层次分析法在电网信息系统安全评估分析中的应用

Research on Grid Information System Security Evaluation Based on AHP

信息系统安全评估中的指标分配是评估过程中一项重要活动。介绍了层次分析法的原理及其在电网信息系统安全评估指标分配中的应用过程,包括评估的层次接口模型的建立,评估系统中各层元素相对权值的确定,各评估模块相对于系统安全的组合权重的确定。最后结合工作经验,对开展电网信息系统安全评估给出了思考与建议。

The weight distribution is an important factor as to information system security evaluation.This paper describes the principle of AHP and its application in grid security evaluation for deciding weight,which includes establishing AHP interface model,and puts forward the method for computing relative weight of each layer.Finally,combining with practical work experience,some advices for grid information system security evaluation was given.
