The DBMS must generate audit records when unsuccessful attempts to modify privileges/permissions occur.

Description
Failed attempts to change the permissions, privileges, and roles granted to users and roles must be tracked. Without an audit trail, unauthorized attempts to elevate or restrict privileges could go undetected. In an SQL environment, modifying permissions is typically done via the GRANT, REVOKE, and DENY commands. To aid in diagnosis, it is necessary to keep track of failed attempts in addition to the successful ones.

If there is no distinction in the DBMS's security architecture between modifying permissions on the one hand, and adding and deleting permissions on the other hand, this is not a finding. Review DBMS documentation to verify that audit records can be produced when the system denies or fails to complete attempts to modify privileges/permissions/role membership. 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 modify privileges/permissions/role membership. 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 modify privileges/permissions/role membership. If they are not produced, this is a finding.
