Have you ever been asked to "think like a hacker?" Do your eyes glaze over when you have to sit through a security audit of your application? Do you want to avoid having an incident? If any of these apply to you, consider participating in a Capture the Flag (CTF) competition. In this conference talk, John Koerner will explore the basic concepts of a CTF, a bevy of tools that are available to you, and dig into some example flags that have relevance to you as a developer. John will also cover topics such as buffer overflows, SQL injection, and cross site scripting, just to name a few. You'll walk away with the skills needed to participate in your first (or your next) CTF competition and with the knowledge of how this will make your applications more secure.
