ISACA Certified Information Systems Auditor (CISA) ExamDomain 5: Protection of Information AssetsHard
A CISA is reviewing an organization's security incident management process. During the review, the CISA discovers that while security incidents are logged and initial containment actions are taken, there is no formal process for conducting post-incident reviews or incorporating lessons learned into updated security controls or policies. What is the MOST significant long-term consequence of this deficiency?
- ADifficulty in attracting and retaining cybersecurity talent.
- BElevated risk of reputational damage after major incidents.
- CStagnation of the organization's overall security posture.
- DIncreased regulatory fines due to repeated security breaches.
Show answer & explanationAnswer & explanation
Correct answer: C. Stagnation of the organization's overall security posture.
Without a formal process for post-incident review and integrating lessons learned, the organization fails to adapt and improve its security defenses over time. This leads to a static security posture that cannot effectively counter evolving threats, resulting in stagnation.
Why the other options are wrong
- A. Talent retention might be affected by a poor security program, but it's an indirect consequence, not the most significant long-term impact on the security posture itself.
- B. Reputational damage is a consequence of incidents. The lack of learning means the organization is more likely to suffer repeated incidents, thus making the stagnation of the security posture the more fundamental long-term consequence that leads to such damages.
- D. While possible, fines are often a consequence of breaches, not directly caused by lack of lessons learned, though the lack of learning makes breaches more likely.
Lessons Learned Process
A formal systematic review conducted after security incidents to identify root causes, evaluate response effectiveness, and implement corrective actions to improve future security controls and incident response capabilities.
- Drives continuous improvement of the security program.
- Prevents recurrence of similar incidents.
- Essential for adapting to new threats and vulnerabilities.
