Study Of A Distributed Network-based Intrusion Detection Systems

With the development of Internet and the tendency of information globalization,modern computer and network systems are plagued by security and privacy vulnerabilities.In order to do this, we can improve computer and network security through the useof computer security tools such as Intrusion Detection System, which can detect the attack in real time, suppress the attack nearly absolutely and diagnose the system fault promptly.we analyse the conditiong and security of computer system, we discuss the fimiliar intrusion method, based of analyticing technicof intrusion detection system,we put forward a based network distributed intrusion detection system and realiztiong method in the subsystem.we adopt abnormity and misuse detection method, systems have more improvement.
