Assessment Title

Rule Text

Minimum password age does not meet minimum requirements.

Description

Discussion Text

Permitting passwords to be changed in immediate succession within the same day, allows users to cycle passwords through their history database. This enables users to effectively negate the purpose of mandating periodic password changes.

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

SCC Automation Reference

The reconstructed evaluation script behind this rule's OVAL check(s) — every module a compound check combines, with this rule's own concrete values and DISA's SCC tool's real per-module mechanism curated from static teardown of SCC releases.

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_vista target this check assesses.

# OVAL Definition: oval:mil.disa.fso.windows:def:420
$passwordPolicy = Get-CimInstance -ClassName Win32_LocalUserAccount
if ($passwordPolicy -ne $null -and $passwordPolicy.PasswordRequired -eq $true)
{
    $policy = Get-CimInstance -ClassName Win32_PasswordPolicy
    if ($policy -ne $null -and [int]$policy.MinimumPasswordAge -ge 1)
    {
        Write-Output "PASS"
        Exit 0
    }
}
Write-Output "FAIL"
Exit 1

Remediation

Configure the Minimum Password Age so that it is a minimum of "1".
