Peer-to-Peer (P2P) Simulation for Network Security

Peer-To-Peer (P2P) networks have become a primary propagation mechanism of malicious code through file sharing applications. Many of the modern day malicious codes are being custom designed and deployed to specifically target P2P networks. These codes are tailored to take advantage of the characteristics of P2P protocols and the resulting P2P networks that typically overlay existing networks like the Internet. This research paper discusses an ongoing investigation into a method for increasing P2P networks' resistance to malicious code propagation. The concept is shown through the simulation of P2P networks and the application of mechanisms that influence the topology of the network.
