摘要
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。
For the host system-oriented static security assessment methods could not accurately evaluate the security flaws of host system in the network, a host system-oriented dynamic security quantitative assessment method is proposed. This method selects assessment factors from damage degrees of the host state and data, and based on the different features of assessment factors, the different quantitative algorithms are designed. In order to verify the reasonableness, effectiveness and feasibility of the method, an evaluation model of this method is constructed. The experimental results indicate that the assessment method could more accurately and objectively evaluate the security of host system in the network.
