A proposed application update successfully passes all operational performance and usability testing phases. Despite this, deploying the update introduces a severe vulnerability. Which critical validation step was improperly omitted from the Change Advisory Board (CAB) review process before final approval?
Pick A–D or press 1–4, then give this panel ten seconds: the verdict, and why each of the four options is right or wrong.
Approving changes based solely on functional test results without performing security validation or threat modeling introduces significant risk. A change may work operationally but contain vulnerabilities.
- AMore functional testing repeats what already passed; it does not look for security weaknesses.
- BA failover test checks recoverability, not whether the change introduces a vulnerability.
- CCorrect: a security impact assessment with threat modeling is the CAB step that catches vulnerabilities functional tests miss.
- DDocumentation updates support users but do nothing to assess the security of the change.
