The primary objective of a post-incident review of an information security incident is to identify the root cause of the incident and determine what can be done to prevent a similar incident from happening in the future. This process helps organizations to learn from past incidents and make improvements to their security posture to reduce the risk of future incidents. By conducting a thorough post-incident review, organizations can identify areas for improvement in their security controls, policies, and procedures, and implement changes to prevent similar incidents from happening in the future. Other important objectives of a post-incident review may include updating the risk profile, minimizing impact, and determining the impact of the incident, but the main focus should be on identifying ways to prevent recurrence.
