I recently presented at StartPad, a local co-working space in Seattle, on web application security. It was a great talk, mostly due to the great discussion generated by the crowd. StartPad was nice enough to record the presentation and you can find that, as well as my slides, below. Topics covered include: web application security, including the basics of SQL Injection and Cross-Site Scripting, Data Breach laws and even some discussion on PCI compliance. I also did some demos including a SQL Injectable Ruby on Rails app.
Enjoy!
