Rule Text

Auditing Access of Global System Objects must be turned off.

Description

Discussion Text

This setting prevents the system from setting up a default system access control list for certain system objects, which could create a very large number of security events, filling the security log in Windows and making it difficult to identify actual issues.

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:3679
$registryPath = "HKLM:\System\CurrentControlSet\Control\Lsa\AuditBaseObjects"
$registryValue = (Get-ItemProperty -Path $registryPath -ErrorAction SilentlyContinue).AuditAccess
if ($registryValue -eq 0) { Write-Output "PASS"; exit 0 } 
Write-Output "FAIL"; exit 1

Remediation

Configure the policy value for Computer Configuration -> Windows Settings -> Security Settings -> Local Policies -> Security Options -> "Audit: Audit the access of global system objects" to "Disabled".
