Therefore the security on the network becomes the major issue. To overcome this many intrusion detection approaches are used. Intrusion detection gives the confidentiality, integrity and security of a resource. Data mining is the one of technology applied to intrusion detection to detect the network attacks, to reduce the complexities and to get normal behavioral pattern.
Keywords: Intrusion Detection System, Data set, Data Mining Algorithms, Classification.
