The intrusion detection systems are classified as Network based or Host based attacks. The network based attack may be either misuse or anomaly based attacks. The network based attacks are detected from the interconnection of computer systems. The system is able to communicate with each other, so that the attack is sent from one computer system to another computer system by the way of routers a...
