模糊综合评判法在电力企业网络信息安全评估中的应用

Application of fuzzy comprehensive evaluation method in network information security assessment of electric power enterprises

现今电力企业已经实现了信息化的经营生产,网络信息安全评估工作的重要性日益显著。采用二级模糊综合评判法对一种基于PDRR模型的电力企业网络信息安全系统进行安全等级评估,并采用Delphi法对评估过程中电力影响企业网络安全的各项因素的权重系数进行确定,通过对评估结果的客观分析,找出电力企业网络信息安全系统中存在的突出问题,做出相应的安全加固。验证结果表明,优化后的网络信息安全模型更为坚固,实用性和可操作性都显著提升,有效提高了电力企业的网络信息安全等级,可以作为其他电力企业网络信息安全建设的有利参照。

Nowadays,electric power enterprises have realized the operation and production of information technology,and the importance of network information security evaluation is more and more obvious.Two-level fuzzy comprehensive evaluation method was used to evaluate the security level of network information security system of power enterprises based on PRDD model,and Delphi method was used to determine the weight coefficients of various factors of network security of power enterprises in the evaluation process.Through objective analysis of the evaluation results,the network credit of power enterprises was found out.The prominent problems existing in the informa-tion security system should be solved and the corresponding security reinforcement scheme should be formulated.The validation results show that the optimized network information security model is more robust,practicability and operability are significantly improved,which effectively improve the network information security level of power enterprises,and can be used as a favorable reference for the construction of network information security of other power enterprises.
