Ensure 'Enable computer and user accounts to be trusted for delegation' is set to 'No One'

HighLevel 1Automatedwindows

Description

This policy setting allows users to change the Trusted for Delegation setting on a computer object in Active Directory. Abuse of this privilege could allow unauthorized users to impersonate other users on the network. The recommended state for this setting is: No One. Note: This user right is considered a "sensitive privilege" for the purposes of auditing.

How it is checked

$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*SeEnableDelegationPrivilege\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 { $_ } }); if ((($have | Sort-Object -Unique) -join ',') -eq '') { 'compliant' } else { 'non-compliant: ' + ($have -join ',') }
