Incident Escalation, Forensics, Recovery, and Post-Incident Improvement

This chapter explains what happens after prevention fails and an event must be assessed, escalated, and contained. The ISC focus is on disciplined response, evidence preservation, recovery planning, and learning from failure.

In This Chapter

• Events vs. Incidents: Definition and Escalation explains when a problem becomes a formal incident requiring response.
• Incident Response Plans and Crisis Management covers the structured approach to handling active incidents.
• Forensic Investigations and Chain of Custody addresses evidence preservation and investigative integrity.
• Cyber Insurance as a Risk Mitigation Strategy explains the role and limits of insurance in response planning.
