Detecting Bandwidth DDoS Attack with Control Charts

The distributed denial of service, DDoS, is an internet-wide threat and can be identified in the initial phase through the anomalous behavior of the network traffic. We present a control chart theory approach for the problem of detection this kind of attack, it is designed for non-normal process and is based on the evaluation of estimators that have a minimal variance estimation process position and scattering, whatever the data distribution. We proposed an algorithm to identify the DDoS attacks analyzing these estimators behavior.
