The most basic defense at the network layer is RFC? 2827 [3]. Using input source filtering, ISP refuses to route a packet whose source IP address does not belong to its source subnet further. Input source filtering can effectively prevent SYN flooding attacks disguised as IP. However, this method is useless at present because it is difficult to deploy on a large scale. Moreover, input source filtering cannot resist distributed attacks.
