Project Summary: An attacker often selects a target machine only after broad scans to identify all vulnerable machines within a certain range of IP addresses. Unfortunately, current network routers often obscure scanning activity, since the routers will drop any scanning traffic directed toward a machine that does not actually exist. With this "loss" of scanning traffic, it is much harder for a security analyst to identify the scan in the first place or understand its scope. At the same time, however, routers do generate error messages (Internet Control Message Protocol (ICMP) Unreachable) when traffic is directed at nonexistent machines. By collecting these error messages, IRIA can provide security analysts with a much better view of scanning activity, allowing them to detect impending attacks that they might otherwise miss.
