We are looking for historical audit trails for policies. This way, we can see which admin made a configuration change with a date/time stamp. Our auditors would prefer this so we can show a history of any changes related to controls.
Unfortunately, internal audit records for policy settings changes are not available. I would suggest only providing access to a limited number of admins to your group policy and make it known that changes should only be made after a discussion and consensus from other policy admins.
