After a recent security breach, the incident response team of a financial institution is tasked with conducting a post-incident review. What is the PRIMARY purpose of discussing and documenting the lessons learned?
To ensure there is a record of the chain of custody for the evidence gathered during the incident response.
To perform a root cause analysis identifying all the vulnerabilities exploited during the incident.
To gather and preserve legal and technical evidence for potential prosecution of the perpetrators.
To improve the incident response process for future occurrences by analyzing the strengths and weaknesses of the response.
Discussing and documenting lessons learned is mainly done to improve the incident response process for future occurrences. It helps the organization to better prepare for, respond to, and recover from incidents by identifying what was successful and what could be improved. Sharing findings across the organization ensures that the knowledge is applied to enhance security posture and prevent similar breaches. Root cause analysis is focused on identifying the underlying cause of the incident, while forensic analysis typically involves a detailed investigation to gather legal evidence after an incident. Chain of custody demonstrates that evidence has been controlled and handled properly, but it isn't a primary purpose for lessons learned in a post-incident review.
