DDoS testbed based on peer-to-peer grid

Distributed Denial of Service (DDoS) attacks and defence against them poses great challenge in network security. Studying of DDoS mitigation strategies, understanding of secure state of a network as well as the testing of defense appliances is the main purpose of our testbed. The testbed is based on a P2P grid-Our Grid environment and aids to run DDoS attacks on existing nodes of P2P grid to use spreading, control, and attack techniques for testing of real network system. We employ the P2P grid environment to carry out as well as to coordinate DDoS attack on the availability of services to simulate real DDoS attack launched indirectly through many compromised computing systems. The paper gives background, design and experimental practice of the testbed.
