Ensure 'Deny log on locally' to include 'Guests'

HighLevel 1Automatedwindows

Description

This security setting determines which users are prevented from logging on at the computer. This policy setting supersedes the Allow log on locally policy setting if an account is subject to both policies. The recommended state for this setting is to include: Guests. Important: If you apply this security policy to the Everyone group, no one will be able to log on locally.

How it is checked

Audit method: Shell command

shell

$f = Join-Path $env:TEMP ('tmaegis-' + [guid]::NewGuid().ToString() + '.inf'); secedit /export /cfg $f /areas SECURITYPOLICY USER_RIGHTS /quiet | Out-Null; $c = Get-Content $f -ErrorAction SilentlyContinue; Remove-Item $f -Force -ErrorAction SilentlyContinue; $line = $c | Where-Object { $_ -match '^\s*SeDenyInteractiveLogonRight\s*=' } | Select-Object -First 1; $v = if ($line) { ($line -split '=', 2)[1].Trim().Trim('"') } else { $null }; $have = @(if ($v) { $v -split ',' | ForEach-Object { $_.Trim().TrimStart('*') } | Where-Object { $_ } }); $missing = @('S-1-5-32-546') | Where-Object { $have -notcontains $_ }; if ($missing.Count -eq 0) { 'compliant' } else { 'non-compliant: ' + ($have -join ',') }

Expected output: compliant
