Changes to DBMS security labels should be audited.

SV-24442r2_rule Changes to DBMS security labels should be audited.

Vulnerability discussion

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.

Check content

If no data is identified as being sensitive or classified by the Information Owner, in the System Security Plan or in the AIS Functional Architecture documentation, this is not a finding. If security labeling is not required, this is not a finding. If no sensitive or classified data is identified by the Information Owner as requiring labeling in the System Security Plan and/or AIS Functional Architecture documentation, this is not a finding. Run the SQL statement: select * from dba_sa_audit_options; If no records are returned or if output from the SQL statement above does not show classification labels being audited as required in the System Security Plan, this is a finding.

Fix text

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.

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
