Abstract

Distributed denial of service (DDoS) attack is one of the major threats to the current Internet. The IP Flow feature value (FFV) algorithm is proposed based on the essential features of DDoS attacks, such as the abrupt traffic change, flow dissymmetry, distributed source IP addresses and concentrated target IP addresses. Using linear prediction technique, a simple and efficient ARMA prediction model is established for normal network flow. Then a DDoS attack detection scheme based on anomaly detection techniques and linear prediction model (DDAP) is designed. Furthermore, an alert evaluation mechanism is developed to reduce the false positives due to prediction error and flow noise. The experiment results demonstrate that DDAP is an efficient DDoS attacks detection scheme with more accuracy and lower false alarm rate.
