摘　　要：信息技术的迅猛发展,油气SCADA系统的信息随时可能泄露,所以有必要对其进行安全评价。因此,本文根据SCADA系统的事件发生前期、中期、后期的防御技术体系,分析其评价指标,并将评价指标映射到因素上,然后采用了因素空间理论建立了信息安全评价的因素模型;针对评价模型的事中因素,引入云模型推理对其进行评价,并通过MATLAB软件实现云模型推理算法。实验结果表明,该方法达到了较好的评价效果,也为信息安全评价的方法提供了一种新思路。With the rapid development of information technology,the SCADA system of oil and gas is facing a more serious problem of information security.This paper firstly analyzed and studied the condition factors of information security evaluation on events happening before,during and after in the oil and gas SCADA system,mapped the evaluation indices onto the factors,then established a rattan net model of information security evaluation of oil and gas SCADA system based on the theory of factor space,and introduced theory of cloud model to evaluate the factor on events happening during in the evaluation model,finally achieves the cloud model reasoning algorithm through MATLAB.The experimental results show that the reasoning method based on cloud model can well realize the evaluation of the factors on events happening during in the oil and gas SCADA system,which provides a new way for information security evaluation of oil and gas SCADA system.
