How do organizations create security policies, manage risk, respond to incidents, and ensure compliance in a constantly changing threat environment?
Domains 1–4 teach you how attacks work.
Domain 5 teaches you how organizations protect themselves before attacks happen and recover after they do.
Think of Domain 5 as:
Security is not just firewalls.
It's governance — the rules that hold everything together.
Risk — the probability of loss + impact.
Threat — anything that can exploit a vulnerability.
Vulnerability — a weakness that can be exploited.
