The Incident Response Lifecycle (Phases)
- Preparation: Proactive measures like training, tool setup, and plan development.
- Detection & Analysis: Identifying and confirming a security event as a real incident.
- Containment: Isolating affected systems to stop the attack from spreading.
- Eradication: Removing the root cause, such as malware or attacker access.
- Recovery: Restoring systems and data to normal operation, often from backups.
- Lessons Learned (Post-Incident Activity): Analyzing what happened to improve the IR plan
