Without auditing the enforcement of access restrictions against changes to configuration, it would be difficult to identify attempted attacks and an audit trail would not be available for forensic investigation for after-the-fact actions. Enforcement actions are the methods or mechanisms used to prevent unauthorized changes to configuration settings. Enforcement action methods may be as simple as denying access to a file based on the application of file permissions (access restriction). Audit items may consist of lists of actions blocked by access restrictions or changes identified after the fact.
Review DBMS documentation to verify audit records can be produced when the system denies or fails to complete attempts to change the configuration of the DBMS or database(s). If the DBMS is not capable of this, this is a finding. Review the DBMS/database security and audit configurations to verify that audit records are produced when the system denies attempts to change the configuration of the DBMS or database(s). If they are not produced, this is a finding. Review the DBMS/database security and audit configurations to verify that audit records are produced when other errors prevent attempts to change the configuration of the DBMS or database(s). If they are not produced, this is a finding.
Deploy a DBMS capable of producing the required audit records when it denies or fails to complete attempts to change the configuration of the DBMS or database(s). Configure the DBMS to produce audit records when it denies attempts to change the configuration of the DBMS or database(s). Configure the DBMS to produce audit records when other errors prevent attempts to change the configuration of the DBMS or database(s).
