RADAR is a SDN-based Denial-of-Service defense system. It can detect and mitigate DDoS attack in realtime. We implement its prototype as a Floodlight module which contains the main framework and 3 detection examples on Crossfire, SYN flooding and amplification attack.
RADAR is a research project, and it is conducted in the Internet and Cloud Security Research Group. Our result is published in IEEE TIFS. See our paper for more details.
