Recently, the trend in network security is the growing number of malicious attacks which resulted in abnormal network data traffic as well as direct damaging of the system. Specifically, Distributed denial of service (DDoS) attacks use bandwidth flooding of intended victims where the bandwidth consumption of these attacks influences the entire network performance. These attacks aggregate at a target's access router which implies that attacks are most readily detectable at access routers. The accuracy of detection dictates data traffic monitoring but performing such monitoring for the numerous devices in a distributed sensor network presents serious scalability issues. This paper describes the design space for distributed sensor network DDoS detection and propose a multiphase distributed approach that detect DDoS attacks to provide reliability and scalability.
