Builders vs. Breakers is an interactive debate style talk with heavy audience participation with head to head debates on questions that pit software developers against security professionals (penetration testers). With specific detailed examples, such as how to avoid the problem with a default rails configuration that left github exposed, the goal is to deep dive into both sides of the story for problems that make security so hard in the real world. Questions for debate will be posted/gathered on google docs for preview and participation. Ultimately, this talk aims to be a fun way to raise security awareness with developers, raise developer concerns with security pros, and encourage more active collaboration.
