Detection of Denial of Service attacks on Mobile Internet Protocol Nodes
DDoS (Distributed Denial of Service) attacks are the most common network attacks that had caused a serious economic loss so it is has to been stopped as early as possible to protect network damage. Earlier solutions for this problem are based on port-hopping between pairs of processors which are synchronous or exchange acknowledgments. The authors' main aim is to detect the malicious connection from the normal ones by using decision tree analysis and protect the server from attackers. In this paper, they understand the packet flow ratio from normal connections and then from abnormal situation if the ratio of the packet flow differs from the normal ratio they distinguish normal and malicious connections.
