The essence of EDID is to set up a normal behavior fuzzy sub collection A on the basis of watching the normal system transfer of the privilege process, and set up a fuzzy sub collection B with real time transfer array, then detect with the principle of minimum distance in fuzzy discernmethodThe innovation point of this paper is : Put forward the method of EDID, can not only reduce efficiently false positive rate and false negative rate, also make real time intrusion detection to become possibility; have independent and complete character database, according to the classification of monitoring program, design normal behavior and anomaly behavior etc., have raised the strongness of IDS; Use tree type structure to preservation the character database, have saved greatly stock space; in detection invade , carry out frequency prior principle, prior analysis and handling the behavior feature of high frequency in information table, have raised efficiency and the speed of detection, make real time intrusion detection to become possibility; have at the same time realized anomaly intrusion detection and misuse intrusion detection, have remedied deficiency of unitary detection method.

本文的创新点是：通过对特权进程的系统调用及参数序列的研究，提出了基于Euclidean距离的入侵检测方法EDID，不仅能有效降低漏报率和误报率，而且使实时入侵检测成为可能；设计有独立而完整的特征数据库，根据被监控程序的类别，分别设计正常行为、异常行为等，提高了检测系统的强健性和可伸缩性；特征数据库按树型结构存储，大大节省了存储空间；在检测入侵时，实行频度优先原则，优先分析和处理信息表中的高频度行为特征，提高检测的速度和效率，使实时入侵检测成为可能；同时实现了异常入侵检测和误用入侵检测，弥补了单一检测方法的不足。

The algorithm can delete the subsequential sets using the weight and generate new candidate sequential sets using the infrequent sequential sets in the knowledge database. It needn't visit the old database again and again, so it can avoid the problem that candidate sequential sets are very large, and can decrease the run time and memory spaces. It improves the algorithm performance greatly.

该算法利用权值来归约子序列集和利用知识数据库中保留的最小非大序列集产生新的候选序列集，避免了重复遍历原始信息库而造成数据量太大的问题，从而缩短程序运行时间和节约数据存储空间，较好地改进了算法性能。
