摘 要: 提出了一种基于云模型信息系统脆弱性分析方法。采用云模型,将信息系统脆弱性影响因素的自然语言评价映射为可细微变化的不同云滴,并实现了定性定量之间的不确定性转换,在此基础上,结合关联分析法对脆弱性影响因素权重进行挖掘,客观反映出各因素对脆弱性的影响程度。通过实例分析,验证了方法的有效性,结果接近实际。 A vulnerability analysis method of information system based on cloud model is proposed in this pa-per.The qualitative linguistic words about vulnerability factors of information system are mapped into fine-change-able cloud drops,and achieved uncertain conversion between qualitative and quantitative by cloud mode.Then,combined with the correlation analysis method,the weights of vulnerability factors are mined,and the influence of factors on vulnerability are reflected objectively.The validity of the method is proofed through an example analysis in this paper,and the results are more approach to the real status.
