Microsoft Windows PAW STIG Version Comparison
Microsoft Windows PAW Security Technical Implementation Guide
There are 5 differences between versions v1 r3 (May 15, 2020) (the "left" version) and v2 r2 (May 31, 2022) (the "right" version).
Check WPAW-00-001050 was changed between these two versions. Green, underlined text was added, red, struck-out text was removed.
Device Guard Code Integrity Policy must be used on the Windows PAW to restrict applications that can run on the system (Device Guard Code Integrity Policy).
Note: This requirements requirement is Not Applicable (NA) if the HBSS ePO Endpoint Security Solution (ESS) managed system is used on the PAW and application white listing is enforced. Verify enforced. Verify Device Guard is enforcing a code integrity policy to restrict authorized applications. Run "PowerShell" with elevated privileges (run as administrator). Enter the following: "Get-CimInstance -ClassName Win32_DeviceGuard -Namespace root\Microsoft\Windows\DeviceGuard | FL *codeintegrity*" If "CodeIntegrityPolicyEnforcementStatus" does not have a value of "2" indicating "Enforced", this is a finding. (For reference: 0 - Not Configured; 1 - Audit; 2 - Enforced) Alternately: - Run "System Information". - Under "System Summary", verify the following: If "Device Guard Code Integrity Policy" does not display "Enforced", this is finding.
A main security architectural construct of a PAW is to restrict non-administrative applications and functions from the PAW workstation. Many standard user applications and functions, including email processing, Internet browsing, and using business applications, can increase the security risk to the workstation. These apps and functions are susceptible to many security vulnerabilities, including phishing attacks and embedded malware. This increased risk is not acceptable for the highly privileged activities of a PAW.
Implement a whitelist of authorized PAW applications using Device Guard. See the Device Guard Deployment Guide (https://docs.microsoft.com/en-us/windows/device-security/device-guard/device-guard-deployment-guide) for deployment information and hardware requirements and the IAD Device Guard document "Implementing a Secure Administrative Workstation using Device Guard" at https://github.com/iadgov/Secure-Host-Baseline/tree/master/Device%20Guard.
