随着信息技术的快速发展,油气SCADA系统正面临更加严重的信息安全问题。因此,本文在分析和研究了油气SCADA系统事前、事中、事后信息安全评价的条件因素之后,将评价指标映射到因素上,然后建立了基于因素空间理论的油气SCADA系统信息安全评价因素藤网模型,引入云模型推理对评价模型中的事中因素进行评价,并通过MATLAB软件实现云模型推理算法。实验结果表明,基于云模型的推理方法能够很好地实现对油气SCADA系统中的事中因素的评价,为油气SCADA系统信息安全评价提供了一种新思路。
With the rapid development of information technology, oil and gas SCADA systems are facing more serious information security problems. Therefore, after analyzing and studying the condition factors of the information security evaluation before, during and after the oil-gas SCADA system, the paper maps the evaluation index to the factors, and then establishes the information security evaluation factors of the SCADA system based on the factor space theory. Model, cloud model inference is introduced to evaluate the factors in the evaluation model, and the cloud model inference algorithm is implemented by MATLAB software. The experimental results show that the inference method based on cloud model can well evaluate the factors in SCADA system and provide a new idea for information security evaluation of SCADA system.
