Abstract
In the process of industrial Internet security situation analysis, affected by the perception model, the average approximation error of security assessment results is high. Therefore, an industrial Internet security evaluation technology based on digital twin is proposed. Design the industrial Internet assessment mode, design the industrial Internet technical framework according to the digital twin, and clarify the elements of security situation assessment. According to the sliding time window, the fuzzy knowledge base is established. The security situation awareness model is designed based on digital twin, combined with the calculation results of fuzzy closeness to improve the accuracy of automatic perception results. Establish a multi port access protocol and realize the industrial Internet security evaluation technology under the digital twin with the help of the backed up coded key file. The experimental results show that the accuracy of the evaluation results of the design method is always above 95%, the tamper-proof success rate is always above 95%, and the physical value difference between the final values is 0.10. Therefore, this method effectively improves the evaluation accuracy. and tamper-proof success rate, reducing the difference value, it effectively controls the deviation of Internet operation data, provides security, is feasible and effective.
