Describe the incident response lifecycle

S
Situation
Every organization needs a structured approach to handling security incidents.
T
Task
Outline the phases of incident response per NIST SP 800-61.
A
Action
NIST IR lifecycle: 1) Preparation (tools, plans, training), 2) Detection and Analysis (identify, triage, investigate), 3) Containment, Eradication, Remediation (stop the bleeding, remove threat, fix root cause), 4) Post-Incident Activity (lessons learned, documentation, process improvement). Each phase has specific deliverables, roles, and escalation criteria.
R
Result
Demonstrating knowledge of the full lifecycle shows you can handle incidents from detection through closure. Mentioning specific tools and processes at each phase adds credibility.
