Question 820
A security steering team reviews this situation: A software vendor makes an emergency firewall change but never records the reason or later review. Which action best resolves the specific management need?
Explanation
Correct Answer
Integrate security assessment, approval and validation into operational changes. The specific evidence is that a software vendor makes an emergency firewall change but never records the reason or later review. In practical terms, the team should define impact checks, authorization, testing, rollback and emergency post-change review. Effectiveness can then be demonstrated when change evidence links security assessment to approved deployment and verified results. Without this intervention, the main exposure is new exposures and outages introduced by uncontrolled changes.
Incorrect Answers
Implement risk-prioritized vulnerability evaluation and remediation workflows. This is a plausible intervention for a different ISMS issue, such as when a university patches workstations but leaves public research application servers untracked. It does not directly remedy security in change management in the described case. Here the primary action is to integrate security assessment, approval and validation into operational changes. Case: A software vendor makes an emergency firewall change but never records the reason or later review.
Implement physical and media-handling controls appropriate to information sensitivity. This is a plausible intervention for a different ISMS issue, such as when a legal firm leaves client case records on unattended print trays shared with external visitors. It does not directly remedy security in change management in the described case. Here the primary action is to integrate security assessment, approval and validation into operational changes. Case: A software vendor makes an emergency firewall change but never records the reason or later review.
Establish and enforce risk-appropriate secure configuration baselines. This is a plausible intervention for a different ISMS issue, such as when a factory deploys identical edge devices with factory administrator passwords still active. It does not directly remedy security in change management in the described case. Here the primary action is to integrate security assessment, approval and validation into operational changes. Case: A software vendor makes an emergency firewall change but never records the reason or later review.
