摘　　要： 对网络安全管理系统建模及进行可生存性分析是一个非常重要的研究课题,但对于大型网络如何建模和评估生存性,尚无较好解决的方案。现存的两种评估网络安全管理系统的生存性的方法存在较大局限性:割点法无法对大型网络进行分析;Monte-Carlo法只能区间估计,得不到准确值。提出了连通支路的分析方法,使用成熟的数学模型进行实现,并给出编程算法。对拓扑变化给生存性的影响做出分析,为建立完善的生存性分析平台打下了良好的基础。 Modeling and analyzing the survivability of network security management systems is a very important research hotspot, but there is no better solution for the large-scale network modeling and evaluation of survival. The limitation of the existing two methods for network security management systems is showed as the following： the cut-set method cannot analyze large network, and the Monte-Carlo method gives only the interzone evaluation, but not accurate results, A connected path method was proposed to calculate system survivability, in which the mathematics model was used and the program of the arithmetic was given. Then, a further analysis was given to the relations between survivability and power of single path. That will form a good foundation for building a perfect survivability analysis platform in future.
