A Collaborative Network Security Platform in P2P Networks

Network security problems emerge in an endless stream and cause the inestimable damage. To solve network security problems efficiently, it is not enough to make good protection at nodes or protect networks from outside attacks. Many network security problems should be solved efficiently in collaborative approaches which can integrate various resources over internet to defense network security. In this paper, we have designed and implemented a collaborative network security platform based on P2P system. The nodes participated in the P2P system can publish their designed defensible services against network security problems. Based on the published services, collaborative network applications can be developed easily to solve the network security problems on demand. An experiment against TCP SYN flooding attack is demonstrated by the designed defensible services including packets sniffing, forwarding, filtering, and logging services, which can trace the attack origins and filter malicious traffic efficiently.
