Toward Scalable Denial of Service Attack Prevention

In this talk, I will discuss recent advances in protecting the global Internet against spoofed distributed denial of service (DDoS) attacks. The new approach is based on distributed route-based packet filtering, a technique that allows networking techniques -- as opposed to crytographic techniques -- to be used to provide a form of authentication on the Internet. I will show that distributed route-based packet filtering is scalable, imparting both proactive and reactive protection, as well as being incrementally deployable.
