Spring Security Essentials

By: Nanda Nachimuthu

Overview of this book

<p>Spring Security is a framework that focuses on providing both authentication and authorization to Java applications. Like all Spring projects, the real power of Spring Security is how easily it can be extended to meet custom requirements. The popularity of the Spring framework is increasing and the security package of Spring addresses vast mechanisms of Security in a rich way. Due to an increasing number of applications for various business needs, the integration of multiple applications is becoming inevitable. The standard security procedures available across multiple implementations in Spring will protect vulnerable applications that are open to larger public and private audiences.</p> <p>Spring Security Essentials focuses on the need to master the security layer, which is an area not often explored by a Spring developer.</p> <p>At the beginning, we’ll introduce various industry standard security mechanisms and the practical ways to integrate with them. We will also teach you about some up-to-date use cases such as building a security layer for RESTful web services and applications.</p> <p>The IDEs used and security servers involved are briefly explained, including the steps to install them. Many sample projects are also provided to help you practice your newly developed skills. Step-by-step instructions will help you master the security layer integration with the Server, then implement the experience gained from this book in your own real-time application.</p>

Chapter 5. Spring Security with ACL

Access control list (ACL) is used to map the permissions of the objects against the users of an application. ACL will have the access grants for users and system process in order to access and perform operations on particular objects. Typically, ACL stores the operation against an object by a user. In Java programming, you can assume an entry in ACL, such as Admin: Create or User: Read, for a given screen or entity that would give permission to the Admin to create an entity and the User to read the same. The implementation of ACL using SQL and File System may also vary for different technologies.

Advanced SQL-based ACL implementations follow role-based access control (RBAC) models. The RBAC model is widely used in security applications that have complex security requirements, such as role-based data segregation. In SQL implementation, ACLs are used to manage groups, subgroups, and hierarchy of groups. The flexibility, in terms of creating and managing...
