Assessment Title

Rule Text

The maximum password age must be configured to 60 days or less.

Description

Discussion Text

The longer passwords are in use, the greater the opportunity for someone to gain unauthorized knowledge of them. Scheduled changing of passwords hinders the ability of unauthorized users to crack passwords and gain access to a system.

How this relates to the STIG checklist: STIG vs SCAP benchmark.

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 windows_7 target this check assesses.

# oval:mil.disa.fso.windows:def:3653
$maxPasswordAge = (Get-ItemProperty -Path 'HKLM:\System\CurrentControlSet\Services\Ntlanman\Parameters' -Name 'MaxPasswordAge').MaxPasswordAge.Days
if ($maxPasswordAge -le 60 -and $maxPasswordAge -ne 0) { Write-Output "PASS"; Exit 0 } else { Write-Output "FAIL"; Exit 1 }

Remediation

Configure the policy value for Computer Configuration >> Windows Settings >> Security Settings >> Account Policies >> Password Policy >> "Maximum Password Age" to "60" days or less (excluding "0", which is unacceptable).
