Overview of this book

Implementing authentication and authorization for applications can be a daunting experience, often leaving them exposed to security vulnerabilities. Keycloak is an open-source solution for identity management and access management for modern applications, which can make a world of difference if you learn how to use it. Keycloak, helping you get started with using it and securing your applications. Complete with hands-on tutorials, best practices, and self-assessment questions, this easy-to-follow guide will show you how to secure a sample application and then move on to securing different application types. As you progress, you will understand how to configure and manage Keycloak as well as how to leverage some of its more advanced capabilities. Finally, you'll gain insights into securely using Keycloak in production. By the end of this book, you will have learned how to install and manage Keycloak as well as how to secure new and existing applications.

In this chapter, you experienced first-hand the interactions in an OIDC authentication flow. You learned how the application prepares an authentication request and then redirects the user-agent to the Keycloak authorization endpoint for authentication. Then you learned how the application obtains an authorization code, which it exchanges for an ID token. By inspecting the ID token, you then learned how an application can find out information about the authenticated users. You also learned how to leverage client scopes and protocol mappers in Keycloak to add additional information about users. Finally, you learned how to deal with not only single sign-on, but also single sign-out.

You should now have a basic understanding of OpenID Connect and how it can be used to secure your own applications. We will build on this knowledge later in the book to get you ready to start securing all your applications with Keycloak.

In the next chapter, you will get a deeper understanding...
