My Research
I
did my Masters research on overlay networks with the Tapestry branch of the
Oceanstore group at UC Berkeley. My
research centered on Denial of Service (DoS) attacks in Peer-to-Peer (P2P)
overlay networks. My approach involves
leveraging the properties of P2P overlay networks, and detecting and defending
against DoS attacks in a distributed way.
Abstract:
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 such our approach is
effective at both detection and suppression of a DoS attack.
