摘　　要：针对缺乏网络服务级安全态势评价方法的现状,利用事件注入技术,充分考虑影响服务可用性与性能的重要因素,确立了反映网络服务级安全态势的三级指标体系,并提出一种基于模糊层次分析法(FAHP)的网络服务级安全态势评价方法,通过求出各指标对上一级指标的权重,结合多层次综合评价方法得到模糊最大隶属度向量,从而对网络服务级安全态势进行了量化分析。实验结果表明该方法能有效屏蔽具体服务及入侵行为细节,实现对网络服务级安全态势的定性描述和定量分析。Lacking of effective evaluation method of service-level network security situation, the event injection technique was introduced to select some important factors that reflected service availability and performance, a three-level index system of service-level network security situation was also established. Then an evaluation method of service-level network security situation based on Fuzzy Analytic Hierarchy Process （FAHP） was presented. Through the FAHP the index weight related to the higher level was calculated; combined with muhi-level fuzzy comprehensive evaluation, a quantitative analysis on servicelevel network security situation was finally got. Experimental results show that this approach can shield details from a specific service or an intrusion, and it is of high efficiency in qualitative description and quantitative analysis.
