Summary
This guide outlines the essential phases of incident response planning as defined by the SANS Institute’s Incident Handling Process. It describes the six phases: Preparation, Identification, Containment, Eradication, Recovery, and Lessons Learned. In the Preparation phase, it emphasizes the importance of developing an Incident Response Plan (IRP), assembling a response team, training employees, maintaining security tools, and regularly testing backups. The Identification phase focuses on the need for effective monitoring systems to detect incidents and classify them based on severity. The Containment phase details strategies for limiting damage while preserving evidence, including short-term and long-term containment measures. In the Eradication phase, the guide explains how to eliminate threats and patch vulnerabilities. The Recovery phase discusses the safe restoration of systems and the need for close monitoring. Finally, the Lessons Learned phase encourages conducting post-incident reviews to improve future responses and update documentation.
