Assessment Title

Rule Text

The system is configured to permit storage of passwords and credentials.

Description

Discussion Text

This setting controls the storage of passwords and credentials for network authentication on the local system. Such credentials should never be stored on the local machine as that may lead to account compromise.

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_7 target this check assesses.

# OVAL Definition: oval:mil.disa.fso.windows:def:3705
$registryPath = "HKLM:\System\CurrentControlSet\Control\Lsa"
$registryName = "DisableDomainCreds"
$expectedValue = 1
if (-not (Test-Path $registryPath)) { exit 0 }
$registryValue = (Get-ItemProperty -Path $registryPath -Name $registryName -ErrorAction SilentlyContinue).$registryName
if ($registryValue -eq $null -or $registryValue -ne $expectedValue) { Write-Output "FAIL"; exit 1 } else { Write-Output "PASS"; exit 0 }

Remediation

Configure the policy value for Computer Configuration -> Windows Settings -> Security Settings -> Local Policies -> Security Options -> “Network access: Do not allow storage of passwords and credentials for network authentication” to “Enabled”.
