Title

Windows Server 2025 permissions on the Active Directory data files must only allow system administrators (SAs) access.

Control

This applies to domain controllers. It is not applicable for other systems. Run "Regedit". Navigate to "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\NTDS\Parameters". Note the directory locations in the values for: Database log files path DSA Database file By default, they will be \Windows\NTDS. If the locations are different, run the following for each: Open "command prompt (Admin)". Navigate to the NTDS directory (\Windows\NTDS by default). Run "icacls *.*". If the permissions on each file are not as restrictive as the following, this is a finding: NT AUTHORITY\SYSTEM:(I)(F) BUILTIN\Administrators:(I)(F) (I) - permission inherited from parent container (F) - full access

Discussion

Improper access permissions for directory data-related files could allow unauthorized users to read, modify, or delete directory data or audit trails. Satisfies: SRG-OS-000324-GPOS-00125, SRG-OS-000206-GPOS-00084
