The IEEE international conference on communications this week has several technical papers of interest to network security, although the most relevant weren't labeled network security. Detection and Preferential Dropping of High Bandwidth Unresponsive Flows by Chatranon, Labrador and Banerjee. Controlling Malicious Sources at Internet gateways by Chhabra, Joh, Saran and Shorey. But there are still issues about loading the bottleneck with even more processing during periods of extreme stress, handling distributed management domains, and handling distributed attacks. Scale affects everything on the Internet, including the response.
