Overview of this book

Knowing that experienced hackers are itching to test your skills makes security one of the most difficult and high-pressured concerns of creating an application. The complexity of properly securing an application is compounded when you must also integrate this factor with existing code, new technologies, and other frameworks. Use this book to easily secure your Java application with the tried and trusted Spring Security framework, a powerful and highly customizable authentication and access-control framework. The book starts by integrating a variety of authentication mechanisms. It then demonstrates how to properly restrict access to your application. It also covers tips on integrating with some of the more popular web frameworks. An example of how Spring Security defends against session fixation, moves into concurrency control, and how you can utilize session management for administrative functions is also included. It concludes with advanced security scenarios for RESTful webservices and microservices, detailing the issues surrounding stateless authentication, and demonstrates a concise, step-by-step approach to solving those issues. And, by the end of the book, readers can rest assured that integrating version 4.2 of Spring Security will be a seamless endeavor from start to finish.

Custom Authentication

In Chapter 2, Getting Started with Spring Security, we demonstrated how to use an in-memory datastore to authenticate the user. In this chapter, we'll explore how to solve some common, real-world problems by extending Spring Security's authentication support to use our existing set of APIs. Through this exploration, we'll get an understanding of each of the building blocks that Spring Security uses in order to authenticate users.

During the course of this chapter, we will cover the following topics:

  • Leverage Spring Security’s annotations and Java-based configuration
  • Discovering how to obtain the details of the currently logged-in user
  • Adding the ability to log in after creating a new account
  • Learning the simplest method for indicating to Spring Security, that a user is authenticated
  • Creating custom UserDetailsService and AuthenticationProvider...
