Windows Server Supply Chain Guide
GuideProtecting your Windows Server infrastructure from supply chain threats targeting Active Directory, Group Policy, and the Windows Server Update Services (WSUS) pipeline.
Key Features
Defending Windows Server Supply Chains
Windows Servers, especially domain controllers, are crown jewels. A supply chain compromise here has blast radius across your entire domain.
Step 1: Secure WSUS
If you use WSUS, enforce SSL for update delivery and verify update signatures.
Step 2: Protect Group Policy Objects
GPO tampering is a supply chain attack on your configuration. Monitor GPO changes and verify integrity.
Step 3: Enforce Driver Block Lists
Deploy Microsoft's recommended driver block list to prevent known-vulnerable drivers from loading.
Step 4: Enable Secure Boot
All servers should boot with Secure Boot enabled to prevent bootkit supply chain attacks.
Step 5: Validate Certificate Chains
Regularly audit your certificate trust store and remove unnecessary root CAs.
