Testing API security and authentication: OWASP API Top 10, OAuth, JWT, fuzzing and rate limits.
API security testing guides: OWASP API Top 10 test cases, OAuth and JWT testing, fuzz testing, rate limiting, a security checklist and tools compared.
How JWT signing keys end up in test files, what the blast radius looks like, and the enterprise controls that prevent it. Pre-commit detection, CI scanning, vault integration, and key rotation patterns that hold up to audit.
How to design OAuth 2.0 negative test suites that catch real-world auth vulnerabilities across enterprise IdPs. PKCE mismatch, token reuse, scope escalation, and redirect-URI tampering with worked examples for Okta, Azure AD / Entra ID, and Ping Identity.
How enterprise security teams operationalize the OWASP API Security Top 10 (2023) as concrete SDL controls — not just a test checklist. Mitigation patterns, evidence per control, and the program structure that survives procurement and audit review.
Learn how to test API authentication and authorization comprehensively. Covers OAuth, JWT, RBAC, BOLA, BFLA, and automated auth testing in CI/CD pipelines.
The OWASP API Top 10 (2023) mapped to enterprise mitigations. BOLA, authentication failures, broken object property authorization, and the rest — with concrete test patterns and SDL controls for each.
How to test API rate limiting and throttling: threshold, header, and window-reset test cases with k6 and Python burst scripts, plus multi-tenant per-client isolation and audit-ready validation patterns.
What API fuzz testing is, how mutation, generation and schema-based fuzzing differ, the main tools (Schemathesis, RESTler, ZAP, ffuf), a worked Schemathesis example against an OpenAPI spec, how to triage findings and how to run fuzzing in CI.
Enterprise-focused buyer's guide to API security testing tools for 2026. Compare OWASP ZAP, Burp Suite, 42Crunch, StackHawk, and more across SDL fit, on-prem deployment, audit evidence, and AI-policy alignment.
Master OAuth API testing with best practices for authorization code, client credentials, and token flows. Complete 2026 guide for secure OAuth implementation.
A 76-item API security testing checklist mapped to the OWASP API Security Top 10 (2023), with test ideas per risk, JWT and OAuth checks, rate limiting, data exposure and logging, and a downloadable CSV you can import into your test tracker.
The MCP threat model and the test cases that cover it — tool poisoning, confused deputy, token passthrough, session hijacking, DNS rebinding and excessive agency, with runnable assertions for each.
JWT authentication testing: the full attack-matrix test cases (signature, algorithm confusion, none-alg, claims, expiration), code examples with jose, and a tools comparison — with worked examples for Okta, Azure AD, and Ping for enterprise IdP flows.
