Assessment Title

Rule Text

Users are not warned in advance that their passwords will expire.

Description

Discussion Text

This setting configures the system to display a warning to users telling them how many days are left before their password expires. By giving the user advanced warning, the user has time to construct a sufficiently strong password.

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 Definition: oval:mil.disa.fso.windows:def:3693
$registryPath = "HKLM:\Software\Microsoft\Windows NT\CurrentVersion\Winlogon"
$registryValueName = "PasswordExpiryWarning"
$expectedValue = 14
$registryValue = (Get-ItemProperty -Path $registryPath -Name $registryValueName -ErrorAction SilentlyContinue).$registryValueName
if ($registryValue -ge $expectedValue -or $registryValue -eq $null) { Write-Output "PASS"; Exit 0 } else { Write-Output "FAIL"; Exit 1 }

Remediation

Configure the policy value for Computer Configuration -> Windows Settings -> Security Settings -> Local Policies -> Security Options -> “Interactive Logon: Prompt user to change password before expiration” to “14” days or more.
