基于层次分析和模糊数学的网络安全评价模型

为了对计算机网络进行比较全面、准确、定量的评价,应用系统工程的理论和方法,识别、分析和评价网络信息安全固有或潜在的风险发生的可能性和危险因素,建立了基于硬件、软件及外部环境的网络安全风险多层综合评价指标体系,给出了基于层次分析和模糊数学的网络安全综合评价数学模型.在该模型中,若给出指标体系低层的各模糊变换矩阵和各层的权矩阵,便可求得任意层的和最终的综合评判结果,避免了因素过多时难以分配权重的弊病,并给出了多层模糊综合评价的N-S流程图.

Model of network security comprehensive evaluation based on analytic hierarchy process and fuzzing mathematics

For carrying on more overall,accurate and quantitative evaluation f or the computer network,applying system engineering theory and method discern, analysing and appraising the dangerous factor and possibility happening about th e network information safe inherent or potential risk,synthesis evaluation inde x system could be established based on hardware and software and external enviro nment condition.The comprehensive evaluation math model based on analytic hiera rchy process and fuzzy math of network security had been provided.In the model,if fuzzy relation matrix of lowest layer is given,and the power matrix of all layer provided,then it can acquire comprehensive evaluation results of all lay er,and the final comprehensive evaluation result can be obtained avoiding probl em of power distribution,and the N-S flow chart of multi-layer fuzzy comprehe nsive evaluation had been provided.
