Description

Discussion Text

Inappropriately granting user rights provides 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. The Guests group must be assigned this right to prevent unauthenticated access.

Assessment Script Powered by AISyntax-verified

A standalone PowerShell script to assess this control automatically. Review before running it in your environment.

Syntax-checked as valid PowerShell. Not executed here — running it for real needs the actual ms_windows_server_2025 target this check assesses.

$userRight = Get-CimInstance -ClassName Win32_UserRight -Filter "UserRight = 'SE_DENY_NETWORK_LOGON_NAME'"
if ($userRight -and $userRight.UserName -like "*Guests*") { Write-Output "PASS"; exit 0 } else { Write-Output "FAIL"; exit 1 }

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:
- Guests Group.
