Post-Incident Analysis
Post-incident analysis is the examination and evaluation of the events and actions taken during and after a security incident. This process helps identify areas of improvement, update security policies, and enhance the organization’s incident response capabilities. A detailed analysis of a security incident can reveal attack vectors, vulnerabilities exploited by the attacker, and the potential cause of the incident. By performing a comprehensive review of an incident, organizations can learn valuable lessons from the experience, which can then be applied to strengthen the overall security posture and response capabilities. This analysis also helps maintain compliance with industry standards and legal requirements.
