| 摘 要： | 在分析信息系统中威胁、脆弱点、风险事件之间相互关系的基础上，引入了基于风险概率的自然权重概念；采用自然权重动态地计算各因素在评价过程中的权重，并给出了自然权重的计算方法；结合相应指标体系描述了自然权重的使用过程。实例表明该权重计算方法能够真实、客观地反映各影响因素在整个系统安全中的地位与作用，是一种切实可行的权重计算方法。

| Abstract: | According with the relationships of threats, vulnerabilities and risk events in information system,this paper introduced the natural weight based on risk probability to dynamically calculate the weight for specific indexes,and the presented calculation method of natural weight.It described the process of using the natural weight combining index system.The experiuneut shows that the natural weight can truthfully and objectively reflect the impact on security of information system. It is a feasible calculation method of weight. |
