Hands-On Spring Security 5 for Reactive Applications

By: Tomcy John

Overview of this book

Spring Security enables developers to seamlessly integrate authorization, authentication, and a range of security features for complex enterprise applications. This book provides a hands-on approach to developing reactive applications using Spring and will help you get up and running in no time. Complete with step-by-step explanations, practical examples, and self-assessment questions, the book begins by explaining the essential concepts of reactive programming, Spring Framework, and Spring Security. You’ll then learn about a variety of authentication mechanisms and how to integrate them easily with a Spring MVC application. You’ll also understand how to achieve authorization in a Spring WebFlux application using Spring Security. Furthermore, the book will take you through the configuration required to implement OAuth2 for securing REST APIs, and guide you in integrating security in microservices and serverless applications. Finally, you’ll be able to augment add-ons that will enhance any Spring Security module. By the end of the book, you’ll be equipped to integrate Spring Security into your Java enterprise applications proficiently.

Other Spring Security capabilities

Spring Security has a number of capabilities apart from core security features, authentication and authorization. Some of the most important ones are listed here. In Chapter 7Spring Security Add-Ons, we will go through each of these in more detail using hands-on coding. We will build on the example that we have created in this chapter and explain each of these very important Spring Security capabilities:

  • Remember-me authentication: This is also known as persistent-login, and it allows websites to remember a user's identity in between multiple sessions. Spring Security provides a couple of implementations (hashed-token-based and persistent-token-based) that make this easy.
  • Cross Site Request Forgery (CSRF): This is a very common security exploit employed by hackers to do unethical operations, whereby unauthorized commands are sent on behalf of the user. Spring Security allows us to fix this exploit easily with configurations.
  • Cross-Origin Resource Sharing...
