Which of the following best describes post-incident analysis?

Post-incident analysis primarily focuses on evaluating the measures taken during an incident response to identify strengths and areas for improvement. By thoroughly analyzing the incident response process, organizations can gather valuable insights into what worked effectively and what did not. This analysis is crucial for refining future incident response strategies, enhancing preparedness, and mitigating similar incidents in the future.

The core goal of post-incident analysis is continuous improvement in an organization’s security posture, which aligns perfectly with option B. This allows teams to adapt their approaches based on real-world experiences, ensuring that they are better equipped to handle incidents as they arise.

In contrast, a review of assets used during the incident pertains more to inventory management and risk assessment than improving the response process. Although asset review holds significance, it doesn't encompass the broader scope of post-incident analysis, which includes lessons learned beyond just the assets involved. Likewise, confirming incident readiness is related to proactive preparedness rather than the reflective and analytical nature of post-incident assessments. Finally, while cybersecurity assessments might conclude with a sort of review, the phrase “final step” does not adequately capture the ongoing, iterative nature of post-incident analysis, which is a crucial part of learning and adapting rather than a one-time evaluation.
