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.

This book has focused on the practical techniques you can use to attack web applications. Although you can carry out some of these tasks using only a browser, to perform an effective and comprehensive attack of an application, you need some tools.

The most important and indispensable tool in your arsenal is the intercepting proxy, which enables you to view and modify all traffic passing in both directions between browser and server. Today's proxies are supplemented with a wealth of other integrated tools that can help automate many of the tasks you will need to perform. In addition to one of these tool suites, you need to use one or more browser extensions that enable you to continue working in situations where a proxy cannot be used.

The other main type of tool you may employ is a standalone web application scanner. These tools can be effective at quickly discovering a range of common vulnerabilities, and they can also help you map and analyze an application's functionality...
