摘要
针对信息系统安全风险分析的准确性问题,提出一种基于信息熵的信息系统安全风险分析方法。在此基础上构建了一种信息系统安全风险分析模型,并通过实例分析验证所提方法可有效应用于信息系统安全风险分析。
According to the accuracy problem of the information system security risk analysis,this paper proposed an information system security risk analysis method based on information entropy.The paper constructs an information system security risk analysis model and through the case analysis verified the proposed method can be effectively applied to information system security risk analysis.
