zoom in, or widen the distance between time intervals (vertical lines). The slider at the bottom changes the interval between lines—anywhere from 1 second at the far left to 1 day at the far right. The time shown in the grid is listed below the bottom slider: Showing YY/MM/DD HH:MM:SS – YY/MM/DD HH:MM:SS (Interval= X) Click anywhere in the grid area and drag a green rectangle to zoom in, changing both the vertical and horizontal scales at once. Hold the Ctrl key as you drag to pan the window in the vertical or horizontal direction, and hold both the Shift and Ctrl keys as you drag to constrain the pan to either vertical or horizontal movement. When you are panning, only sampled data is shown, but when you stop moving, the complete data fills in. (You can change this by unchecking Enable reduced data point rendering in Preferences.) Hover the mouse over a data point to see detailed information in a “tooltip” window, as shown in the figure, above.. For each attribute being plotted, a colored, vertical slider appears on the right of the grid. This slider adjusts the vertical (value) scale of the thing being plotted. By default, data points are connected by lines. When data is missing, these lines can be misleading. To turn off lines, uncheck Connect dots in Preferences. Once you have specified attributes of interest, scaled the values, centered and zoomed the display to show exactly the information of concern, select Save as JPG on the menu to create a snapshot of the grid display that you can print or e-mail. The size of the output image is the same as the grid window, so maximize the window to create a highly detailed snapshot, or reduce the window size to create a thumbnail.
  • 156. C The Logfu Utility 156 Administrator’s Guide Confidential Example Perhaps a particular SmartConnector starts by sending 10 events per second (EPS) to the Manager, but soon is sending 100, then 500, then 1000 EPS before dropping back down to 10. Logfu lets you plot the SmartConnector’s EPS over time—the result is something like a mountain peak. When you plot the Manager’s receipt of these events, you might see that it keeps up with the SmartConnector until 450 EPS or so. You notice that the Manager continues consuming 450 EPS even as the SmartConnector’s EPS falls off. This is because the Manager is consuming events that were automatically cached. By plotting the estimated cache size, you can see the whole story—the SmartConnector experienced a peak event volume and the cache stepped in to make sure that the Manager didn’t lose events, even when it couldn’t physically keep up with the SmartConnector. Use the vertical sliders on the right to give each attribute a different scale to keep the peak EPS from the SmartConnector from obscuring the plot of the Manager’s EPS. Troubleshooting Another real-world example involved a Check Point SmartConnector that was mysteriously down for almost seven days. Logfu plotted the event stream from the SmartConnector and it was clearly flat during the seven days, pinpointing the outage as well as the time that the event flow resumed. By overlaying Check Point Log Rotation events on the grid, it became clear that the event outage started with a Log Rotation and that event flow resumed coincident with a Log Rotation. Further investigation revealed what had happened—the first Check Point Log Rotation failed due to lack of disk space, which shut down event flow from the device. When the disk space problem had been resolved, the customer completed the Log Rotation and event flow resumed. If the Manager suddenly stops seeing events from a SmartConnector Logfu helps determine whether the SmartConnector is getting events from the device. Another common complaint is that not all events are getting through. Logfu has a plot attribute called ‘ZFilter’—zone filter—that indicates how many raw device events are being filtered by the SmartConnector. Events processed (the number of events sent by the device) minus

ArcSight_Meta_Tag is a string when using the #if statement for string comparison (for example, displayProduct) and is an integer for the #if statement for integer comparison (for example, severity). For a complete listing of ArcSight meta tags, see the Token Mappings topic in ArcSight FlexConnector Guide. Comparative_Operator is == for string comparison; =, >, and < for integer comparison. Compared_Value is a string or an integer. For string comparison, enclose the value in double quotes (“ ”).

The Informative.vm file lists all the non-empty fields of an event in the format fieldName : fieldValue. Understanding the Customization Process If you want to customize the template files to suit your needs, ArcSight recommends that you create new secondary templates containing fields that provide information you want to see in an e-mail for a specific condition. For example, if you want to see complete details for an event—Threat Details, Source Details, Target Details, and any other information—generated by all Snort devices in your network, create a secondary template file called Snort.vm in <ARCSIGHT_HOME>/config/notification, on your Manager, with the following lines: === Complete Event Details === Threat Details Event: $introspector.getDisplayValue($event,"name") Description: $introspector.getDisplayValue($event,"message") Severity: $introspector.getDisplayValue($event,"severity") ------------------------------------------------------------------ Source Details Source Address: $introspector.getDisplayValue($event,"attackerAddress") Source Host Name: $introspector.getDisplayValue($event,"attackerHostName") Source Port: $introspector.getDisplayValue($event,"sourcePort") Source User Name: $introspector.getDisplayValue($event,"sourceUserName") ------------------------------------------------------------------ Target Details

  • 167. Confidential Administrator’s Guide 167 Appendix E Configuration Changes Related to FIPS This appendix provides information about and instructions for configuring ArcSight Express to support Federal Information Processing Standard (FIPS) 140-2 and some other configuration changes you can make while in FIPS mode. FIPS is a standard published by the National Institute of Standards and Technology (NIST) and is used to accredit cryptographic modules in software components. A cryptographic module is either hardware or software or a combination that is used to implement cryptographic logic. The US Federal government requires that all IT products dealing with Sensitive, but Unclassified (SBU) information meet the FIPS standard.  To be compliant with FIPS 140-2, all components, including Connectors and Logger, if present, must be configured in FIPS mode. Connectors and Logger setup are covered in their documentation. For connectors, refer to each connector’s configuration guide and also see the Connector Management User’s Guide.  For information about supported platforms and specifics about FIPS mode architecture for all ArcSight Express products, contact ArcSight Customer Support.  TLS is based on SSL 3.0, for a better understanding of how SSL works. Read the section “Understanding SSL Authentication” on page 31. “Tools Used to Configure Components in FIPS” on page 168 “Types of Certificates Used in FIPS Mode” on page 168 “Some Often-Used SSL-Related Procedures” on page 172 “Setting up Server-Side Authentication” on page 177 “Setting up Client-Side Authentication” on page 177 “Changing the Password for NSS DB” on page 178 “Listing the Contents of the NSS DB” on page 179 “Veiwing the Contents of a Certificate” on page 179 “Setting the Expiration Date of a Certificate” on page 180 “Deleting a Certificate from NSS DB” on page 180 “Replacing an Expired Certificate” on page 180 “Using the Certificate Revocation List (CRL)” on page 181 “Changing a Default Mode Installation to FIPS 140-2” on page 184 “Configure Your Browser for FIPS” on page 188
  • 168. E Configuration Changes Related to FIPS 168 Administrator’s Guide Confidential Tools Used to Configure Components in FIPS Network Security Services (NSS) is a cross-platform cryptographic C library and a collection of security tools. ArcSight Express comes bundled with the following three basic NSS command line tools:  runcertutil - is a certificate and key management tool used to view and generate key pairs and certificate signing requests (CSR) and import and export public certificates from key pairs.  runmodutil - is the NSS module configuration tool. It is used to enable or disable the FIPS module and change key store passwords.  runpk12util - is an import and export tool for PKCS #12 format key pairs (.pfx files). See Appendix A‚ Administrative Commands‚ on page 105 for details on the above command line tools. You can also refer to the ‘NSS Security Tools’ page on the Mozilla website for more details on any of the above NSS tools (search for them as certutil, modutil, or pk12util). For online help on any command, enter the following command from a component’s bin directory: ./arcsight <command_name> -H References to ARCSIGHT_HOME <ARCSIGHT_HOME> in the paths represents  /opt/arcsight/manager for the Manager,  /opt/arcsight/console/current for the Console  /opt/arcsight/web for ArcSight Web. Types of Certificates Used in FIPS Mode When dealing with certificate based identification and encryption, components fall into one of two categories: servers and clients. Signed certificates enable these components to verify the validity of communications with the other components. You can use either a self- signed certificate or a CA-signed certificate when setting up SSL authentication on your ArcSight Express components. Enabling FIPS, SSL authentication, and certificate management for connectors is covered in the Connector Management User’s Guide. Using a Self-Signed Certificate When you use a self-signed certificate, the public part of the server’s key is used to identify and encrypt communications between the client and server. A self-signed certificate is automatically generated when doing a fresh installation of ArcSight Express. The runcertutil tool currently has a limitation that it cannot import the certificate when the NSS DB is set to FIPS mode. In order to work around this issue, you have to disable FIPS mode in the NSS DB, import the certificate, and then re-enable FIPS mode.
  • 169. E Configuration Changes Related to FIPS Confidential Administrator’s Guide 169 Using a Certificate Authority (CA) Signed Certificate In a configuration using a CA-signed certificate, the public part of the server’s key is sent to the client and the client identifies it using the Certificate Authority’s root certificate. The root certificate identifies the validity of the certificate by matching itself against the Issuer section of the public certificate. To obtain a CA signed certificate there are two options. 1 Buy or obtain a keypair from a Certificate Authority (CA). When putting in server data for your new server certificate, verify that the Subject Common Name (CN) matches the Fully qualified hostname (FQDN) or IP address of your server. 2 From your manager, Generate a Certificate Signing Request (CSR). Send the CSR to a Certificate Authority and retrieve the new keypair from the CA. After acquiring your new CA Signed Keypair, import it into the nssdb using the runpkcs12util utility. For all clients connecting to the server that uses the CA signed certificates, import the CA’s root certificate. It will be used to validate the certificate from the server. The instructions in this section for converting from the default self-signed certificates to a CA signed certificate assume that the Manager is already running in FIPS mode. For information on managing certificates for connectors, refer to the Connector Management User’s Guide. Steps Performed on the Manager Below are the steps to configure your ArcSight server application to use a CA signed certificate in fips 140-2 mode. 1 Stop the Manager. 2 Find out what the common name is 3 Delete any previously imported/generated Manager certificate or key pair. (Make sure you know the common name (CN) it uses before you delete it, because the new certificate needs to use the same CN.) ./arcsight runcertutil -D -n mykey -d /opt/arcsight/manager/config/jetty/nssdb 4 Generate a certificate signing request (CSR) by running the following from the Manager’s /bin directory: To create a PEM ASCII format CSR file: ./arcsight runcertutil -R -s "CN=<previous_CN>, O=<Name_of_organization>, L=<City_where_the_organization_is_located>, ST=<State_where_organization_is_located>, C=<Country>" -a -o <absolute_path_to_filename.csr> -d /opt/arcsight/manager/config/jetty/nssdb If you do not specify the absolute path to where the .csr file should go, the path specified for the output file will be relative to <ARCSIGHT_HOME> (/opt/arcsight/manager).
  • 170. E Configuration Changes Related to FIPS 170 Administrator’s Guide Confidential To create a DER binary file: ./arcsight runcertutil -R -s "CN=<hostname_or_IP>, O=<Name_of_organization>, L=<City_where_the_organization_is_located>, ST=<State_where_organization_is_located>, C=<Country>" -o <absolute_path_to_filename.csr> -d /opt/arcsight/manager/config/jetty/nssdb Enter the password for the NSS DB when prompted. The default is described in “NSS database password” on page 35. Enter random keyboard strokes when prompted to generate the random seed to generate your key. The CSR is generated in the location specified by the -o option. 5 Send the .csr file to your Certificate Authority. The Certificate Authority sends you a key pair consisting of a private key and a public certificate sighed by the CA. 6 After you receive the signed certificate from the CA, import it into the Manager’s NSS DB by running these commands from the Manager’s /bin directory: ./arcsight runcertutil -A -n mykey -t "C,C,C" -d /opt/arcsight/manager/config/jetty/nssdb -i <absolute_path_to_the_signed_certificate> 7 Start the Manager by running the following command as user arcsight: /sbin/service arcsight_services start manager Steps Performed on ArcSight Web ArcSight Web plays a dual role. On one hand, it acts as a client to the Manager to which it connects. On the other, it acts as a server to web browsers that connect to it. Therefore, ArcSight Web authenticates the Manager to which it connects and it also has to authenticate itself to web browsers. To authenticate the Manager, ArcSight Web’s NSS DB should contain the CA’s root certificate. At the same time, since the Web acts as a server to the web browsers that connect to it, you should have a key pair and a certificate containing ArcSight Web’s public key in the Web’s NSS DB. This allows ArcSight Web to authenticate iteself to the web browsers. You import the CA’s root certificate into ArcSight Web’s webnssdb. To obtain a CA-signed certificate for ArcSight Web, generate a key pair on ArcSight Web, generate a CSR on ArcSight Web, and send the CSR to the CA. Lastly, after you receive the signed certificate from the CA, import it into the webnssdb. 1 Stop ArcSight Web, if it is running. Delete any previously imported/generated Manager certificate or key pair. (Make sure you know the common name (CN) it uses before you delete it, because the new certificate needs to use the same CN.) ./arcsight runcertutil -D -n mykey -d /opt/arcsight/web/config/jetty/webnssdb
  • 171. E Configuration Changes Related to FIPS Confidential Administrator’s Guide 171 2 Import the CA’s root certificateinto the webnssdb by running the following from ArcSight Web’s bin directory. (For the -t option, make sure the you specify “CT,C,C” exactly as shown.) ./arcsight runcertutil -A -n <certificate_alias> -t "CT,C,C" -d /opt/arcsight/web/config/jetty/webnssdb -i <absolute_path_to_the_CA’s_root_certificate> This is required in order for ArcSight Web to be able to authenticate the Manager. 3 Generate a key pair on ArcSight Web by running: 4 Generate a CSR in the webnssdb which you have to send to the CA to obtain a CA- signed certificate for ArcSight Web: ./arcsight runcertutil -R -s "CN=<previous_CN>, O=<company_name>, L=<Location_of_the_company>, ST=<State_where_company_is_located>, C=<country>" -a -o <absolute_path_to_the_filename.csr> -d /opt/arcsight/web/config/jetty/webnssdb This generates a CSR file that is placed in the location you had specified in the -o option in the command. 5 Send the .csr file to your Certificate Authority. The Certificate Authority sends you a key pair consisting of a private key and a public certificate sighed by the CA. 6 After you receive ArcSight Web’s signed certificate from the CA, import it into ArcSight Web’s webnssdb by running: ./arcsight runcertutil -A -n mykey -t "C,C,C" -d /opt/arcsight/web/config/jetty/webnssdb -i <absolute_path_to_ArcSight_Web_certificate> The web browsers that connect to the webserver use ArcSight Web’s certificate to authenticate the webserver. 7 Start ArcSight Web by running the following from its /bin directory as user arcsight: /sbin/service arcsight_services start arcsight_web Steps Performed on the ArcSight Console You are required to import the CA root certificate into the Console’s nssdb.client. This allows the Console to trust the Manager. • Make sure the CN is either the IP address of the machine on which ArcSight Web resides or its fully qualified domain name used in the URL when you access ArcSight Web using a browser. • If you do not specify the absolute path to where the .csr file should go, the path specified for theoutput file will be relative to <ARCSIGHT_HOME> (/opt/arcsight/web). Make sure that you have copied the CA root certificate to the machine on which install the ArcSight Console.
  • 172. E Configuration Changes Related to FIPS 172 Administrator’s Guide Confidential 1 Import the root certificate from the Certificate Authority (CA) used to sign the managers certificate by running: arcsight runcertutil -A -n <provide_an_alias_for_the_cert> -t “CT,C,C” -d <ARCSIGHT_HOME>currentconfignssdb.client -i <path_to_the_CA’s_root_certificate> For the -t option, be sure to use CT,C,C permission flags only and in the order shown above. 2 Start the Console. You should see a message saying that the Console is starting in FIPS mode. Some Often-Used SSL-Related Procedures Here are some of the commonly used SSL-related procedures that are intended to serve as a reference when installing or setting up ArcSight Express components in FIPS mode. Generating a Key Pair in a Component’s NSS DB This section explains how to generate a key pair in a component’s NSS DB. A component that has to authenticate itself is required to have a key pair on it. For example, during server-side authentication, since the server needs to authenticate itself to a client, the server should have a key pair in its NSS DB and send its certificate which contains the server’s public key to the client requesting it. The same is true for client-side authentication where a key pair has to exist on the client. For self-signed certificate, the certificate gets generated when generating a key pair. On the Manager 1 Run the following command from the Manager’s <ARCSIGHT_HOME>/bin directory to generate a key pair: ./arcsight runcertutil -S -s “CN=<hostname>” -v <number_of_months_the_certificate_should_be_valid> -n mykey -k rsa -x -t “C,C,C” -m 1234 -d /opt/arcsight/manager/config/jetty/nssdb When you import or generate a key pair in a component’s NSS DB, if there is a existing key pair/certificate that has the same CN as the one you create, the runcertutil utility uses the existing alias for the newly created key pair and ignore the alias you supplied in the runcertutil command line. • Make sure to use mykey as the alias name for the key pair as shown in the example. • The -m serial number should be unique within nssdb • The hostname is the short name or fully qualified domain name depending upon how your Manager name was set up when you installed the Manager. • Using -v to set the validity period of your certificate is optional. Using -v is optional. If you choose to use it, see “Setting the Expiration Date of a Certificate” on page 180 for details. To dee the validity period of an existing certificate, see “Viewing Certificate Details” on page 40.
  • 173. E Configuration Changes Related to FIPS Confidential Administrator’s Guide 173 In the above command, the hostname is the name of the machine on which your Manager is installed and -v is the validity period of the certificate. For example, if your hostname is myhost.arcsight.com, you would run: ./arcsight runcertutil -S -s “CN=myhost.arcsight.com” -v 6 -n mykey -k rsa -x -t “C,C,C” -m 1234 -d /opt/arcsight/manager/config/jetty/nssdb This generates a key pair and certificate with the alias mykey which is valid for 6 months from the current date and time in the Manager’s nssdb. 2 Enter the password for NSS DB when prompted. The default is described in “NSS database password” on page 35. 3 Enter random keyboard strokes when prompted, to generate the random seed used to generate your key. On ArcSight Web To create a key pair on the Web server: 1 Run the following command from ArcSight Web’s /bin directory: ./arcsight runcertutil -S -s “CN=<hostname>” -v <number_of_months_the_certificate_should_be_valid> -n mykey -k rsa -x -t “C,C,C” -m 2345 -d <ARCSIGHT_HOME>/config/jetty/webnssdb  The -m serial number (2345) must be unique within webnssdb. That is, it must be different than the one for the Manager’s key pair.  hostname is the name of the machine on which ArcSight Web is installed.  Using -v is optional. If you choose to use it, see “Setting the Expiration Date of a Certificate” on page 180 for details. 2 Enter the password for webnssdb. The default is described in “NSS database password” on page 35. 3 Enter random keyboard strokes when prompted, to generate the random seed used to generate your key. Verifying Whether the Key pair Has Been Successfully Created To verify whether the key pair has been successfully created in the nssdb, run the following from the component’s <ARCSIGHT_HOME>/bin directory: ./arcsight runcertutil -L -d <path_to_the_component’s_NSS DB> Viewing the Contents of the Manager Certificate If you would like to check the contents of the certificate, you run this from the component’s /bin directory: ./arcsight runcertutil -L -d <path_to_the_component’s_NSS DB> - n mykey When you import or generate a key pair into NSS DB, if there is a existing key pair/certificate with the same CN as the one you create, the runcertutil utility uses the existing alias for the newly created key pair and ignores the alias you supplied in the runcertutil command line.
  • 174. E Configuration Changes Related to FIPS 174 Administrator’s Guide Confidential Exporting Certificates This section explains how to export a certificate from a component’s NSS DB. During an SSL handshake, for server side authentication, you need to have the server’s certificate in the NSS DB of both the server and the client. Export the server’s certificate from the server’s NSS DB in order to import it into the client that wishes to connect to the server. Likewise, for client side authentication, you need to have the client’s certificate in the NSS DB of both the client and the server. Export the client’s certificate from the client’s NSS DB in order to import it into the server to which the client connects. For information on managing certificates for connectors, refer to the Connector Management User’s Guide. Exporting a Certificate From the Manager Run the following command from the Manager’s <ARCSIGHT_HOME>/bin directory: ./arcsight runcertutil -L -n <alias_for_exported_certificate> -r -d /opt/arcsight/manager/config/jetty/nssdb -o <absolute_path_to_where_you_want_certificate_exported> For example: ./arcsight runcertutil -L -n mykey -r -d /opt/arcsight/manager/config/jetty/nssdb -o /home/arcsight/arcsight/Manager/ManagerCert.cer This exports the Manager’s certificate into a file called ManagerCert.cer and places it in your /home/arcsight/arcsight/Manager directory. The alias for this file is mykey. Exporting a Certificate From the Console To export the Console’s certificate run the following from the Console’s bin directory: arcsight runcertutil -L -n <alias_for_exported_certificate> -r -d <ARCSIGHT_HOME>currentconfignssdb.client -o <absolute_path_to_where_you_want_certificate_exported> Exporting a Certificate From the Web To export the Web’s certificate, run the following from the Web’s /bin directory: If you do not specify the absolute path for the .cer file, it is placed in the Manager’s <ARCSIGHT_HOME> directory. If you do not specify the absolute path for the .cer file, it gets placed in the Console’s <ARCSIGHT_HOME> folder.

For server side authentication, the server’s certificate needs to be imported into the client’s NSS DB. For client side authentication, the client’s certificate needs to be imported into the server’s NSS DB. Use runcertutil to import a certificate into the NSS DB. The runcertutil tool currently has a limitation that it cannot import the certificate when the component is running in FIPS mode. In order to work around this issue, you have to disable FIPS mode on the component first, then import the certificate, and lastly re-enable FIPS mode. For information on managing certificates for connectors, refer to the Connector Management User’s Guide. On the Manager If you use a CA-signed certificate, import the Manager’s CA-signed certificate into the Manager’s nssdb. In addition, if you set up client side authentication, import the client’s certificate into the Manager’s nssdb. Import a certificate into the Manager’s nssdb by running: ./arcsight runcertutil -A -n <provide_an_alias_for_the_certificate> -t “CT,C,C“ -d /opt/arcsight/manager/config/jetty/nssdb -i <absolute_path_to_the_certificate_file> For the -t option, be sure to use CT,C,C permissions flags only and in the same order that it is shown above. If you are importing the Console’s certificate to set up client-side authentication, make sure that you do NOT use the alias mykey for the Console’s certificate when importing it into the Manager’s nssdb because the nssdb already has the Manager’s certificate with the alias mykey in it. All aliases in the nssdb should be unique. On the Console Import the Manager’s certificate into the Console that connects to the Manager. To import a certificate into the Console’s nssdb.client: arcsight runcertutil -A -n <provide_an_alias_for_the_cert> -t “CT,C,C” -d <ARCSIGHT_HOME>confignssdb.client -i <absolute_path_to_certificate_file> For the -t option, be sure to use CT,C,C permissions flags only and in the same order that it is shown above. On ArcSight Web To import the Manager’s certificate into ArcSight Web’s webnssdb: If you do not specify the absolute path for the .cer file, it gets placed in the Web’s optarcsightweb folder.
  • 176. E Configuration Changes Related to FIPS 176 Administrator’s Guide Confidential ./arcsight runcertutil -A -n <provide_an_alias_for_the_cert> -t “CT,C,C” -d /opt/arcsight/web/config/jetty/webnssdb -i <absolute_path_to_the_certificate_file> For the -t option, be sure to use CT,C,C permissions flags only and in the same order that it is shown above. Importing an Existing Key Pair into the NSS DB If you already have an existing key pair, you can use it instead of generating a new key pair on a component. This procedure instructs you how to import an existing key pair into a component’s NSS DB. 1 Export the key pair using a tool, such as keytoolgui, and be sure to export the key pair with the name you gave it. An alias is required in order to import the key pair into NSS DB. 2 Import the .pfx file into NSS DB using the runpk12util tool. Make sure that the alias of the key pair being imported does not match the alias of a pre-existing key pair in the component’s NSS DB. If the key pair being imported has an alias that matches a pre-existing key pair, the key pair fails to import citing an error: PKCS12 decode validate bags failed: The user pressed cancel. Run the following command from the component’s /bin directory On the Manager: ./arcsight runpk12util -i <absolute_path_to_mykey.pfx> -d /opt/arcsight/manager/config/jetty/nssdb On the Web: ./arcsight runpk12util -i <absolute_path_to_mykey.pfx> -d /opt/arcsight/web/config/jetty/webnssdb On the Console: arcsight runpk12util -i <absolute_path_to_mykey.pfx> -d <ARCSIGHT_HOME>currentconfignssdb.client 3 Run the following from the component’s <ARCSIGHT_HOME>/bin directory to verify that the key pair has been imported correctly. Note that the alias of the key pair that you just imported in the NSS DB is the same as the alias of that key pair in the .pfx file, in our example, mykey. On Manager: ./arcsight runcertutil -L -d /opt/arcsight/manager/config/jetty/nssdb On Web: ./arcsight runcertutil -L -d /opt/arcsight/web/config/jetty/webnssdb You should see the alias of the imported key pair in the output.
  • 177. E Configuration Changes Related to FIPS Confidential Administrator’s Guide 177 Setting up Server-Side Authentication When you install a component in FIPS mode, you set it up for server-side authentication. Setting up client-side authentication is optional. Setting up Client-Side Authentication SSL 3.0 supports client-side authentication. TLS is based on SSL 3.0. ArcSight Express uses TLS and supports client-side authentication. The client side authentication takes place after the initial handshake (after the Manager has authenticated itself to the Console). The Manager then requests the Console for its (Console’s) certificate. The Console in turn sends its certificate to the Manager. The Manager has to be configured to accept the Console’s certificate. In other words, the Console’s certificate must exist in the Manager's nssdb prior to the Manager authenticating the Console. With this high level overview in mind, here are the steps you need to perform to set up client-side authentication. If you plan to use self-signed certificate for the Console: 1 Stop the Console if it is running. 2 Generate a key pair in the Console’s nssdb.client. Follow the steps in “Generating a Key Pair in a Component’s NSS DB” on page 172 (“On the Console” subsection). This automatically generates a self-signed certificate on the Console’s NSS DB. Alternatively, you can use an existing key pair which you have to import into the Console’s NSS DB. See “Importing an Existing Key Pair into the NSS DB” on page 176 for details. 3 Export the Console’s certificate. See the section “Exporting Certificates” on page 174 (“From the Console” subsection) for detailed instructions. 4 Stop the Manager if it is running. 5 Import the Console’s certificate into the Manager’s nssdb.

Changing the Password for NSS DB ArcSight Express ships with a default password for the NSS DB (see “NSS database password” on page 35). ArcSight recommends that you change the password on each component before moving to a production environment. To do so: 1 Disable the FIPS mode in NSS DB by running the following from the component’s /bin directory: ./arcsight runmodutil -fips false -dbdir <absolute_path_to_the_component’s_NSS DB> 2 Run the following to list the NSS DB’s token name: ./arcsight runmodutil -list -dbdir <absolute_path_to_the_component’s_NSS DB> 3 Change the token’s password by running the following from the component’s /bin directory: ./arcsight runmodutil -changepw “<name_of_token>” -dbdir <absolute_path_to_the_component’s_NSS DB> 4 Enter the old password and a new password and confirm it when prompted. 5 Re-enable FIPS mode on the NSS DB: ./arcsight runmodutil -fips true -dbdir <absolute_path_to_the_component’s_NSS DB> 6 Open the properties file: On the Manager: Located in: /opt/arcsight/manager/config/server.properties. Change server.privatekey.password.encrypted=<encrypted_password> to server.privatekey.password=<new_unencrypted_password> On the Console: If you do not specify the absolute path to where you want the .csr file to be placed, the .csr file gets placed in the Console’s <ARCSIGHT_HOME>.

This is required in order to obfuscate the password that you had entered in plain text. Listing the Contents of the NSS DB After you import a certificate or generate a key pair in a component’s NSS DB, you can verify that the certificate import was successful or the key pair has been successfully generated. You can do this by listing the contents of the NSS DB. To view the contents of a component’s NSS DB, run the following command from the component’s /bin directory: ./arcsight runcertutil -L -d <absolute-path-to-the_component’s_NSS DB> You should see the alias of the certificate you just imported or the alias for the key pair you generated.

  • 180. E Configuration Changes Related to FIPS 180 Administrator’s Guide Confidential Setting the Expiration Date of a Certificate To set the expiry date of the certificate, you have to do so when generating the key pair. Once you have generated the key pair, you cannot change the expiration date on the certificate and the certificate expires in three months by default. ./arcsight runcertutil -S -s “CN=<hostname>” -v <number_of_months_the_certificate_should_be_valid> -n mykey -k rsa -x -t “C,C,C” -m 1234 -d <component’s_NSS DB_path> You specify the validity of the certificate with the -v <number_of_months> option. The value that you provide with -v calculates the number of months that the certificate is valid starting from the current time. You can use the -w <offset_months> along with -v to set the beginning time for the validity. The -w <offset_months> if used, calculates the start time of the certificate validity and the offset is calcualted from the current system time. If you do not use the -w option, the current time is used as the start time for the certificate validity. See the subsection, “runcertutil” in Appendix A‚ Administrative Commands‚ on page 105 for details on the -v and -w options. Deleting a Certificate from NSS DB To delete a certificate from a component’s NSS DB: 1 Stop the component if it is running. 2 Run the following command from the component’s /bin directory: ./arcsight runcertutil -D -n <certificate-alias> -d <absolute- path-to-the_component’s_NSS DB> Replacing an Expired Certificate When an existing certificate/nssdb expires on a server (Manager or Web), you need to replace it with a new one. You can see when a certificate will expire by opening it. To replace the certificate: 1 Stop all services by running the following command (as user arcsight): /sbin/service arcsight_services stop all 2 Delete the expired certificate from the server’s NSS DB. See “Deleting a Certificate from NSS DB” on page 180 for details. Since the common name (CN) for the new certificate is identical to the CN in the old certificate, you are not permitted to have both the expired as well as the new certificate co-exist in the NSS DB. 3 In case of CA-signed certificate, replace the certificate by importing the new certificate into the server’s NSS DB. In case of self-signed certificate, you have to generate a key pair on the server. See “Generating a Key Pair in a Component’s NSS DB” on page 172 for details on how to do this. Generating the key pair automatically generates the certificate. 4 On every client that connects to the server, make sure to delete the old expired server certificate from the client’s NSS DB and import the server’s newly generated certificate. For example, if your Manager’s certificate has expired, you have to
  • 181. E Configuration Changes Related to FIPS Confidential Administrator’s Guide 181 a Delete the expired certificate from the Manager’s nssdb. See “Deleting a Certificate from NSS DB” on page 180 b Generate a new key pair, which automatically generates a new self-signed certificate. See “Generating a Key Pair in a Component’s NSS DB” on page 172 c Export the newly generated certificate from the Manager. See “Exporting Certificates” on page 174 d Delete the expired Manager’s certificate from the Console’s and Web’s NSS DB. e Generate a new keypair in the Web’s nssdb which effectively generates a new certificate on the Web. See “Generating a Key Pair in a Component’s NSS DB” on page 172 f Import the Manager’s new certificate into the Console’s and Web’s NSS DB. See “Importing a Certificate into the NSS DB” on page 175 Using the Certificate Revocation List (CRL) Starting in v4.0 SP2, ArcSight Express supports the use of CRL to revoke a CA-signed certificate which has been invalidated. The CA that issued the certificates also issues a CRL file which contains a signed list of certificates which it had previously issued that it now considers invalid. The Manager checks the client certificates against the list of certificates listed in the CRL and denies access to clients whose certificates appear in the CRL. Before you use the CRL feature, make sure:  Your certificates are issued/signed by a valid Certificate Authority or an authority with an ability to revoke certificates.  The CA’s certificate is present in the Manager’s /opt/arcsight/manager/config/jetty/nssdb directory In the case of client-side authentication, the Manager validates the authenticity of the client certificate using the certificate of the signing CA.  You have a current CRL file provided by your CA. The CA updates the CRL file periodically as and when additional certificates get invalidated. To use the CRL feature: 1 Make sure you are logged out of the Console. 2 Copy the CA-provided CRL file into your Manager’s /opt/arcsight/manager/config/jetty/crls directory. After adding the CRL file, it takes about a minute for the Manager to get updated. Configuration Required to Support Suite B Suite B is a set of cryptographic algorithms put forth by the National Security Agency (NSA) as part of the national cryptographic technology. While FIPS 140-2 supports sensitive but unclassified information, FIPS with Suite B supports both unclassified information and most classified up to top secret information. In addition to AES, Suite B includes cryptographic algorithms for hashing, digital signatures, and key exchange. When configured to use Suite B mode, ArcSight Express supports Suite B Transitional profile. There are 2 level of security defined in Suite B mode:

E Configuration Changes Related to FIPS 182 Administrator’s Guide Confidential  TLS_ECDHE_ECDSA_WITH_AES_128_CBC_SHA Suite B 128-bit security level, providing protection from classified up to secret information  TLS_ECDHE_ECDSA_WITH_AES_256_CBC_SHA Suite B 192-bit security level, providing protection from classified up to top secret information Generating a Keypair on the Manager The key pair you generate is used to generate the self-signed certificate. The self-signed certifcate automatically gets generated when you generate the key pair. The Manager’s key pair and certificate get generated and stored in its nssdb. The Manager’s public key is embedded in its certificate, thereby linking the Manager’s identity to its public key. a Run the following command from the Manager’s <ARCSIGHT_HOME>/bin directory to generate a key pair. This automatically generates the Manager’s certificate. If you want to set the expiry date of the certificate, you have to do so when generating the key pair. Once you have generated the key pair, you cannot change the expiry date on the certificate. ./arcsight runcertutil -S -s “CN=<hostname>” -v <number_of_months_the_certificate_should_be_valid> -n mykey -k ec -q secp521r1 -x -t “C,C,C” -m 1234 -d /opt/arcsight/manager/config/jetty/nssdb For example, if your hostname is host.arcsight.com, you would run: ./arcsight runcertutil -S -s “CN=host.arcsight.com” -v 6 -n mykey -k ec -q secp521r1 -x -t “C,C,C” -m 1234 -d /opt/arcsight/manager/config/jetty/nssdb When you import or generate a key pair into nssdb, if there is a existing key pair/certificate that has the same Common Name (CN) as the one you create, the runcertutil utility uses the alias of the existing key pair for the newly created key pair and ignores the alias you supplied in the runcertutil command line. • Make sure to use “mykey” (without quotes) as the alias name for the key pair as shown in the example. • The -m serial number should be unique within nssdb • The hostname is the short name or fully qualified domain name depending upon how your Manager name was set up when you installed the Manager. • Using -v to set the validity period of your certificate is optional. If you do not use this option, the certificate is valid for 3 months by default. If you choose to use it, see “Setting the Expiration Date of a Certificate” on page 180 section in the Administrator’s Guide for details. • The -q defines the PQG value with which an ECDSA certificate is generated.

Enter random keyboard strokes when prompted to generate the random seed used to generate your key. This generates a key pair and certificate with the alias mykey which is valid for 6 months from the current date and time in the Manager’s nssdb. b To check whether the key pair has been successfully created in the nssdb, run the following from the Manager’s <ARCSIGHT_HOME>/bin directory: ./arcsight runcertutil -L -d <ARCSIGHT_HOME>/config/jetty/nssdb Exporting the Manager’s Certificate To export the Manager’s certificate, run the following command from the Manager’s /opt/arcsight/manager/bin directory: ./arcsight runcertutil -L -n <certificate_alias> -r -d /opt/arcsight/manager/config/jetty/nssdb -o <absolute_path_to _managercertificatename.cert> For example, to export the certificate as a file named ManagerCert.cer to C:arcsightManager directory, run: ./arcsight runcertutil -L -n mykey -r -d /opt/arcsight/manager/config/jetty/nssdb -o /opt/arcsight/manager/ManagerCert.cer This generates the ManagerCert.cer file, the Manager’s certificate, in the /opt/arcsight/manager directory. Importing a Certificate into the Manager Import a certificate into the Manager: ./arcsight runcertutil -A -n <certificate_name> -t “CT,C,C” -d /opt/arcsight/manager/config/jetty/nssdb -i <absolute_path_to_the_root_certificate> For the -t option, be sure to use CT,C,C permissions flags only and in the same order that it is shown above. The -o specifies the absolute path to where you want to place the exported Manager’s certificate. If you do not specify the absolute path the file is exported to your /opt/arcsight/manager directory by default.
