Review on anomaly based network intrusion detection system

In computer system and network, Intrusion detection is an important research area. A lot of mechanisms are available for detect the network intrusion, but that is not able to identify the new kind of attacks. Various techniques have already been implemented for finding and categorizing intrusions. The Intrusion Detection system (IDS) is two types, namely Network based IDS and Host IDS (HIDS). The manual classification of network data inspection is time consuming task, expensive as well as repetitive job. IDS mechanism is very helpful to find the network attacks and anomalies. In IDS, data mining methods is broadly used for extracting useful information from the massive amount dataset. This paper presents the investigation of different techniques and intrusion classification on KDD Cup 99 dataset. So, by classifying the different network issues a new and effective technique is implemented which can categorize and identify intrusions in the KDD Cup 99 dataset.
