What are the different types of IDSs?
There are many ways of describing IDSs. The primary descriptors are the system monitoring approaches, the analysis strategy and the timing of information sources and analysis. The system monitoring approaches are network-based, host-based, and applications-based. The analysis strategies are misuse detection and anomaly detection. The timing categories are interval-based (or batch mode) and real-time. The most common commercial IDSs are real-time network-based systems.
