An approach towards multilevel and multiagent based intrusion detection system

Due to massive expansion of network computer systemS it became very difficult to manage those systems. Now a day´s many intruders are present who take advantages of these internet facilities and that´s why many unauthorized access is done. Intrusion detection system detects intrusion and also detects the malicious attacks and if any suspicious behavior is found it generate an alarm to the administrator and stops the work. In this paper we improve the intrusion detection system and use the Multiagent concept with multilevel intrusion detection system. Here we store the attack types in the database and when any types is matched with this database then it detects the intrusion. By this process no unknown attacks are detected.
