In today’s digital landscape, security is a paramount concern for any organization. Keeping your Windows Server environment secure and up-to-date is critical in protecting against vulnerabilities. Automating security updates is an effective way to ensure that your server remains fortified against threats without manual intervention. This guide by WafaTech will walk you through enabling and configuring Windows Server Update Services (WSUS) and Windows Update settings for automation.

What is WSUS?

Windows Server Update Services (WSUS) is a free add-on for Windows Server that allows IT administrators to manage the distribution of updates released through Microsoft Update to computers in a corporate environment. WSUS provides several benefits:

  • Control over the updates deployed to your server.

  • Central management of updates.

  • Reduced bandwidth usage.

Prerequisites

Before setting up WSUS, ensure that:

  • You have a Windows Server installation (preferably Windows Server 2016 or later).

  • You have administrative privileges on the server.

  • The server is connected to the internet.

Step 1: Installing WSUS

  1. Open Server Manager: Click on the Start button, type "Server Manager," and press Enter.

  2. Add Roles and Features: In the Server Manager dashboard, click on “Add Roles and Features”.

  3. Role-Based or Feature-Based Installation: Select "Role-based or feature-based installation" and click Next.

  4. Select Server: Choose the server you want to install WSUS on.

  5. Select Server Roles: Find and check “Windows Server Update Services.” Click Next.

  6. Add Features: You may be prompted to add additional features. Accept by clicking “Add Features” when prompted and click Next.

  7. Role Services: In the role services window, select the needed components, including “WSUS Services”. Proceed by clicking Next.

  8. Database Options: Choose either to use Windows Internal Database or SQL Server if installed, then click Next.

  9. Content Location: Specify the folder where WSUS will store updates. It’s advisable to choose a drive with ample space, typically at least 10GB.

  10. Finish Installation: Confirm all selections and click Install. Once it’s complete, click Close.

Step 2: Configuring WSUS

  1. Open WSUS Console: Go to Tools in Server Manager and open Windows Server Update Services.

  2. Initial Configuration Wizard: Follow the configuration wizard, beginning with choosing the Microsoft Update servers to synchronize.

  3. Select Products: Select the Microsoft products that will receive updates (e.g., Windows Server, Microsoft Office).

  4. Select Classifications: Choose which classifications of updates to download (e.g., Critical Updates, Security Updates).

  5. Set Sync Schedule: Configure when WSUS should check for updates (e.g., daily, weekly).

  6. Finish and Sync: Complete the wizard and click on “Synchronize” to initiate the first sync.

Step 3: Configuring Group Policy

To automate the deployment of updates on client machines and servers within your domain:

  1. Open Group Policy Management: Press Windows + R, type gpmc.msc, and press Enter.

  2. Create a New GPO: Right-click on the organizational unit (OU) where the servers reside and select “Create a GPO in this domain, and Link it here.”

  3. Edit the GPO: Right-click the newly created GPO and select “Edit”.

  4. Navigate to Update Settings:

    • Computer Configuration > Policies > Administrative Templates > Windows Components > Windows Update.

  5. Configure Policies:

    • Enable "Configure Automatic Updates" and select desired options (e.g., Auto download and schedule the install).

    • Set “Specify intranet Microsoft update service location” to point to the WSUS server. For example:

  6. Close the Editor: Close the Group Policy Management Editor and force an update with gpupdate /force on the server.

Step 4: Monitoring Updates

Regularly monitor update status and deployment:

  1. Check WSUS Console: Open the WSUS console to see the status of updates and deployment.

  2. Reporting: Use built-in reports within WSUS for tracking update compliance.

  3. Event Viewer: Check the Event Viewer on clients/servers for any update-related events.

Conclusion

Automating security updates in Windows Server is a critical step in maintaining a secure infrastructure. By following this guide, you can reduce the risk of vulnerabilities while ensuring that your systems are consistently updated. Regular monitoring of update status will help to maintain organizational security policies effectively.
