Part IV: Protect

The Protect Function uses safeguards to manage cybersecurity risk. AI changes what must be protected and how: agents act with credentials and synthetic media attacks approvals.

Chapter 14 protects identities and access for people, machines and agents (PR.AA). Chapter 15 builds resilience to AI-generated deception and trains staff to supervise security AI (PR.AT). Chapter 16 protects data and platforms (PR.DS, PR.PS), and Chapter 17 makes infrastructure resilient against machine-speed attacks (PR.IR).

What you will learn in this part:

• How identity and approvals change when agents act and deepfakes deceive
• Which controls protect AI systems and security data
