光纤网络安全威胁指数的分析研究

Analysis and Research on Security Threat Index of Optical Fiber Network

为了对光纤网络中各种威胁提前预警,提出一种层级化安全威胁指数分析方法研究,首先基于光纤网络中的层级关系,构建一种网络安全评估模型;分别量化计算光纤网络系统威胁指数、主机威胁指数及服务层威胁指数;进而确定带宽占用率、网络威胁严重度等重要参数指标,实现对光纤网络中各种威胁的科学评估和提前预警。仿真实验通过分析典型的网络攻击威胁指数的变化趋势,证明了提出分析方法可以真实合理地揭示网络威胁的变化规律,具有较强的实用性。

In order to advance warning of threats to optical fiber network, proposes a hierarchical security threat index analysis method, based on the hierarchical relationship in the fiber network, build a network security evaluation model respectively; quantitative calculation of optical fiber network system, the host threat index threat index and service threat index; and then determine the bandwidth occupancy rate,network threat severity of other important parameters, to achieve a variety of threats in the fiber network evaluation and early warning. Through the analysis of the change trend of the typical network attack threat index, it is proved that the analysis method can reveal the change rule of the network threat reasonably and effectively.
