In present scenario, everyone in this huge world is using internet to communicate with each other. Internet is now not only centered to the web mail or chat but also extended to the field of education, business, media and many more. The heuristic approach for efficient detection of intrusion is been proposed on this paper. The proposed framework uses new data preprocessing and filtration criteria which is data discretization to improve results of intrusion detection. It is more Accurate in comparison the existing methods. An overview of intrusion detection system is been presented. Also the present approaches for intrusion detection system are been described.
