Abstract
A network intrusion detection system combines the normally sequential steps of protocol analysis, normalization, and signature matching through the use of a regular expression to speed the monitoring of network data. The regular expression also allows the creation of a superset matcher, permitting multiple stages of matching of increased accuracy to produce additional throughput gains.
