Spring Security 3.1

Overview of this book

<p>Knowing that experienced hackers are itching to test your skills makes security one of the most difficult and high-pressure 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.<br /><br />"Spring Security 3.1" is an incremental guide that will teach you how to protect your application from malicious users. You will learn how to cleanly integrate Spring Security into your application using the latest technologies and frameworks with the help of detailed examples.<br /><br />This book is centred around a security audit of an insecure application and then modifying the sample to resolve the issues found in the audit.<br /><br />The book starts by integrating a variety of authentication mechanisms. It then demonstrates how to properly restrict access to your application. It concludes with 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.<br /><br />"Spring Security 3.1" will ensure that integrating with Spring Security is seamless from start to finish.</p>

Considerations for a typical ACL deployment


Actually deploying Spring ACL in a true business application tends to be quite involved. We wrap up coverage of Spring ACL with some considerations that arise in most Spring ACL implementation scenarios.

About ACL scalability and performance modelling

For small and medium-sized applications, the addition of ACLs is quite manageable, and while it adds overhead to database storage and runtime performance, the impact is not likely to be significant. However, depending on the granularity with which ACLs and ACEs are modeled, the numbers of database rows in a medium- to large-sized application can be truly staggering, and can task even the most seasoned database administrator.

Let's assume we were to extend ACLs to cover an extended version of the JBCP Calendar application. Let's assume that users can manage accounts, post pictures to events, and administer (add/remove users) from an event. We'll model the data as follows:

  • All users have accounts.

  • 10 percent...
