OAuth 2.0 with practical flows, implementations, real-world use cases, and decision-making for robust API architectures

What you’ll learn

Learn OAuth 2.0 Token Types and Formats: Explore access tokens, refresh tokens, JWT, and opaque tokens to secure modern APIs.

Understand Token Validation Methods: Discover when to use local validation or introspection for efficient and secure token verification.

Choose the Right OAuth Client Type: Learn when to use public or confidential clients.

Define and Structure OAuth Scopes: Learn to name and structure OAuth scopes for effective, granular API access control.

Gain Basics of OIDC: Understand how OpenID Connect extends OAuth for user authentication and single sign-on.

Master User-Initiated Flows: Learn Implicit, Authorization Code, and PKCE flows for secure user authentication.

Explore Flow Challenges: Analyze vulnerabilities with real-world hacker scenarios and address them effectively.

Choose the Best Flow: Use decision trees to identify the ideal OAuth flow for your project needs.

Discover Advanced Flow Mechanisms: Learn JWT Secured Authorization Request (JAR), JWE, and Pushed Authorization Request (PAR) to enhance OAuth 2.0 security.

Implement Machine-to-Machine Flows: Learn the Client Credentials Flow for secure backend service communication.

Understand ROPC and Device Code Flows: Discover flows like Resource Owner Password Credentials and Device Code for resource owner and devices with limited input

Master Advanced Advanced Client Authentication Methods: Use JWT, SAML assertions, and X.509 mTLS for robust API security.

Learn mTLS X.509 Basics: Build foundational knowledge of mutual TLS, X.509 certificates, and Public Key Infrastructure (PKI).

Secure OAuth 2.0 Access Tokens: Protect your tokens with advanced FAPI-compliant mechanisms like mutual TLS and Demonstration of Proof-of-Possession (DPoP).

Connect with Legacy and SAML Systems: Integrate with legacy infrastructures and SAML for phased migrations.

Simulate Real-World Scenarios: Analyze attacker scenarios and explore diverse project architectures.

Make Informed Decisions: Use decision trees to select the best OAuth flows and mechanisms for secure architectures.

Requirements

A general understanding of HTTP concepts, such as methods (GET, POST), headers, and status codes.

This course is designed for both beginners and advanced learners, so no prior knowledge of OAuth 2.0 is required.
