Title

The DBMS must generate audit records when unsuccessful attempts to delete privileges/permissions occur. (Cat II impact)

Discussion

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, deleting permissions is typically done via the REVOKE or DENY command. To aid in diagnosis, it is necessary to keep track of failed attempts in addition to the successful ones.

Check Content

Review DBMS documentation to verify that audit records can be produced when the system denies or fails to complete attempts remove, revoke, or deny privileges/permissions/role membership to any user or role. 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 remove, revoke, or deny privileges/permissions/role membership to any user or role. 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 remove, revoke, or deny privileges/permissions/role membership to any user or role. If they are not produced, this is a finding.

Fix Text

Deploy a DBMS capable of producing the required audit records when it denies or fails to complete attempts to remove, revoke, or deny privileges/permissions/role membership to any user or role. Configure the DBMS to produce audit records when it denies attempts to remove, revoke, or deny privileges/permissions/role membership to any user or role. Configure the DBMS to produce audit records when other errors prevent attempts to remove, revoke, or deny privileges/permissions/role membership to any user or role.
