电子政务外网网络安全指标体系配置研究

Research on Configuration of Index System of E-government Extranet Security

该文通过对现有网络安全指标体系进行研究,针对电子政务外网的特点,考虑所有影响网络安全的因素后,建立了一个全面的通用网络安全指标体系,为电子政务外网的网络安全态势评估提供依据。通过对通用指标体系的裁剪,满足用户对不同的设备的具体需求,针对网络上不同逻辑组,文章设计了态势的聚集算法,该算法能够识别电子政务外网逻辑组下的资产并能对这些资产的安全态势进行聚合,最后通过一个实例验证了该指标体系模型的科学性与合理性。

Through the research of existing network security index system, considering the characteristics of e-government extranet and all the factors affecting network security, in this paper, a comprehensive common index system of network security was established in this paper to provide the basis for the evaluation of the e-government extranet situation. The specific needs of users to different devices were satisfied by the cutting of the common index system. An aggregation algorithm of the situation was designed for different Logical groups on the network. This algorithm can identify the assets which were belongs to the logic groups of the e-government exlranet and then to aggregate the situation of these assets. Finally, an example was given to verify the scientificity and rationality of index system model.
