The Web Application Hacker's Handbook

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.

Approaches to Code Review

You can take a variety of approaches to carrying out a code review to help maximize your effectiveness in discovering security flaws within the time available. Furthermore, you can often integrate your code review with other test approaches to leverage the inherent strengths of each.

Black-Box Versus White-Box Testing

The attack methodology described in previous chapters is often described as a black-box approach to testing. This involves attacking the application from the outside and monitoring its inputs and outputs, with no prior knowledge of its inner workings. In contrast, a white-box approach involves looking inside the application's internals, with full access to design documentation, source code, and other materials.

Performing a white-box code review can be a highly effective way to discover vulnerabilities within an application. With access to source code, it is often possible to quickly locate problems that would be extremely difficult or time...
