Assessment Title

Rule Text

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

Description

Discussion Text

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

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

$passwordPolicy = Get-CimInstance -ClassName Win32_LocalUser -Filter "LocalAccount='true'"
if ($passwordPolicy -eq $null) { exit 1 }

if (($maxPasswordAge.Value -le 5184000) -and ($maxPasswordAge.Value -gt 0)) { exit 0 }
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).
