Appendix A: Tools of the Trade
Whenever you work on a project, such as building a house or demolishing it, having the right tools for the job is essential. This concept is no different when testing an application, especially testing for security vulnerabilities. Several tools are available to make your job of looking for security flaws easier. Throughout the book, we mention several tools and even discuss some of their weaknesses.
This appendix enumerates some of the tools that we believe are helpful when hunting security bugs . The tools are organized into categories of interest. Remember, tools are always evolving. Sometimes today s best tool is replaced by a better tool tomorrow. Seek out newer tools if you find the ones you are using don t meet your expectations, and keep current as new tools become available that do a better job in helping you test.
