Solving Identity Management in Modern Applications: Demystifying OAuth 2, OpenID Connect, and SAML 2, 2nd Edition

Know how to design and use identity management to protect your application and the data it manages.

At a time when security breaches result in increasingly onerous penalties, it is paramount that application developers and owners understand identity management and the value it provides when building applications. This book takes you from account provisioning to authentication to authorization, and covers troubleshooting and common problems to avoid. The authors include predictions about why this will be even more important in the future. Application best practices with coding samples are provided.

Solving Identity and Access Management in Modern Applications gives you what you need to design identity and access management for your applications and to describe it to stakeholders with confidence. You will be able to explain account creation, session and access management, account termination, and more.

This expanded edition has been revised to provide an overview of the new version of OAuth (2.1)―the primary changes in this version, including features that were removed from 2.1 that were in 2.0 and why they were removed. The discussion of the book's accompanying sample application has been revised to cover in more depth the approach for developing the application (also revised). A new section has been added on the OAuth 2.0 Device Authorization Grant (RFC 8628) specification, which is useful for devices with limited UI capability. Minor additions include the topics of identity proofing, the need to capture and organize consent information, the impact of tracking prevention technology on certain identity protocols, and the availability of additional options for authorization requests such as OAuth 2.0 Rich Authorization Requests and JWT-Secured Authorization Requests (RFC 9101).

About the Author

Yvonne Wilson is co-founder and Chief Strategy Officer for XploitDefense. She has had many roles in the software industry related to security and identity management as a security and identity architect; enterprise architect; director of developer success working with identity customers; sr. director of security governance, risk, and compliance (GRC); Chief Strategy Officer; and founder of cloud identity services. Yvonne was responsible for IT security strategy and architecture at Sun Microsystems, founded and designed the identity management services offered through Oracle Managed Cloud Services, created a GRC team at Auth0 and founded a world-wide developer success team for Auth0, working with customers and overseeing the creation of an identity management training program for customer-facing support and professional services engineers. Yvonne is currently Chief Strategy Officer at XploitDefense.

In working with business teams at Sun, designing and deploying identity systems for customers at Oracle, and while founding a developer success team at Auth0, Yvonne had the opportunity of working with many customers, from small startups to large enterprises. Her experience spans the implementation of SSO, identity federation, directory services, adaptive knowledge-based authentication, and identity provisioning as well as multilevel authentication systems with certificate-based authentication. She has worked with OIDC, SAML 2.0, WS-Fed, OAuth2.0/2.1, and OpenID. From this depth of experience, Yvonne realized the growing need for a basic overview of identity management concepts that is understandable to business application owners as well as architects and developers.

Abhishek Hingnikar is at Okta, the identity provider for the internet. He has several years of experience designing and demonstrating Identity Management solutions to customers using Auth0 using OAuth 2.0/2.1, OpenID Connect and SAML 2.0. His current focus areas involve Consumer IoT, Device Based Identity and designing solutions that explore web based identity in peripheral domains.
