ABSTRACT
When
service system is under DDoS attacks, it is important to detect anomaly
signature at starting time of attack
for timely applying prevention solutions. However, early DDoS detection is
difficult task because the velocity of DDoS attacks is very high. This paper
proposes a DDoS attack detection method by modeling service system as M/G/R PS
queue and calculating monitoring parameters based on the model in odder to early
detect symptom of DDoS attacks. The proposed method is validated by
experimental system and it gives good results.
