Module 1: Introduction: Why AI Security Matters
What the module covers. This chapter establishes AI security as a distinct but integrated security discipline. It explains what changes when a system's behavior is learned rather than programmed, why that change creates attack surfaces that classical security controls do not cover, and why an AI system must be secured as a whole socio-technical system rather than as a model in isolation. It introduces the three security layers used throughout the book (model, application, system), the extended set of security properties that AI systems must preserve, the distinction between adversarial and nonadversarial risk, and the idea that security claims require assurance evidence. Later chapters build on every one of these ideas.
Learning objectives (7)
- Explain how deterministic and probabilistic systems differ, and why learned behavior changes the nature of a security specification.
- Distinguish model security, AI application security, and AI system security, and classify a given weakness into the correct layer.
- Distinguish security from safety, privacy, reliability, fairness, and governance, and identify where they overlap.
- Analyze an AI system as a socio-technical system by identifying its layers, assets, and trust boundaries.
- Differentiate adversarial attacks, misuse, and accidental failure, and explain why each requires a different response.
- Describe the AI lifecycle at a high level and explain why security controls must attach to lifecycle stages.
- Evaluate a security claim by asking what control supports it and what evidence proves the control works.

Lab 1.1: When the Model Is the Only Control
30 minutes, browser only. A guided first look at a public prompt-injection practice target, with an evidence template and completion rubric.
Lab 1.2: Observe Learned, Probabilistic Behavior
45 minutes, runs locally on synthetic data. Shows why the same input can produce different outputs and what seeds and versions prove.
