摘　　要：网络安全等级评价是信息系统等级保护的关键,进行网络安全等级评价需要依据网络安全等级保护的国家标准或行业标准建立指标体系,并设置指标权重,选择合适的模型进行综合评判。基于层次分析法和粗糙集理论对指标进行综合赋权,消除了指标权重设置的主观性和样本数据的突发性。以灰色关联度为测度去评价指标数列与目标数列的关联程度,更能体现信息系统实际网络安全水平与评价标准之间的符合度。实例分析表明,该方法能够有效地对网络安全等级进行综合评价。Network security grade evaluation is the key of information system grade protection,to evaluate the grade of network security,it is necessary to establish an index system according to the national or industrial standards of network security grade protection,set index weights,and select an appropriate model for comprehensive evaluation.Based on the analytic hierarchy process and rough set theory,the index is comprehensively weighted,which overcomes the subjectivity of index weight setting and the burst of sample data.The correlation degree of the number series and the target sequence is measured by the grey correlation degree,and the coincidence degree between the actual network security level and the evaluation standard is more reflected.The example shows that the proposed method can effectively evaluate the network security grade.
