Assessment Title

Rule Text

Device driver updates must only search managed servers, not Windows Update.

Description

Discussion Text

Uncontrolled system updates can introduce issues to a system. Obtaining update components from an outside source may also potentially provide sensitive information outside of the enterprise. Device driver updates must be obtained from an internal source.

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

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 ms_windows_2012_and_2012_r2_dc target this check assesses.

# OVAL Definition: oval:mil.disa.fso.windows:def:4451
$regPath = "HKLM:\Software\Policies\Microsoft\Windows\DriverSearching"
$regKey = "DriverServerSelection"
$regValue = "Specify the search server for device driver updates"

Remediation

Configure the policy value for Computer Configuration -> Administrative Templates -> System -> Device Installation -> "Specify the search server for device driver updates" to "Enabled" with "Search Managed Server" selected.
