The provided text introduces the NIST Incident Response Lifecycle, a structured methodology for managing security incidents as outlined in NIST Special Publication 800-61. This lifecycle is broken down into four crucial phases: Preparation, which emphasizes readiness through planning and tooling; Detection & Analysis, focused on identifying and understanding incidents; Containment, Eradication, & Recovery, detailing steps to stop attacks, remove threats, and restore systems; and Post-Incident Activity, centered on learning and improving security posture. The content uses a podcast format to explain these phases, offering real-world examples, actionable steps, and tips for effective incident handling. The aim is to provide a practical understanding of a widely recognized framework for responding to cybersecurity incidents.
