Domain Controllers Managed by Illegitimate Users

critical

Description

Despite the number of Active Directory assets, the Domain Controllers are the most sensitive as they store all of these assets data (including authentication secrets like the users' passwords).
Only legitimate administrative accounts should be able to manage them.

Solution

The Domain Controllers (DCs) require strict access rights. Allow only highly privileged user accounts to manage DC objects or link new group policies.
