"Real-Time Visualization of Network Attacks on High-Speed Links"


In this talk, we will see that malicious traffic flows such as denial-of-service attacks and various scanning activities can be visualized in an intuitive manner. A simple but novel idea of plotting a packet using its source IP address, destination IP address, and the destination port in a 3-dimensional space graphically reveals ongoing attacks. Leveraging this property, combined with the fact that only three header fields per each packet need to be examined, a fast attack detection and classification algorithm can be devised.
