Follow Patch Tuesday Best Practices for Optimal Results
Patch Tuesday, marked by the release of Microsoft’s software product fixes, can create anxiety for Windows system administrators. While Microsoft’s patches are typically reliable, there have been instances of buggy updates causing widespread issues. To navigate these challenges, admins are advised to implement a solid patch management strategy that mitigates potential risks.
Developing a Patch Management Plan
A patch management plan defines the policy and schedule for deploying new patches, typically requiring deployment within 30 days, with critical patches needing action within 15 days. The IT department should utilize this period to verify patch integrity and monitor feedback from other organisations regarding patch performance.
Building a Systems and Software Inventory
Creating an accurate inventory of all IT infrastructure is crucial for effective patch management. Automated tools such as Microsoft Configuration Manager and PDQ Inventory can simplify this process. It’s essential to record software versions and dependencies to anticipate how patches might interact.
Testing Windows Patches
Testing patches in a virtual environment mirroring the production setup is advisable to mitigate risks before broader deployment. Following this, patches should be tested on a sample of systems to ensure stability before full rollout.
Developing a Patching Priority List
Prioritising patches based on their risk and the vulnerability they address is vital. Critical systems with external exposure should receive patches before internal systems. If urgent patching is required, ensure backups are available and a rollback procedure is in place.
Automating the Patch Deployment Process
Automation reduces the manual labour involved in patch management and decreases human error. Tools from Microsoft and other vendors can streamline the patching process across systems effectively.
Checking for Potential Issues
After deploying patches, it is important to verify their success and monitor for adverse effects. Increased help desk tickets, system resource spikes, and unusual events in logs are indicators that a patch may have caused issues.
Conclusion
Regularly staying updated with Microsoft resources and engaging with the IT community can greatly aid in smooth patch management. By following thorough practices and maintaining robust fallback procedures, sys admins can minimise disruptions and ensure system stability on Patch Tuesday.
Key Points
- Implement a patch management plan that defines deployment schedules and integrity checks.
- Utilise automated tools for creating a comprehensive IT inventory, including software versions and dependencies.
- Test patches in a controlled, virtual environment before broader deployment.
- Prioritise patch applications based on risk and system exposure.
- Automate the patch deployment process to reduce manual errors and time investment.
- Monitor deployed patches for problems using reporting tools and systems checks.
