O121-BP-026200 - Changes to DBMS security labels must be audited.

Information

Some DBMS systems provide the feature to assign security labels to data elements. If labeling is required, implementation options include the Oracle Label Security package, or a third-party product, or custom-developed functionality. The confidentiality and integrity of the data depends upon the security label assignment where this feature is in use. Changes to security label assignment may indicate suspicious activity.

Solution

Define the policy for auditing changes to security labels defined for the data.

Document the audit requirements in the System Security Plan and configure database auditing in accordance with the policy.

If using Standard Auditing:
If there is no Unified Auditing policy deployed to audit changes to security labels, the create one using the following syntax:
SA_AUDIT_ADMIN.AUDIT (
policy_name IN VARCHAR2,
users IN VARCHAR2 DEFAULT NULL,
audit_option IN VARCHAR2 DEFAULT NULL,
audit_type IN VARCHAR2 DEFAULT NULL,
success IN VARCHAR2 DEFAULT NULL);

For additional information on creating audit policies, refer to the Oracle Database Security Guide
http://docs.oracle.com/database/121/OLSAG/packages.htm#i1011868

If Unified Auditing is used:
To ensure auditable events are captured:
Link the oracle binary with uniaud_on, and then restart the database. Oracle Database Upgrade Guide describes how to enable unified auditing.
Reference V-61625 for information on how to configure a policy to audit changes to security label assignments.
