ISC2 Certified Secure Software Lifecycle Professional (CSSLP) Practice Question
Your DevSecOps team receives notification of a critical security patch for an open-source library used by a production microservice. To follow a secure patch management process, which action should you take before integrating the vendor patch into the main branch?
Roll back the microservice to its previous stable version until the patch is available.
Conduct a compatibility and risk assessment in a controlled test environment.
Deploy the patch directly to the production environment and monitor for anomalies.
Announce the patch to customers and schedule user acceptance testing.
A secure patch management workflow begins with validating the patch's relevance and safety. After a vendor releases a fix, the first responsibility is to determine whether the patch applies to your environment, assess the severity of the underlying vulnerability, and test the update in an isolated environment for functional and security regressions. Only after this analysis confirms that the patch addresses the issue without introducing new problems should it be approved for promotion to staging and, ultimately, production. Skipping evaluation and deploying immediately risks outages or new vulnerabilities; announcing downtime or rolling back code does not assess the patch itself and may delay needed remediation.
