Webapps In Name Only Thomas Ptacek, Matasano Security

Where modern network architecture meets legacy application design, we get "The Port 80 Problem": vendors wrapping every conceivable network protocol in a series of POSTs and calling them "safe". These "Webapps In Name Only" are a nightmare for application security specialists.

In this talk, we'll discuss, with case studies, how tools from protocol reverse engineering can be brought to bear on web application security, covering the following areas:

- Locating and Decompiling Java and .NET Code - Structure and Interpretation of Binary Protocols in HTTP - Protocol Debugging Tools - Web App Crypto Tricks

Token-less strong authentication for web applications: A Security Review Cory Scott, ABN AMRO

A short presentation on the threat models and attack vectors for token-less schemes used to reduce the risk of password-only authentication, but yet do not implement "true" two-factor technologies for logistical costs or user acceptance reasons. We'll go over how device fingerprinting and IP geo-location work and discuss the pros and cons of the solutions.
