Denial of service (DoS) attacks are a large and increasing threat to the Internet community. In this paper, we propose using a distributed approach to DoS defense. Our architecture leverages the properties of a wide-area overlay network to isolate clusters of attackers while denying access to a minimal amount of legitimate users. This is done by collaborating with other members of a structured peer-to-peer network, which is inherently collaborative. Our results show that our approach is effective at both detection and suppression of a DoS attack.
