The reseach results show that the focus on an IDS is to develop a new method that can decrease false alarms and to develop new criteria system for anIDS.
The architecture of an IDS(Intrusion Detection System) and the relevant technologies are discussed by analyzing the current IDS, including the architecture,collecting data method,data dealing method and evaluating criteria. The reseach results show that the focus on an IDS is to develop a new method that can decrease false alarms and to develop new criteria system for an IDS.
