Spc-Based Approach For Ddos Attack Detection Using X-Mr Control Chart

Distributed denial of service (DDoS) is an evolving critical threat for wireless (Wi-Fi) networks. The malicious nodes' primary purpose is to overload the access point resources by establishing an excessive number of connections or requests until saturation. In this paper, a new detection method based on the Statistical Process Control (SPC) is proposed using an X-MR chart. This method allows detecting DDoS attacks in real-time and does not require any modification of the 802.11 standard or the OpenFlow protocol. It also offers network real-time monitoring, which helps to identify variations due to attacks. A graphical representation of the delay and throughput is used to supervise the network.
