摘　　要：为了克服当前系统对多级光交换网络安全防护效果不佳、评估可靠性轿差以及时间过长等问题,提出并设计了多级光交换网络安全防护系统。对系统接口模块、风险评估与预警业务管理模块、系统管理模块和系统知识库管理模块的进行了分析,设计了系统框架,分析了网络安全防护系统框架中的各个模块及其子模块功能,并采用符合性检查分析方法量化系统终端域、管道域和业务域的风险点,给出了网络安全风险评估与预警业务流程;依据该流程结合专家支持度法与最小均差法筛选了影响网络安全防护的主要指标因素,并从宏观角度建立了网络安全防护层次化指标体系;基于该指标体系采用数据挖掘技术中的主观层次分析法和客观熵值法评估网络风险,确定风险等级,实现了网络安全防护系统设计。通过实证分析实验结果,设计系统具有评估可靠性较高、误差较低、响应时间较快的优点,有利于实现网络安全风险实时评估和及时预警。In order to overcome the problems of poor security protection of multi-level optical switching networks, evaluation of the reliability of the car and long time,the multi-level optical switching network security protection system is proposed and designed.The system interface module,risk assessment and early warning business management mod- ule,system management module and system knowledge base management module are analyzed. The system framework is designed. The functions of each module and its sub-modules in the network security protection system framework are analyzed.The compliance check analysis method is used to quantify the risk points of the system terminal domain,pipe- line domain and service domain,and the network security risk assessment and early warning business process is given. According to the process,the main support factors affecting network security protection are screened by combining the expert support method and the minimum mean difference method,and the hierarchical index system of network security protection is established from a macro perspective.Based on the index system,subjective analytic hierarchy process and objective entropy method in data mining technology are used to evaluate network risk,determine risk level,and realize network security protection system design.Through the empirical analysis of the experimental results,the design system has the advantages of high reliability,low error and fast response time,which is conducive to real-time assessment and timely warning of network security risks.
