| 摘 要： | 利用模糊评判方法对网络安全进行风险评估，对各风险因素分别从风险发生的概率和风险产生的影响两方面进行评估，对风险因素的权重的确定，不是单凭主观评判，而是采用熵权系数法进行客观计算，通过实例分析可知，利用该方法可以方便地求出网络系统的风险度，实验结果符合实际。

| Abstract: | The method of fuzzy comprehensive judgment is applied to the risk assessment of the network security. Each risk actor is estimated in the aspects of probability and the influence. The weight of the risk actor is calculated objectively by the method of entropy weight coefficient, not only by subjective judgment. The study of the case shows that the risk degree of the network system can be conveniently found out with this method. The results are in accord with the reality. |
