Distributed Denial of Service (DDoS) attacks is very recent and popular devastating attack in the field of cyber society. Flooding DDoS attacks produce adverse effects for critical infrastructure availability, integrity and confidentiality. Current defense approaches cannot efficiently detect and filter out the attack traffic in real time. Online analysis of real time attack traffic and their impact and degradation of host and network based performance metrics becomes very essential. So, online measurement of these network performance metrics itself acts as an intrusion detection system.
