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.
Incident Response Team Structure
A well-structured incident response team ensures clear roles and responsibilities during security incidents.

- • Medium (P2): Response within 4 hours, limited business impact
- • Low (P3): Response within 24 hours, minimal business impact
Communication and Escalation Procedures
Clear communication and escalation procedures ensure that stakeholders are informed appropriately and decisions are made at the right level.
Internal Communication
- • Team notifications
- • Executive briefings
- • Employee updates
- • Status reports
External Communication
