Keycloak - Identity and Access Management for Modern Applications

By: Stian Thorgersen, Pedro Igor Silva

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 learned about the different strategies you can choose from to authorize access to protected resources in your applications. By leveraging token-based authorization, applications should be able to introspect tokens – either locally or through the introspection endpoint – and use their claims to support different access control mechanisms such as RBAC, GBAC, and ABAC, or use the scopes granted by users to the client application acting on their behalf. You also learned that Keycloak can be used as a centralized authorization service to decouple authorization from applications, where access decisions are taken by Keycloak based on the resources and policies managed through the server.

In the next chapter, we are going to look at the main steps for running Keycloak in production.
