In recent years, Intrusion Detection System (IDS) has become one of the hottest research areas in computer security. It is an important detection technology and is used as a countermeasure to preserve data integrity and system availability during an intrusion. When an intruder attempts to break into an information system or performs an action not legally allowed, the authors refer to this activity as an intrusion. IDSs can also be divided into two groups depending on where they look for intrusive behavior: Network-based IDS (NIDS) and Host-based IDS.
