Abstract:

A network defense system must balance both security and stability. To enhance its risk control capabilities, a comprehensive risk assessment model for the network defense system based on the combination of game theory and weight assignment is proposed. The risk evaluation index system is established through literature analysis, expert surveys, and factor analysis. The subjective and objective weights of the evaluation indices are calculated using the continuous ordered weighted average (COWA) and the entropy weight method (EWM). The optimal combination weights are determined using game theory, and the risk evaluation level of the network defense system is assessed using the fuzzy matter-element method. A case study of a local area network (LAN) project validates the model. The results demonstrate that the model is a useful reference for assessing the risk of network defense systems.

摘要:

网络防御系统具有兼顾安全性及稳定性需求的特点,为有效提升其风险控制能力,提出一种基于博弈论组合赋权构建网络防御系统综合风险评价模型。通过文献分析、专家调研及因子分析等方法建立网络防御系统风险评价指标体系,采用连续有序加权平均算子(COWA)和熵权法(EWM)计算风险评价指标主客观权重,引入博弈论确定最优组合权重,并运用模糊物元法确定网络防御系统风险评价等级。以某局域网平台项目为例,对评价模型进行了分析验证。结果表明,该模型能够为网络防御系统风险评价提供有效参考。
