E-LDAT: a lightweight system for DDoS flooding attack detection and IP traceback using extended entropy metric

Distributed denial-of-service DDoS attacks cause havoc by exploiting threats to Internet services. In this paper, we propose E-LDAT, a lightweight extended-entropy metric-based system for both DDoS flooding attack detection and IP Internet Protocol traceback. It aims to identify DDoS attacks effectively by measuring the metric difference between legitimate traffic and attack traffic. IP traceback is performed using the metric values for an...
