Incident Response isn't just about reacting to alerts; it's a disciplined, six-phase lifecycle designed to manage chaos, preserve evidence, and restore business operations. In this foundational module of the Incident Response path, we break down the industry-standard PICERL framework (Preparation, Identification, Containment, Eradication, Recovery, and Lessons Learned).

You will learn how to build IR readiness before the breach happens, execute surgical triage, apply the right containment strategy without destroying volatile evidence, and conduct post-incident reviews that actually improve your security posture. Stop treating breaches as unpredictable emergencies and start managing them as repeatable, operational processes.
