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_10 target this check assesses.

# OVAL Definition: oval:mil.disa.stig.windows10:def:220959
$allowedGroups = "Administrators", "Users"
$localPolicy = Get-CimInstance -ClassName Win32_LocalSystemGroupUserRightAssignment -Filter "Right='Allow log on locally'"
if ($localPolicy -eq $null) { exit 0 }
$assignedGroups = $localPolicy.UserName -split ","
foreach ($group in $allowedGroups) {
    if ($assignedGroups -notcontains $group) { exit 1 }
}
exit 0
