It's as certain as death and taxes: crackers will mercilessly attack your web sites, applications, and services. If you're vulnerable, you'd better discover these attacks before the black hats do. "How to Break Web Software" is a hands-on guide to security-testing web-based software.

In this book, the authors address every category of Web software exploit: attacks on clients, servers, state, user inputs, and more. They describe attack tools and techniques as well as dozens of crucial, widely exploited flaws in Web architecture and coding. The authors reveal where to look for potential threats and attack vectors, how to rigorously test for each of them, and how to mitigate the problems you find. Coverage includes

• Client vulnerabilities, including attacks on client-side validation
  
• State-based attacks: hidden fields, CGI parameters, cookie poisoning, URL jumping, and session hijacking
  
• Attacks on user-supplied inputs: cross-site scripting, SQL injection, and directory traversal
  
• Language- and technology-based attacks: buffer overflows, canonicalization, and NULL string attacks
  
• Server attacks: SQL Injection with stored procedures, command injection, and server fingerprinting
  Cryptography, privacy, and attacks on Web services

A companion CD contains full source code for one testing tool to modify and extend, free Web security testing tools, and complete code from a flawed Web site designed to provide hands-on practice in identifying security holes.
