Spring Security Essentials

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 9. Building a Security Layer for RESTful Web Services

Representational State Transfer (REST) is an architectural style with which other web services can be designed. It serves the resources based on the request from the client. Web service is nothing but a unit of managed code that can be invoked using HTTP requests. We can develop the core functionality of any application and expose the same by deploying it in a server. The exposed web services can be accessed using URIs through HTTP requests from a wide range of client applications. With this method, duplication of business services for different implementations, such as desktop, mobile, and so on, will be avoided.

RESTful web services are quick in responding as there is no strict specification such as SOAP web services. REST requires much less bandwidth and resources, as it is a lightweight design. It is also language- and platform-independent. RESTful web services are applicable for any programming language and platforms. We...
