Abstract
To showcase the expressive power of our framework, I apply it to study network Denial of Service (DoS) attacks, and model resilience to such attacks as a survivability property. I show how we can systematically analyze the relative impact of different anti-DoS strategies by changing policies and mechanisms during an attack. Using our automated verification methodology, we formally prove for the first time whether strategies such as selective filtering, strong-authentication, and client-puzzles reduce the vulnerability of an example network to DoS attacks.
