DDoS presents a serious threat to the Internet since its inception, where lots of controlled hosts flood the victim site with massive packets. Moreover, in Distributed Reflection DoS (DRDoS), attackers fool innocent servers (reflectors) into flushing packets to the victim. But most of current DRDoS detection mechanisms are associated with specific protocols and cannot be used for unknown protocols. It is found that because of being stimulated by the same attacking flow, the responsive flows from reflectors have inherent relations: the packet rate of one converged responsive flow may have linear relationships with another. Based on this observation, the Rank Correlation based Detection (RCD) algorithm is proposed.
