Intrusion detection at 100G

Driven by the growing data transfer needs of the scientific community and the standardization of the 100 Gbps Ethernet Specification, 100 Gbps is now becoming a reality for many HPC sites. This tenfold increase in bandwidth creates a number of significant technical challenges. We show that by using the heavy tail flow effect as a filter, it should be possible to perform active IDS analysis at this traffic rate using a cluster of commodity systems driven by a dedicated load balancing mechanism. Additionally, we examine the nature of current network traffic characteristics applying them to 100 Gpbs speeds.
