神經(jīng)網(wǎng)絡(luò)在入侵檢測(cè)系統(tǒng)中的應(yīng)用

本文簡(jiǎn)要分析了當(dāng)前的幾種入侵檢測(cè)方法，指出了將神經(jīng)網(wǎng)絡(luò)應(yīng)用于入侵檢測(cè)系統(tǒng)的優(yōu)越性。重點(diǎn)介紹了LVQ神經(jīng)網(wǎng)絡(luò)的結(jié)構(gòu)及其學(xué)習(xí)算法，提出了將LVQ 神經(jīng)網(wǎng)絡(luò)用于入侵檢測(cè)系統(tǒng)的方法，并給出了基于LVQ 神經(jīng)網(wǎng)絡(luò)的網(wǎng)絡(luò)入侵檢測(cè)系統(tǒng)模型結(jié)構(gòu)。最后，用matlab 進(jìn)行了仿真實(shí)驗(yàn)。結(jié)果表明，運(yùn)用LVQ 神經(jīng)網(wǎng)絡(luò)檢測(cè)入侵，可以達(dá)到較高的準(zhǔn)確檢測(cè)率，是一種有效的入侵檢測(cè)手段。

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.
