This course delivers 600 carefully-crafted, scenario-based multiple-choice questions covering every major domain of API security, from authentication through incident response.

Organized into six 100-question practice tests, you'll work through:

• Test 1: API Authentication Fundamentals — API keys vs. bearer tokens, OAuth grant types, PKCE, JWT verification, mTLS, and credential lifecycle discipline

• Test 2: Authorization & Access Control — BOLA, BFLA, RBAC vs. ABAC, Mass Assignment, delegated consent, and break-glass access

• Test 3: Injection & OWASP API Top 10 — SQL/NoSQL/command injection, XXE, SSRF, insecure deserialization, and path traversal

• Test 4: Rate Limiting & Abuse Prevention — token buckets, sliding windows, distributed rate limiting, and bot/anomaly detection

• Test 5: Gateway, Encryption & Transport Security — TLS/cipher hardening, certificate pinning, HSTS, WAF layering, and service-mesh mTLS

• Test 6: Testing, Monitoring & Incident Response — fuzzing, penetration testing, SIEM integration, behavioral baselining, and API-specific incident playbooks

Every question comes with a detailed explanation for all four options — not just the correct one — so you understand exactly why an answer is right and why the alternatives fall short. Questions are deliberately written to connect concepts across tests and reinforce genuine, applied reasoning rather than rote memorization, the kind of judgment real API security work actually demands.

This course is ideal for API-security exam preparation, self-assessment, and reinforcing real-world development or AppSec experience. Whether you're a backend developer securing your first production API or a security engineer auditing a mature one, these practice tests are built to help you think like an API security practitioner — not just recall a vulnerability acronym.
