Research on network intrusion detection has produced a number of interesting results. In this paper, the author look back to the NetSTAT system, which was presented at ACSAC in 1998. In addition to describing the original system, the author discuss some historical context, with reference to well-known evaluation efforts and to the evolution of network intrusion detection into a broader field that includes malware detection and the analysis of malicious behavior. Network Intrusion Detection Systems (NIDSs) have evolved from their academic beginnings into mainstream commercial products, and network intrusion detection is now considered a "Mature technology."
