Research on intrusion and defense of P2P-based worm

P2P worm is virus that propagate rely on P2P network. Worm can achieve the information of the neighbor nodes easily through the routing table of infected nodes. Therefore, the propagation of P2P worm is faster than in other network. P2P worm will cause serious network congestion and revelation of private information. The paper proposes a distributed detection and defense strategy for P2P worm based on hiberarchy, and makes quantitative analysis for the propagation and attack process of the P2P worm. The simulation experiments demonstrate: the strategy has a satisfactory effect on suppressing and eliminating P2P worm.
