About this chapter
What this chapter covers
Security Operations and Incident Response is worth about 17 percent of the CC exam. It covers the daily work of protecting data, watching for threats, responding when something goes wrong, keeping assets under control and testing defenses.
It covers data security (classification, labeling, masking, sanitization and encryption, including quantum-resistant cryptography), security operations (logging and monitoring, event triage, threat actors, threat intelligence and threat frameworks), incident response (the incident response plan, data handling and exercises), asset protection (asset lifecycle, end-of-life systems, configuration and change management) and security testing (red, blue and purple teams, vulnerability scanning, static and dynamic analysis, threat modeling and physical penetration testing). The 2026 outline adds AI themes such as AI in SIEM tools, staff pasting data into public AI services and AI model changes under change control.
How the topics fit together
CC questions ask what to do first in an incident, which control protects data in a given state, and which test or team fits a goal.
In an incident, the first step is to confirm and assess what happened before taking drastic action or making announcements.
