THE GROWING NEED TO PROTECT SENSITIVE DATA IN THE CLOUD
Many organizations now consider data to be one of their most valuable
organizational assets. However, if that data is not well protected, it can
quickly become a liability. Practically every day we hear stories about high-
profile data breaches, as well as attacks on individual systems and
databases (see sidebar). Growing privacy concerns have increased the
regulations that dictate how organizations treat user data, including the
European Union’s General Data Protection Regulation (GDPR), the United
States’ Health Insurance Portability and Accountability Act (HIPAA), the
new California Consumer Protection Act (CCPA), and other governing
bodies. It’s an expensive problem, and the associated fines for non-
compliance have made it even more so. For example, Marriott was forced
to pay more than £99 million in fines; and British Airways faces £183 million
in fines for recent GDPR breaches.
Attackers may be full-time employees of a nation-state, members of an
organized crime syndicate, or just curiosity seekers, but they all have one
thing in common: a propensity to leverage gaps in your security strategy.
While some of these attacks are designed to wreak havoc on business
operations, others are motivated by a more explicit goal: to steal your data.
And since this data typically resides in a database, the latter becomes the
prime target for hackers.
In addition to this constant barrage of external threats, companies also face
threats from internal users — sometimes intentional, and other times
through inadvertent errors, omissions, and oversights involving security
software configurations and the associated data.
The distributed nature of today’s work teams only exacerbates the problem.
Organizations must commonly manage many types of users in many
different geographies — including internal DevTest teams and external
partner organizations — all of which require differing levels of access to
corporate databases.
Data Breaches in the News
• In 2019, Capital One reported
one of the top 10 largest data
breaches ever. The breach was
discovered after details of
the hack were posted on the
code sharing website, GitHub.
• In April 2019, vpnMentor
discovered an unsecured
database hosted on Microsoft
Azure that contained personal
information on nearly 80 million
U.S. households.
• In February 2018, FedEx
realized that they had
inadvertently exposed the
personal information from
119,000 of their customers in a
database on an unsecured
Amazon Web Services (AWS)
cloud storage server. The
discovery was made by
Kromtech Security and it is
estimated this information went
unsecured for four years before
being discovered.
The Cost of Compliance
• GDPR fines can be as high as
four percent of annual revenue
• HIPAA fines can be US$1.5
million per violation
• CCPA fines will be as high as
$700 per individual — plus
litigation costs

To mitigate both intentional and unintentional breaches, enterprises need
to identify sensitive data, protect it with appropriate controls, and routinely
audit usage of that data in database management systems. Some business
leaders are concerned about moving databases to the cloud because of
these security issues — compounded by a shortage of in-house expertise
protecting sensitive data.
This paper describes Oracle Data Safe, an integrated and comprehensive
cloud service that ensures data security for cloud databases. Data Safe
helps secure your databases via security and user risk assessments, user
activity auditing, sensitive data discovery, and data masking. With this well-
integrated and easy-to-use solution, cloud database customers of all sizes
and in all verticals can meet their database security requirements very
easily.
DEMOCRATIZING SECURITY WITH ORACLE DATA SAFE
As data and applications move to the cloud, the responsibility for securing an organization’s assets
becomes progressively more complex. While cloud service providers are responsible for securing their
global infrastructure and protecting client databases from access by their own personnel, each cloud
customer must implement its own measures to secure its users and data.
For example, in an Infrastructure as a service (IaaS) environment, a cloud provider may secure cloud
infrastructure, operating systems, and network services, but not the applications and users that access
the data. Organizations are responsible for deciding what sensitive data goes into the database and
which users can access it. This isn’t something that a cloud vendor can decide, as it is specific to each
company’s industry, operations, customer base, and business goals.
To properly protect organizational data, it is necessary to first know how it’s configured, who is using it,
and what types of sensitive data each database contains. It also means keeping track of who needs to

access production data (versus sample, masked, or aggregate data), and putting a process in place for
removing that data when it is no longer needed.
Oracle Data Safe is an important part of this multifaceted security strategy. It provides an integrated set
of capabilities that will help you secure your users and configurations as well as meet data security
compliance requirements. Oracle Data Safe is your single point of control for managing data security in
the cloud.
Oracle Data Safe provides a unified security control center for cloud databases
CONTROLLING ACCESS TO SENSITIVE DATA IN FIVE EASY STEPS
Enterprise databases frequently include large quantities of personal information, making them attractive
targets for hackers who want to steal data and disrupt business practices. To mount a strong defense
you need to know precisely where your sensitive data is located and who is accessing that data. In
addition, knowing what risks are associated with your users and having the ability to audit activities are
critical to a good security posture. Oracle Data Safe makes it easy to systematically complete these
tasks with five inter-related components:
» Security Assessment
» User Assessment
» Activity Auditing
» Data Discovery
» Data Masking
Oracle Data Safe puts these five components together into a unified, user-friendly environment, so you
don’t need multiple tools — and highly skilled database security experts — to protect your data. This
popular service is available today for databases on Oracle Cloud Infrastructure.

A unified security control center for Oracle Cloud Databases
Step 1: Security Assessment
A security assessment helps you determine if there are gaps in your configuration strategy, and offers
guidance on how to remediate those gaps. The Security Assessment feature enables you to identify
security vulnerabilities and to verify that encryption, auditing, and access controls have been
implemented.
Oracle Cloud Database allows flexibility in how customers configure users, privileges, and security
controls to meet different requirements. For example, the user and security controls implemented for a
production system containing sensitive customer data might differ from those for a development system
with synthetic test data. The Security Assessment feature of Oracle Data Safe enables you to examine
security configuration parameters so you can implement the correct level of security and controls for
each application. This might include, for example, identifying when default passwords are being used or
when users have more privileges than they should. The findings and recommendations support both the
European Union General Data Protection Regulation (EU GDPR) and the Center for Internet Security
(CIS) benchmark.

Use the Security Assessment to examine security parameters and implement application controls
Step 2: User Assessment
Oracle Data Safe includes user assessment and monitoring capabilities that help you pinpoint risks,
especially associated with privileged users and accounts. You can now identify the database users who
pose the highest risk if their accounts were to be compromised or if they were to go rogue and become
bad actors. These accounts might require a higher level of monitoring or a possible reduction in
privileges within the context of their roles. User Assessment reports help you quickly identify dormant
accounts for locking or removal. Links from the User Assessment reports to the Activity Auditing
function show the audited activities performed by the users.

The User Assessment feature allows administrators to identify and evaluate privileged accounts
Step 3: Activity Auditing
With Data Safe Activity Auditing, you can monitor user activities on Oracle Cloud databases, collect and
retain audit records per industry and regulatory compliance requirements, and trigger alerts for unusual
activity. You can audit sensitive data changes, administrator and user activities, and other activities
recommended by the Center for Internet Security. You can set up alerts when a database parameter or
audit policy changes, a failed login by an admin occurs, user entitlements change, and when a user is
created or deleted. The Oracle Database includes a number of pre-defined polices and any of these
can be enabled through Data Safe with just a few clicks.
The Data Safe dashboard (shown on page 6) lets you quickly spot trends in activity, including alerts.
From the dashboard, you can also check on the status of the audit trails (audit trails tell Data Safe
where in the database to look for audit data) and see the overall auditing activity.
There are several activity auditing
reports provided, such as,
summary of events collected and
alerts, all audited activities, audit
policy changes, admin activity,
login activity, database query
operations, DDLs, DMLs, and
user and entitlement changes.
You can view the generated alerts
and filter and search for them.
Both alerts and audit data reports
can be customized and saved or
downloaded in PDF or XLS
format.

Admin Activity Reports
Setting up Activity Auditing in Data Safe is a simple 3-step process: 1) Select the targets you want to
audit 2) Provision audit policies specifying what audit information will be collected 3) Create audit trails
that tell Data Safe from where to collect audit information.

Event Details
Once this is done, Data Safe automatically retrieves audit data and stores it in the secure Data Safe
repository (separate from the database being monitored so it can’t be deleted or altered). You can set
up alerts on key events based on the predefined set of alerts available in Data Safe Activity Auditing.
Interactive reports allow you to look at audit data, filter it as needed, and create scheduled reports to
meet your security and compliance needs.
Step 4: Data Discovery
With multiple development teams and data distributed over multiple databases, it’s not always easy to
know where your sensitive data is. In order to protect your data, you need to understand what kind of
sensitive data you have, how much of it you have, and where it resides. Sensitive Data Discovery helps
Many organizations don’t really
know how secure their databases
are, how much sensitive data they
have, or where their sensitive
data is located.

you decide what to protect. It identifies and classifies 125+ sensitive types of data, such as PII, IT data,
financial data, employment data, and health data.
The Data Discovery pre-defined sensitive data types
You can select the sensitive data categories that you want to discover, such as personally identifiable
information or healthcare information. You can also easily define custom categories of new sensitive
data types that match your organization’s requirements.
Data Discovery reports on sensitive data
Step 5: Data Masking
Being able to share production data with test and development teams helps you to improve the quality
of your applications through real-world data. But copies of production systems carry all the sensitive
data (and the risk associated with that data) into environments which are not as well protected as your
production environments. Besides, the sensitive data such as credit card numbers are not really
needed. This is where Data Masking comes in. Data Masking replaces sensitive data in an application
database with fictitious but realistic values. You can then share those data sets with application

developers, application testers, and partners. This gives them a realistic data set for testing and
developing applications — without exposing sensitive data. As Data Masking is integrated with Data
Discovery, a compatible masking format is automatically suggested for any discovered sensitive data.
Data Safe lets you discover and mask sensitive data with just a few clicks.
Data masking reduces risk by obfuscating sensitive data.
The Data Masking feature of Oracle Data Safe uses the information discovered during the sensitive
Data Discovery process to create data masking policies to protect, for example, social security
numbers, credit card numbers, financial data, salary information, and personal health information. Data
masking replaces real data with disguised, yet realistic, data within development, testing, and partner
databases, and includes more than 50 predefined masking formats.
A HYPOTHETICAL SCENARIO INVOLVING SENSITIVE PATIENT DATA
Consider a database used by a healthcare organization to store the results of diagnostic test results.
With Oracle Data Safe, the security team can assess the database configuration (including password
policies, parameter settings, and patch levels) to ensure the database is configured according to best
practices. They can then quickly assess database users to identify which users have privileges that
make them most at risk for inappropriate access to data, and configure audit policies to monitor their
database activity. They can use sensitive Data Discovery to scan the database to identify which
schemas, tables and columns contain sensitive patient data. When copies of the database are made for
test and development or partners, they can now automatically replace sensitive data with realistic
looking trials data. And they can do all of this from a single console in just a few minutes.
BRINGING IT ALL TOGETHER
Data Safe runs on the Oracle Cloud Infrastructure and is a key part of an over-arching security
strategy that runs from the infrastructure itself to our latest self-securing Oracle Autonomous
Database. In the following sections, we’ll explore this relationship in more detail.
Data Masking maintains relational
integrity with support for shuffle
masking, conditional masking,
compound masking, SQL
expression masking, user-defined
masking, and other masking
formats.

The relationship of Oracle Data Safe to Autonomous Database and Oracle Cloud Infrastructure
BETTER DATABASE SECURITY WITH ORACLE AUTONOMOUS DATABASE
Oracle Data Safe extends the self-securing capabilities of the Oracle Autonomous Database to protect
data while it's in use and to continuously monitor the users who access that data. We have a multi-
pronged strategy to protect your data and free DBAs to focus on high-value tasks such as
understanding their data and instituting proper protections and controls.
Oracle Autonomous Database is a revolutionary cloud service that simplifies database administration
and tuning tasks, including automatically maintaining security configurations. For example, by
automatically applying patches in a rolling fashion across the nodes of a cluster, Oracle Autonomous
Database secures itself without application downtime. Security patches are applied every quarter or as
needed to the firmware, operating system, clusterware, and database — with no downtime.
Patching is just part of the picture. The database also protects itself with always-on encryption.
Encryption protects your data in situations where a breach allows a hacker to access the data blocks
directly. This practice ensures that even if database files with sensitive data are copied, they are
useless to cybercriminals. Oracle Autonomous Database encrypts customer data while it is in motion, at
rest, and in backups.
By liberating database administrators from the daily repetitive management chores such as database
tuning, patching, and backups, Oracle Autonomous Database allows DBAs to focus on high-value tasks
such as application management, and keeping sensitive data secure.
SECURITY AT MULTIPLE LAYERS WITH ORACLE CLOUD INFRASTRUCTURE
Oracle secures today’s complex database environments with an intelligent, cloud-based platform that
prevents, detects, and rapidly responds to security threats.
For example, Oracle Cloud Infrastructure is based on seven core pillars to ensure customers have the
isolation, data protection, control, and visibility required for a robust cloud infrastructure. Oracle’s
machine learning algorithms add intelligence to security operations center (SOC) activities and a cloud
Oracle handles a number of
crucial security concerns for its
cloud customers automatically,
including the following:
• Network security and monitoring
• OS and platform security
• Database patches and
upgrades
• Administrative separation of
duties
• Data encryption by default

access security broker (CASB) automatically detects threats to cloud applications. At the edge, Oracle
security services include distributed denial of service (DDoS) Protection and a web application firewall
to defend against internet-based threats. Finally, Oracle assumes the responsibility of protecting your
infrastructure with a highly trained, 24/7 network operations center (NOC) staff. Oracle’s security
technology, process, and operations reduce the risk, cost, and complexity of moving to the cloud. With
multiple layers of defense, Oracle combats cyber threats with core-to-edge cloud services that secure
your data and thwart cyber threats.
CONCLUSION
As databases move to the cloud, enterprises need to proactively monitor how their data is managed
and accessed, and by whom it is used. While cloud providers secure your infrastructure and the
platform services, it’s up to you to secure your applications, users, and data. The Oracle Data Safe
cloud service integrates all of your security needs including assessing your configuration and users,
auditing user activity for compliance, and identifying sensitive data for masking — all through a single
dashboard that allows you to quickly and easily secure your data assets.
