It works\ud like a burglar alarm that goes off if someone tampers with or manages to get past other security mechanisms\ud such as authentication mechanisms and firewalls. An Intrusion Detection System (IDS) is a device or a software\ud application that monitors network or system activities for malicious activities or policy violations and produces\ud reports to a management station.Intrusion Detection System (IDS) has been used as a vital instrument in\ud defending the network from this malicious or abnormal activity..In this paper we are comparing host based and\ud network based IDS and various types of attacks possible on IDS
