- This course is designed for both beginners and advanced learners, so no prior knowledge of OAuth 2.0 is required.
Description
Master OAuth 2.0: A Practical Guide to API Security is your one-stop resource for designing, implementing, and managing secure API infrastructures. Whether you’re a seasoned developer or just starting out, this course offers a comprehensive, hands-on approach to understanding OAuth 2.0, OpenID Connect, token-based authentication, and more. Throughout the lessons, you’ll explore access tokens, refresh tokens, JWTs, SAML, and other cutting-edge security protocols to effectively secure your modern applications and services.
You’ll learn when and how to apply local token validation versus token introspection, how to choose between public and confidential clients, and how to define scalable OAuth scopes that fit your project’s exact requirements. With in-depth coverage of user-initiated flows—such as the Authorization Code Flow, Proof Key for Code Exchange (PKCE), and Implicit Flow—you’ll gain a firm grasp on configuring these flows in real-world scenarios. We’ll also tackle advanced topics like mutual TLS (mTLS), advanced client authentication methods (including JWT and SAML assertions), FAPI-compliant token security mechanisms such as Demonstration of Proof of Possession (DPoP), and even PKI (Public Key Infrastructure) basics to support secure certificate-based solutions.
For machine-to-machine communication, you’ll master the Client Credentials Flow and learn how to integrate external identity providers or legacy systems without compromising performance or security.
You’ll walk through hands-on cURL simulations, attacker scenarios, and decision trees that make it easy to map OAuth best practices to your specific project environment. By understanding each chapter’s detailed agenda and applying core concepts step by step, you’ll build robust API security strategies that scale—whether you’re migrating a legacy system or launching a new zero-trust architecture.
Don’t let confusion about flows, configurations, or integrations hold you back. Enroll now and take the guesswork out of OAuth 2.0!
