Testing patches before deployment is perhaps the most critical step in the patch management process. Although patch management has become a reliable solution for end-point vulnerability protection, organizations often fail to realize the impact of incorrectly patched applications and failed updates. As much as we want applications updated, we need to be careful about how we introduce a new patch update into the application environment.
Think of the below possibilities that need be analyzed before deploying the patch update.
Will the patch be successfully deployed in the target environment?
Will the patch be compatible with the OS platform?
Will the patch cause any unprecedented issues on the target platform post-deployment?
How will you get to know if the patch deployment has failed?
Failing to analyze these questions could invite more complaints and issues from end-users and cause administrative headaches to IT admins.
Best Practices for Pre-Deployment Patch Testing
The goal of testing patches before deployment is to ensure the system's applications and operations are not impacted, and business services are not interrupted. Proper testing of security updates is an industry-standard best practice that allows you to understand the possible impact of the patch update on your target environment.
Pre-deployment patch testing should consist of the following:
Simulate test cases and check if the patches are getting deployed successfully on the target platform(s)
Compare application performance before and after patch deployment and check if there are any issues
Test if other applications running on the target environment are impacted by the patch update
Ensure that if the patch is successfully removed, no application or system issues will occur
Incorporate patch testing as part of your IT security risk assessment plan
Additionally, as a post-deployment check, implement a mechanism to notify you of failed patch deployment.
