By: Dafydd Stuttard, Marcus Pinto

Overview of this book

Web applications are the front door to most organizations, exposing them to attacks that may disclose personal information, execute fraudulent transactions, or compromise ordinary users. This practical book has been completely updated and revised to discuss the latest step-by-step techniques for attacking and defending the range of ever-evolving web applications. Youíll explore the various new technologies employed in web applications that have appeared since the first edition and review the new attack techniques that have been developed, particularly in relation to the client side. The book starts with the current state of web application security and the trends that indicate how it is likely to evolve soon. Youíll examine the core security problem affecting web applications and the defence mechanisms that applications implement to address this problem, and youíll also explore the key technologies used in todayís web application. Next, youíll carry out tasks for breaking into web applications and for executing a comprehensive attack. As you progress, youíll learn to find vulnerabilities in an application's source code and review the tools that can help when you hack web applications. Youíll also study a detailed methodology for performing a comprehensive and deep attack against a specific target. By the end of this book, youíll be able to discover security flaws in web applications and how to deal with them.

Tools for Code Browsing

The methodology we have described for performing a code review essentially involves reading the source code and searching for patterns indicating the capture of user input and the use of potentially dangerous APIs. To carry out a code review effectively, it is preferable to use an intelligent tool to browse the codebase. You need a tool that understands the code constructs in a particular language, provides contextual information about specific APIs and expressions, and facilitates your navigation.

In many languages, you can use one of the available development studios, such as Visual Studio, NetBeans, or Eclipse. In addition, various generic code-browsing tools support numerous languages and are optimized for viewing of code rather than development. The authors' preferred tool is Source Insight, shown in Figure 19.1. It supports easy browsing of the source tree, a versatile search function, a preview pane to display contextual information about any selected...
