The TCP/IP protocols consist of a four layer model, also known as the DARPA model. The four layer of the DARPA model are application layer, transport layer, internet layer and network interface layer. In this paper, the authors represent network attacks generally adopt computer networks as transportation media to convey the intrusion or even attack the communication system itself. They will put their focus mainly on the network attacks happened around the TCP/IP (Transmission Control Protocol/Internet Protocol) protocol suite, which are the most widely used communication protocol and the de facto standard among the Internet society.
