Advanced API Security: OAuth 2.0 and Beyond

Advanced API Security for Real-World Systems

Advanced API Security: OAuth 2.0 and Beyond takes a practical, standards-driven look at how APIs are protected in modern enterprise systems. Rather than treating security as a single layer added at the end, the book moves through the decisions that shape secure API design from the start: transport security, gateway controls, OAuth 2.0, OpenID Connect, message-level protections, and federated access.

This second edition is especially useful for readers working with APIs that must serve mobile apps, microservices, and identity-aware applications. The chapter structure shows a clear progression from core concepts to implementation-focused topics such as PKCE, device authorization, token binding, JWS, JWE, and API gateway enforcement.

What the Book Covers

• API security design and threat-aware thinking
• TLS and mutual TLS for transport protection
• OAuth 2.0 grant types and token handling
• OpenID Connect for identity-aware API access
• JSON Web Signature and JSON Web Encryption
• API gateway patterns for edge security
• Mobile and federated access scenarios

Who It Suits

This title is well matched to security architects, developers, and engineers who need a structured reference for protecting APIs in enterprise environments. It is also a strong fit for readers who want to understand how authentication, authorization, and token-based security fit together in practice.

A Focused Reference for API Security Work

If you are looking for a book that connects the “why” of API protection with the “how” of today’s common security standards, this is a sharp, highly relevant addition to a technical library.
