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.

Chapter 17
Attacking Application Architecture

Web application architecture is an important area of security that is frequently overlooked when the security of individual applications is appraised. In commonly used tiered architectures, a failure to segregate different tiers often means that a single defect in one tier can be exploited to fully compromise other tiers and therefore the entire application.

A different range of security threats arises in environments where multiple applications are hosted on the same infrastructure, or even share common components of a wider overarching application. In these situations, defects or malicious code within one application can sometimes be exploited to compromise the entire environment and other applications belonging to different customers. The recent rise of “cloud” computing has increased the exposure of many organizations to attacks of this kind.

This chapter examines a range of different architectural configurations and describes...
