Chapter 21
A Web Application Hacker's Methodology

This chapter contains a detailed step-by-step methodology you can follow when attacking a web application. It covers all the categories of vulnerabilities and attack techniques described in this book. Following all the steps in this methodology will not guarantee that you discover all the vulnerabilities within a given application. However, it will provide you with a good level of assurance that you have probed all the necessary regions of the application's attack surface and have found as many issues as possible given the resources available to you.

Figure 21.1 illustrates the main areas of work that this methodology describes. We will drill down into this diagram and illustrate the subdivision of tasks that each area involves. The numbers in the diagrams correspond to the hierarchical numbered list used in the methodology, so you can easily jump to the actions involved in a specific area.
