网络安全风险可视化应用研究

Network Security Risk Fusion Model Based on Data Field

针对目前网络安全态势全局信息掌握的不足,建立网络环境下的安全态势显示模型,基于全局网络定位（GNP思想）,通过网络拓扑的坐标化来实现网络风险场的构建,利用主机风险评估技术和网络环境下的风险融合技术,研究网络环境下的风险态势可视化,为网络管理员全局掌握网络安全风险态势,提供直观的安全态势视图,为风险阻断和策略制定提供辅助。

As there are shortcomings of current network security risk evaluation based on global information,we build a new network security risk amalgamation model which evaluates network security factors from local to global.Based on the fuzzy evaluation and stastitical analysis,we use GNP（Global Network Position） to plot network topology,and then according to add all the relevant factors between important nodes with weight,we implement risk amalgamation effect of relevant nodes under the idea of Data Field.After building the Data Field,we found that our new model could reflect the law of risk amalgation correctly,and control the tendency of the global network security risk,and supply a straighter graph of security tendency for administrators to terminate risk propagation and set policies.
