Assessment Title

Rule Text

Windows Server 2022 Deny access to this computer from the network user right on domain-joined member servers must be configured to prevent access from highly privileged domain accounts and local accounts and from unauthenticated access on all systems.

Description

Discussion Text

Inappropriate granting of user rights can provide system, administrative, and other high-level capabilities. The "Deny access to this computer from the network" user right defines the accounts that are prevented from logging on from the network. 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. Local accounts on domain-joined systems must also be assigned this right to decrease the risk of lateral movement resulting from credential theft attacks. The Guests group must be assigned this right to prevent unauthenticated access.

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 access to this computer from the network to include the following:

Domain Systems Only:
- Enterprise Admins group
- Domain Admins group
- "Local account and member of Administrators group" or "Local account" (see Note below)

All Systems:
- Guests group

Note: These are built-in security groups. "Local account" is more restrictive but may cause issues on servers such as systems that provide failover clustering.
