REST API Overview
Using the EnterpriseView REST API you can import and export asset data in the following ways:
l Import assessments on assets from any external security system or tool, eliminating the need to
manually assess assets in EnterpriseView.
l Export assessments on assets to any external security system or tool.
Note: You can import or export assessment information only for assets of type IP; this
assessment information is aggregate to top-level assets as in manual assessments
l Exporting asset aggregate scores to any external security system or tool, including:
n The aggregate risk score of the asset
n The aggregate compliance score of the asset
n The aggregate control maturity score of the asset
n The aggregate asset vulnerability score of the asset
n The aggregate ESM threat score of the asset
Prerequisites:
Make sure that the following entities and parameters are identical in both EnterpriseView and the
Security Automation tool:
l Assets of type IP
l Policy names
l Control paragraph numbers
The following HTTP request methods for importing and exporting asset data are available:
l GET: Reads one of the following resources from the EnterpriseView server:
n Asset ID
n P5 control maturity scores for multiple (1-5) factors
n Compliance score of an asset with a control
n Note on a control that is applied to an asset
n The aggregate scores of an asset
l PUT: Updates/creates the following resources on the EnterpriseView server:

n P5 control maturity score for a single factor
n P5 control maturity scores for multiple (1-5) factors
n Compliance score of an asset with a control
l POST: Inserts notes on a control that is applied to an asset on the EnterpriseView server.
The first step of a client application is authenticating the user, as described in "Authentication" on
page 21. After a client is authenticated, it can work with EnterpriseView resources.

Asset Reconciliation
Description
Reconciliation is the process of identifying and matching entities from different data repositories, for
example, in HP Server Automation (SA) and EnterpriseView. This process is designed to assure
unique identification of assets in EnterpriseView.
The asset ID is passed as a parameter in all of the other methods. Therefore, retrieving the asset
ID is always the first action.
Parameters
The asset ID can be retrieved with one or more of the following parameters:
l IP Address
l MAC Address
l Host Name
URL
http://{host}:{port}/redcat/rest/reconcile/
asset?ipAddress={ipAddress}
asset?macAddress={macAddress}
asset?hostname={hostname}
Or any combination of parameters. For example:

asset?hostname={hostname}&macAddress=
{macAddress}&ipAddress={ipAddress}
Note: The IP Address, MAC Address and Host Name of an asset can change. In this case,
using these parameters may return a different asset ID. If your connector has a unique key for
this asset that is made up of the Connector Asset ID and the Connector Name, then we
recommend using these parameters to make sure that the same asset is always returned.
URL
asset?connectorName={connectorName}&connectorAssetId=
{connectorAssetId}&hostname={hostname}
{connectorAssetId}&ipAddress={ipAddress}
{connectorAssetId}&macAddress={macAddress}
Or any combination of parameters. For example:
asset?connectorName=MyConnector&connectorAssetId=17&ipAddress=
192.168.0.1&hostname=assetHost&macAddress=assetMAC
Remark
EnterpriseView can return only one asset ID. If more than one asset is found with this method, then
404 error code is returned. None of the parameters (IP address, MAC address, host name) are
mandatory in EnterpriseView. Using your knowledge of EnterpriseView, construct your queries to
match a unique asset.
GET
Action Returns one asset ID.
Request Body None
Returns <?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<asset>
<id>{asset ID}</id>
</asset>
Example GET http://127.0.0.1:8080/redcat/rest/reconcile/asset?
