Assessment Title

Rule Text

Systems must be at supported service pack (SP) or release levels.

Description

Discussion Text

Systems at unsupported service packs or releases will not receive security updates for new vulnerabilities and leaves them subject to exploitation. Systems must be maintained at a service pack level supported by the vendor with new security updates.

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:3862
$OSBuild = (Get-ItemProperty -Path 'HKLM:\SOFTWARE\Microsoft\Windows NT\CurrentVersion').CurrentBuildNumber
if ($OSBuild -ge 7601) { Write-Output "PASS"; Exit 0 } else { Write-Output "FAIL"; Exit 1 }

Remediation

Update the system to a supported service pack.

				Application of new service packs should be thoroughly tested before deploying in a production environment.
