Application of Neural Network in Intrusion Detection System Li Dong-mei , WANG Jie
Abstract：The paper analyzes several kinds of intrusion detection technique, and points out the superiority of applying neural network in intrusion detection system. It mostly introduces the structure and study arithmetic of LVQ neural network, puts forward the method applying LVQ neural network in intrusion detection system and gives the structure of intrusion detection system based on LVQ neural network. In the end, a simulation experiment in MATLAB has been carried out. The result expresses that the intrusion detection system based on LVQ neural network can attain a higher accurate examination rate. So it is an effective intrusion detection method.
Key words：intrusion detection system; neural network; LVQ neural network
