[[Introduction]]\n[[People]]\n[[Publications]]

This project focuses on distributed denial-of-service (~DDoS) attacks on the Internet. ~DDoS is a serious problem that has not been solved yet and is still an active area of research. In a nutshell, ~DDoS attacks target the availability of services, infrastructure and hosts on the Internet and prevent them from performing their legitimate functionality. ~DDoS attacks can be classified into one of the following categories:\n# Resource Exhaustion (Bandwidth, CPU, Memory ...)\n# Vulnerability Attacks\n# Protocol Attacks\n\nIn this project we are developing techniques and mechanisms to combat resource exhaustion attacks that target the bandwidth of certain links by flooding them with excessive traffic. As a first step we have mapped this kind of attacks to a resource optimization problem and provided analysis of its effect and quantified the effectiveness of filtering mechanisms to mitigate such attacks. We are now working on developing mechanisms to contain such flooding attacks and minimize their effect on saturating Internet links and preventing legitimate traffic from reaching its destination.
