No More Signatures: Defending Web Applications from 0-Day Attacks with ModProfiler Using Traffic Profiling

Web application security is a big problem, yet there is never enough time to dedicate to solving the issue or, at least, making it smaller. To help with this, we embarked on a project that would enable you to tighten the security of your web applications with little effort. The project, called ModProfiler, aims to provide best-possible protection for web applications by analysing web application traffic passing by. This new open source tool builds on the success of ModSecurity (also open source), which is generally considered to be the most widely deployed web application firewall.

The premise is simple: ModProfiler works by observing what's valid and what's not, resulting with a tight application shield designed around the positive security model concept. The process of shield construction is not as simple, but the complexity is hidden away. This talk, presented by Ivan Ristic, the author of the tool, will give you an insight into the technology behind the scenes, and enable you to get the most out of it.
