Episode 17 — API Basics for Security Analysts: Requests, Authentication, and Common Failures (Task 2)

This episode teaches API basics in security terms so you can evaluate risk, investigate incidents, and answer exam questions that assume modern application architecture. You will define core API request structure, authentication patterns, authorization enforcement, and why “working authentication” does not guarantee safe access. We will cover common failures such as broken object level authorization, weak token handling, insufficient rate limiting, and missing input validation that leads to injection or data exposure. You will also learn how to think about API logs, what fields matter for attribution, and how to troubleshoot suspicious patterns like automated enumeration or privilege boundary bypass. The exam typically rewards analysts who can connect an API symptom to the correct root cause category and recommend a control that prevents recurrence while preserving business function.
