Incident Response Lifecycle

The incident response lifecycle consists of six key phases that organizations must follow to effectively manage security incidents.

1. Preparation

Develop incident response capabilities, train staff, and establish procedures before incidents occur.

2. Identification

Detect and analyze security events to determine if they constitute a security incident.

3. Containment

Limit the scope and magnitude of the incident to prevent further damage.

4. Eradication

Remove the threat and restore affected systems to a secure state.

5. Recovery

Restore systems and services to normal operation while monitoring for signs of compromise.

6. Lessons Learned

Document lessons learned and update incident response procedures for future improvements.
