本文通過分析現(xiàn)有入侵檢測技術(shù)的優(yōu)缺點，提出一種改進的聚類算法CLOPE將其應用
于網(wǎng)絡入侵檢測。該算法不需標準化數(shù)據(jù)，應用一種基于統(tǒng)計直方圖的全局準則函數(shù)進行聚類，特別適用于大規(guī)模數(shù)據(jù)。在運用該算法時，還優(yōu)化了收益值的計算，加快運行速度。實驗證明，該算法不同于一般的聚類算法，能大大提高入侵檢測的效率。

Abstract: This article through the analysis existing intrusion detection technology good and bad points, proposed one kind of improvement cluster algorithm CLOPE to apply to the network intrusion detection. This algorithm does not have to standardize the data, uses a kind of global criterion function based on the statistical histogram to depict clusters, specially is suitable for the large-scale data. When utilizes this algorithm, we optimized the income value computation, speeds up the running rate. The experiment proved that, this algorithm is different from the general cluster algorithm , it can improve and invade the efficiency measured greatly.
Keywords:Global criterion function,Cluster alogorithm,Intrusion detection system
