This document discusses common ways that web application security fails and provides examples. It begins with an agenda that covers how to build secure software, examples of real security failures, and a demonstration of security testing. The document then discusses best practices for secure design and implementation, including input validation, as well as examples of real-world attacks like SQL injection, XSS, and logic attacks. It concludes by providing further online resources for topics like the OWASP Top 10 vulnerabilities and security scanning tools.
