Chapter 2 - Implement an Incident Response Process
Post-Incident Review
Conduct a formal post-incident review with all relevant stakeholders, including the incident response team, business unit leaders, and executive management.
Review the timeline of the incident, from initial detection through containment, eradication, and recovery, and identify any gaps or areas for improvement in the incident response process.
Analyze the root cause of the incident, and identify any contributing factors, such as inadequate security controls, lack of employee awareness, or third-party risks.
Develop a set of recommendations for improving the organization's security posture and incident response capabilities based on the lessons learned.
Communicate the lessons learned and planned improvements to employees and
stakeholders, and provide any necessary training or awareness materials.
Continuous Improvement
Implement the recommendations and improvements identified in the post-incident review, and track their progress and effectiveness over time.
Update the organization's incident response plan, policies, and procedures based on the lessons learned and evolving best practices.
Conduct regular exercises and simulations to test and refine the organization's incident response capabilities, and identify any new gaps or areas for improvement.
Monitor the threat landscape and industry trends to stay up-to-date on emerging risks and attack vectors, and adapt the organization's defenses and response strategies accordingly.
