Which option is not a required element of change control procedures for patches?

• A. Direct deployment without testing
• B. Documentation of impact
• C. Documented change approval by authorized parties
• D. Back-out procedures

Answer: (A)

Implementing patches safely relies on a formal change-control process that includes evaluating the patch’s impact, obtaining formal authorization, and having a rollback plan. Testing the patch in a controlled environment helps confirm it resolves the vulnerability without introducing new issues, and it provides evidence that the change won’t disrupt critical services. Documentation of the expected impact keeps stakeholders informed, and authorized change approvals ensure accountability and traceability. Direct deployment without testing is not a supported element of change control. Skipping testing bypasses the evaluation step, increasing the risk of compatibility problems, outages, or unseen side effects. That’s why the other elements—documenting impact, getting documented approval by authorized parties, and having back-out procedures—are considered required components.
