Intrusion Detection System used to discover attacks against computers and network Infrastructures. There are many techniques used to determine the IDS such as Outlier Detection Schemes for Anomaly Detection, K-Mean Clustering of monitoring data, classification detection and outlier detection. The data mining approaches help to determine what meets the criteria as an intrusion versus normal traffic, whether a system uses anomaly detection, misuse detection, target monitoring, or stealth probes. This paper attempts to evaluate, categorize, compares and summarizes the performance of data mining techniques to detect the intrusion.
