This diagram represents the incident response lifecycle that security operations teams follow to handle breaches and outages. It walks through the established phases that turn a chaotic event into a coordinated process. The stages include preparation, detection and analysis, containment, eradication, recovery, and a post-incident review, each tied to the central coordination of the response team.
SOC analysts, security managers, and compliance officers use this incident response flow diagram to document runbooks, train responders, and satisfy frameworks like NIST and SANS. It is ideal for tabletop exercises, audit evidence, and aligning stakeholders on who acts at each phase of an incident.
Great for
- Security runbooks
- Tabletop exercises
- Compliance audits
- SOC training
- Executive briefings
Frequently asked questions
What is an incident response flow?+
It is the structured sequence a security team follows when handling an incident, moving from preparation and detection through containment, eradication, recovery, and a final review to limit damage and improve defenses.
What are the phases of incident response?+
The common NIST phases are preparation, detection and analysis, containment, eradication and recovery, and post-incident activity. SANS uses a similar six-step model.
Why document incident response as a diagram?+
A visual flow clarifies who acts at each phase, speeds up decision-making during a real event, and provides audit-ready evidence for compliance frameworks.
What is the goal of the post-incident review?+
It captures lessons learned, updates runbooks, and feeds improvements back into the preparation phase so the team responds faster next time.
