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.

Access control lists in Spring Security

Spring Security supports ACL-driven authorization checks against access to individual domain objects by individual users of the secured system. Much as in the OS filesystem example, it is possible to use the Spring Security ACL components to build logical tree structures of both business objects and groups or principals. The intersection of permissions (inherited or explicit) on both the requestor and the requestee is used to determine allowed access.

It's quite common for users approaching the ACL capability of Spring Security to be overwhelmed by its complexity, combined with a relative dearth of documentation and examples. This is compounded by the fact that setting up the ACL infrastructure can be quite complicated, with many interdependencies and reliance on bean-based configuration mechanisms, which are quite unlike much of the...
