Peer 2 Peer networking has become a promising technology and has achieved popularity as a mechanism for users providing them a scalable and fault- tolerant mechanism without retaining a large amount of routing database. This rapid growth of Peer 2 Peer networks makes them an attractive target to the creators of viruses and other security threats. Similarly, the high risks involved in Peer 2 Peer systems have focused attention on various security issues like Confidentiality, Authentication, Interoperability, Vulnerability, and Integrity in the Peer 2 Peer network environment. In this paper a virus model is presented based on an epimedological modeling that predicts how a virus propagates in a P2P network as well as address issues related to virus propagation in a P2P network. The paper includes evaluation of virus propagation, representation and implementation of virus mathematical model exclusively Swen virus in Gnutella network and analyzing its performance, and finally the simulation results obtained from simulator runs with the Gnutella protocol are presented with different analysis extracted on the basis of obtained simulation results. |
