针对主机系统静态安全评价方法不能准确评价网络中主机系统安全性的缺陷,文中提出了一种主机系统动态安全性的量化评估方法,该方法从主机状态受损度和数据受损度两个方面选取评价指标,并根据不同的指标特征设计不同的量化算法。为了验证该评价方法的合理性、有效性和可行性,设计了该方法的一个评估模型,初步实验表明,该评估方法能够更准确客观的评价网络中主机系统的安全性。
Aiming at the defect that the host system static safety evaluation method can not accurately evaluate the host system security in the network, a quantitative evaluation method of the host system dynamic security is proposed in this paper. The method is based on two aspects: the host state damage degree and the data damage degree Select the evaluation index, and design different quantization algorithms according to different index features. In order to verify the rationality, validity and feasibility of the evaluation method, an evaluation model of the method is designed. The preliminary experiments show that the evaluation method can evaluate the security of the host system in the network more accurately and objectively.
