Rule Text

Windows Server 2022 Deny log on as a service user right on domain-joined member servers must be configured to prevent access from highly privileged domain accounts. No other groups or accounts must be assigned this right.

Description

Discussion Text

Inappropriate granting of user rights can provide system, administrative, and other high-level capabilities. The "Deny log on as a service" user right defines accounts that are denied logon as a service. In an Active Directory Domain, denying logons to the Enterprise Admins and Domain Admins groups on lower-trust systems helps mitigate the risk of privilege escalation from credential theft attacks, which could lead to the compromise of an entire domain. Incorrect configurations could prevent services from starting and result in a denial of service.

How this relates to the STIG checklist: STIG vs SCAP benchmark.

Remediation

Configure the policy value for Computer Configuration >> Windows Settings >> Security Settings >> Local Policies >> User Rights Assignment >> Deny log on as a service to include the following:

Domain systems:
- Enterprise Admins Group
- Domain Admins Group
