灰色聚类评估模型在安全评估中的应用

针对大多数安全评估模型通用性差的问题，利用灰色聚类理论，建立了一个新的信息系统安全评估模型. 提出了采用灰色聚类决策对系统安全状态进行评估的方法,给出了系统安全状态的灰色分类,并构造了灰类的白化权函数. 结合具体实例说明了该模型的应用，并运用灵敏度概念，分析评估结果的稳定性和可靠性.

Grey Clustering Evaluation Model and Its Application in Security Evaluation

Aiming at the poor generality for most models of security evaluation, a novel security evaluation model of information system was established based on the grey clustering theory. The evaluation of system security state using grey clustering decision-making method was put forward. The grey classes of system security state were given, and the whitenization weight function of grey classes was formulated. This model’s application was illustrated by an evaluation example, and the stability and reliability of evaluation results were analyzed according to the conception of sensitivity.
