一种安全操作系统风险评估模型

针对安全操作系统风险管理难以进行定量评判的问题，提出一种适用于安全操作系统风险等级定量评估的模型。通过引入风险矩阵法，将信息安全风险评估归纳为以专家矩阵、Borda法则和层次分析法为评估流程的风险等级评估模型，实现安全操作系统风险等级的定量评估，增强评估操作系统风险等级的客观性。通过实例应用对评估模型进行验证，结果表明该模型能有效评估出安全操作系统的风险等级。

Risk Assessment Model of Security Operating System

Aiming at the problem of security operating system risk management is difficult to evaluate quantitatively,this paper puts forward a suitable operating system security risk grade quantitatively evaluation model.Through introducing the risk matrix method,putting the information safety risk assessment as the risk evaluation model by experts matrix,Borda rule and Analytic Hierarchy Process（AHP） assess the risk assessment process,and achieve safe operation system risk management quantitative evaluation,enhance the objectivity of the operating system risk rank quantitative evaluation.In conclusion,the application evaluation model is validated through the examples,and the results show that the model can effectively assess the operating system security risk levels.
