Manage Database Security with Oracle Data Safe

About Oracle Data Safe

Your corporate policy requires that you monitor your databases and retain audit records. Your developers are asking for copies of production data for that new application, and you're wondering what kinds of sensitive information it will contain. Meanwhile, you need to make sure that recent maintenance activities haven't left critical security configuration gaps on your production databases and that staff changes haven't left dormant user accounts on the databases. Oracle Data Safe assists you with these tasks and is included with your Exadata Database Service*.

Oracle Data Safe is a unified control center, that helps you to manage the day-to-day security and compliance requirements of Oracle Databases no matter if they are running in the Oracle Cloud Infrastructure, at Cloud@Customer, on-premises or in any other cloud.

Data Safe supports you to evaluate security controls, assess user security, monitor user activity, and address data security compliance requirements for your database by evaluating the sensitivity of your data as well as masking sensitive data for non-production databases.

Data Safe provides the following features:

  • Security Assessment: Configuration errors and configuration drift are significant contributors to data breaches. Use security assessment to evaluate your database's configuration and compare it to Oracle and industry best practices. Security assessment reports on areas of risk and notifies you when configurations change.
  • User Assessment: Many breaches start with a compromised user account. User Assessment helps you spot the riskiest database accounts - those accounts which, if compromised, could cause the most damage - and take proactive steps to secure them. User Assessment Baselines make it easy to know when new accounts are added, or an account's privileges are modified. Use OCI events to receive proactive notifications when a database deviates from its baseline.
  • Activity Auditing: Understanding and reporting on user activity, data access, and changes to database structures supports regulatory compliance requirements and can aid in post-incident investigations. Activity auditing collects audit records from databases and helps you manage audit policies. Audit insights make it easy to identify inefficient audit policies, while alerts based on audit data proactively notify you of risky activity.
  • Sensitive Data Discovery: Knowing what sensitive data is managed in your applications is critical for security and privacy. Data discovery scans your database for over 150 different types of sensitive data, helping you understand what types and how much sensitive data you are storing. Use these reports to formulate audit policies, develop data masking templates, and create effective access control policies.
  • Data Masking: Minimizing the amount of sensitive data your organization maintains helps you meet compliance requirements and satisfy data privacy regulations. Data masking helps you remove risk from your non-production databases by replacing sensitive information with masked data. With reusable masking templates, over 50 included masking formats, and the ability to easily create custom formats for your organization's unique requirements, data masking can streamline your application development and testing operations.

*Includes 1 million audit records per database per month if using the audit collection for Activity Auditing

Get Started

To get started you just need to register your database with Oracle Data Safe:

  • Pre-requisite: Obtain the necessary Identity and Access Management (IAM) permissions to register your target database in Data Safe: Permissions to Register an Oracle Cloud Database with Oracle Data Safe
  • Connecting your database to Data Safe

    • If your database is running in a private virtual cloud network (VCN), you can connect it to Data Safe via a Data Safe private endpoint.

      The private endpoint essentially represents the Oracle Data Safe service in your VCN with a private IP address in a subnet of your choice.

      You can create the private endpoint in the VCN of your database either before the registration or during the registration process. You can find more details on how to create the private endpoint under Create an Oracle Data Safe Private Endpoint.

  • Register your database in Data Safe

Using Oracle Data Safe

Once your database is registered in Data Safe, you can leverage all features.

Security Assessment

Security Assessments are automatically scheduled once a week in Data Safe and provide an overall picture of your database security posture. It analyzes your database configurations, users and user entitlements, as well as security policies to uncover security risks and improve the security posture of Oracle Databases within your organization. A security assessment provides findings with recommendations for remediation activities that follow best practices to reduce or mitigate risk.

Start by reviewing the security assessment report for your database: View the latest assessment for a target database

You can find more details on Security Assessment under Security Assessment Overview.

User Assessment

User Assessments are automatically scheduled once a week in Data Safe and help you to identify highly privileged user accounts that could pose a threat if misused or compromised. User Assessment reviews information about your users in the data dictionaries on your target databases and then calculates a potential risk for each user, based on system privileges and role grants.

You can find more details on User Assessment under User Assessment Overview.

Data Discovery

Data Discovery searches for sensitive columns in your database. It comes with over 150 pre-defined sensitive types and you can also create your own sensitive types. You tell Data Discovery if you want to scan your entire database or just certain schemas and what type of sensitive information to look for, and it finds the sensitive columns that meet your criteria and stores them in a sensitive data model (SDM).

Start by discovering sensitive data in your database: Create Sensitive Data Models

You can find more details on Data Discovery under Data Discovery Overview.

Data Masking

Data masking, also known as static data masking helps you to replace sensitive or confidential information in your non-production databases with realistic and fully functional data with similar characteristics as the original data. Data Safe comes with pre-defined masking formats for each of the pre-defined sensitive types that can also be leveraged for your own sensitive types.

Once you know where sensitive data is stored in your database (for instance after running Data Discovery in Data Safe), you can start by creating a masking policy: Create Masking Policies

After you created a masking policy and copied your production database, you can mask your non-production copy: Mask Sensitive Data on a Target Database

You can find more details on Data Masking under Data Masking Overview.

Activity Auditing

Activity Auditing in Oracle Data Safe helps to ensure accountability and improve regulatory compliance. With Activity Auditing, you can collect and retain audit records per industry and regulatory compliance requirements and monitor user activities on Oracle databases with pre-defined reports and alerts. For example, you can audit access to sensitive data, security-relevant events, administrator and user activities, activities recommended by compliance regulations like the Center for Internet Security (CIS), and activities defined by your own organization.

If you are using the audit collection in Data Safe, up to 1 million audit records per target database per month are included for your Cloud@Customer database.

To use activity auditing, start the audit trail for your target database in Data Safe: Start an Audit Trail

Once the audit trail is started, you can monitor and analyze your audit data with pre-defined audit reports: View a Predefined or Custom Audit Report

You can find more details on Activity Auditing under Activity Auditing Overview.
