Detection of DDoS attacks and flash events using information theory metrics–An empirical investigation

A Distributed Denial of Service (DDoS) attack is an austere menace to extensively used Internet-based services. The in-time detection of DDoS attacks poses a tough challenge to network security. Revealing a low-rate DDoS (LR-DDoS) attack is comparatively more difficult in modern high speed networks, since it can easily conceal itself due to its similarity with legitimate traffic, and so eluding current anomaly based detection methods.
