【摘要】 针对网络安全性评价研究中的度量问题建立了基于ISO/IEC9126标准的网络安全指标体系模型。结合网络安全评价方法研究中的模糊性和不确定性等常见问题,首先以度量数据和各项指标计算公式为基础计算其指标值。其次,运用指标体系模型和模糊评价方法对评价指标进行模糊化处理。最后,结合各指标评价质量和模糊综合评价方法评价网络安全性。通过建立网络安全性评价模型,有效地解决了网络安全性的多指标评价问题,可用于指导相关人员进行网络安全方面改进。更多还原

【Abstract】 To measure network security,an indicator system model based on the international standards of ISO/IEC9126 is presented.According to the common problems of fuzzy and uncertainty in network security evaluation,the indicator value which are based on the real data and the calculating formula is obtained.Then the indicator system model and the fuzzy evaluation methods are applied to the network security indicator evaluation.At last,the quality of each indicator and the fuzzy synthesized evaluation method are applied to evaluate the security of the network.By making the network security evaluation model,the network security multi-indicator evaluation is implemented smoothly,and the evaluation results can be used in the network security improvement.更多还原
