In 1988, SRI / CSLs Teresa Lunt, who improved Dennings intrusion detection model, and developed a IDES. The system includes an exception detector and an expert system, are used to model statistical anomaly and rule-based feature analysis and detection. Intrusion Detection System 1990 was a watershed in the history. This year, the University of California at Davis LT Heberlein, who developed a NSM. The system is the first time as a network flow directly to the audit data source, and therefore can not be unified format audit data into the case of monitoring heterogeneous hosts. Since then, the development of intrusion detection system opened a new chapter in history, was officially formed two camps: network-based IDS and host-based IDS. 1988 Morris worm incident, network security really caused the military, academia and enterprises attach great importance. U.S. Air Force, the National Security Agency and the Department of Energy jointly funded the Air Force Password Support Center, Lawrence Livermore National Laboratory, University of California, Davis, Haystack Labs, carry out the Distributed Intrusion Detection System, will be based on host-based Detection of network integrated together, the overall structure shown in Figure 3.
