Tackling the challenge of distinguishing legitimate traffic from attack would aid in the detection of denial of service (DoS) / distributed DoS (DDoS) attacks. Spoofing of source address would further harden the detection of such attacks. In this paper, we propose a flow based scheme to detect the DoS attacks that adapts itself to the changes trends of the current traffic. The proposed system weeds...
Different from other research work focusing on network-wide traffic, the traffic we focus on for analysis is that of a traffic state viewed from a router??s interior. In this paper, at first, a kind of Port-to-Port traffic in a router is introduced, which we call IF flow. IF flows can amplify the ratio of attack traffic to normal traffic. Then RLS (recursive least square) filter is used to predict...
