Detection of distributed denial of service (DDoS) attacks over the Internet is crucial for many Internet applications, such as electronic commerce, network games, P2P, etc. Based on anomaly detection information, network route selection, quality of service (QoS) provision, and traffic engineering can be performed to bypass the abnormal areas or to immigrate the attack traffic. To detect the DDoS attacks...
Identifying anomaly detection such as failure and attacks rapidly and accurately over the Internet holds interest of both network operators and researchers. Network behavior analysis (NBA) system is usually disposed over an intranet, passively collects SNMP data or flow data, and uses signature and anomaly mechanisms to identify and analyze interesting network activities, including traffic anomaly...
