With the immense development of computer networks, the network security problems have also developed simultaneously, causing severe damage, thus reducing the efficiency of the networks and also the nodes in the networks. Protection provided at the nodes is not sufficient to completely protect the node from external attacks, hence a collaborative approach, is used to solve the network security problems. This paper explains the implementation of collaborative network security platform based on a Peer-to-Peer (P2P) network. An experiment is demonstrated where-in a peer can download a required file from a central server; these files may contain malicious software that could affect the peer. The services required to deal with the malicious software is provided by another server.
