Research on the comparison of Flood DDoS and Low-rate DDoS

In this paper, two typical types of DDoS, Flood DDoS (FDDoS) and Low-rate DDoS (LDDoS) attacks, are studied on their generation principle, mechanism utilization, behavior, signature, and attack performance. Experiment Results show that: (i) FDDoS sends a large amount of traffic to the victim but it is easy to be detected, (ii) LDDoS organizes a small quantity of traffic to the victim and it is easy to escape from detection. Comparison of FDDoS with LDDoS is helpful to detect and defense against DDoS attacks efficiently.
