Nowadays, the security of P2P networks is alarming ascribing to worms which propagate by exploiting common vulnerabilities in P2P software. Taking account of the topology of P2P networks and the behavior of worms, this paper models the propagation of active worms in unstructured P2P networks. Simulations indicate that propagation of worms in P2P networks is much faster than that in un-P2P networks. This paper highlights the analysis of the impact of worm propagation brought by attack and defense strategy changes from the angle of network topology. Finally we put forward a suggestion of worm defense in P2P networks.
