WN22-MS-000060 - Windows Server 2022 must restrict remote calls to the Security Account Manager (SAM) to Administrators on domain-joined member servers and standalone or nondomain-joined systems.

Information

The Windows SAM stores users' passwords. Restricting Remote Procedure Call (RPC) connections to the SAM to Administrators helps protect those credentials.

Solution

Navigate to the policy Computer Configuration >> Windows Settings >> Security Settings >> Local Policies >> Security Options >> Network access: Restrict clients allowed to make remote calls to SAM.

Select 'Edit Security' to configure the 'Security descriptor:'.

Add 'Administrators' in 'Group or user names:' if it is not already listed (this is the default).

Select 'Administrators' in 'Group or user names:'.

Select 'Allow' for 'Remote Access' in 'Permissions for 'Administrators'.

Click 'OK'.

The 'Security descriptor:' must be populated with 'O:BAG:BAD:(A;;RC;;;BA) for the policy to be enforced.

If an application requires this user right, this would not be a finding. Vendor documentation must support the requirement for having the user right. The requirement must be documented and approved by the information system security officer (ISSO).
