" Tracking information flow in web applications"

 

Abstract:

This talk discusses a principled approach to web application security through tracking information flow in web applications. Although the agile nature of developments in web application technology makes web application security much of a moving target, we show that there are some fundamental challenges and tradeoffs that determine possibilities and limitations of automatically securing web applications. We address challenges related to mutual distrust on the policy side (as in web mashups) and tracking information flow in dynamic web programming languages (such as JavaScript) to provide a foundation for practical web  application security.
