Udemy – Master OAuth 2.0: A Practical Guide to API Security 2024-12

Master OAuth 2.0: A Practical Guide to API Security. This course is a comprehensive resource for designing, implementing, and managing secure API infrastructures. Suitable for both experienced developers and beginners, this course provides a comprehensive, practical approach to understanding OAuth 2.0, OpenID Connect, token-based authentication, and more. Throughout the course, you will learn about access tokens, refresh tokens, JWT, SAML, and other advanced security protocols to effectively secure your modern applications and services.

What you will learn:

• OAuth 2.0 token types and formats: Explore access tokens, refresh tokens, JWTs, and opaque tokens to secure modern APIs.
• Understand token validation methods: Discover when to use local validation or introspection for secure and efficient token verification.
• Choosing the right type of OAuth client: Learn when to use public or private clients.
• Defining and Structuring OAuth Scopes: Learn to name and structure OAuth scopes to effectively and precisely control access to your API.
• OIDC Basics: Understand how OpenID Connect extends OAuth for user authentication and unified sign-in.
• Master user-initiated flows: Learn Implicit, Authorization Code, and PKCE flows for secure user authentication.
• Review flow challenges: Analyze vulnerabilities with real-world attack scenarios and effectively address them.
• 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.
• Implementing Machine-to-Machine Flows: Learn Client Credentials Flow for secure communication of backend services.
• Understanding ROPC and Device Code Flows: Discover flows such as Resource Owner Password Credentials and Device Code for resource owners and devices with restricted input.
• Master advanced client authentication methods: Use JWT, SAML assertions, and X.509 mTLS for strong API security.
• Learn the basics of mTLS X.509: Build a foundational knowledge of mutual TLS, X.509 certificates, and public key infrastructure (PKI).
• Securing OAuth 2.0 access tokens: Protect your tokens with advanced FAPI-compliant mechanisms such as mutual TLS and Demonstration of Proof-of-Possession (DPoP).
• Integrate external identity providers: Connect with partners, JWT providers, and external systems for scalable identity solutions.
• Connect with legacy systems and SAML: Integrate with legacy infrastructure and SAML for staged migrations.
• Simulate real-world scenarios: Analyze attack scenarios and examine the architectures of different projects.
• Informed decision making: Use decision trees to select the best OAuth flows and mechanisms for secure architectures.

This course is suitable for people who:

• Software Engineers and Developers: Whether you’re a backend, frontend, or full-stack developer, this course will give you the practical skills to implement OAuth 2.0 in your projects.
• Solution Architects and Technical Leads: Learn how to design and integrate secure application architectures using OAuth 2.0 for various project scenarios and needs.
• Security professionals: Understand advanced client authentication methods and access token security mechanisms to increase API protection and align with zero trust principles.
• IT professionals migrating legacy systems: Discover how to use OAuth 2.0 for staged migrations and integrate legacy systems with modern security protocols.
• People working with external identity providers: Gain insight into integrating systems like SAML and JWT providers, especially in compliance-driven or partner-integrated environments.
• This course is ideal for anyone involved in designing, implementing, or managing secure application architectures and API security strategies. Whether you’re a beginner or a pro, this course will help you confidently apply OAuth 2.0 in real-world scenarios.
