Data caching method and device for industrial control network, terminal equipment and medium

The invention is applicable to the technical field of industrial control management, and particularly relates to a data caching method and device for an industrial control network, terminal equipmentand a medium. The method comprises the steps of obtaining first attack data of an industrial control network and attribute information of the first attack data; and obtaining candidate cache data of the first attack data according to the first attack data and the attribute information of the first attack data, and storing the candidate cache data of the first attack data into a preset cache library . By storing candidate cache data into a preset cache library, users conveniently call the data. Candidate cache data is directly extracted from a preset cache library in the subsequent access process. The attack data is prevented from being analyzed and processed again by subsequent access, so that the phenomenon of relatively high resource occupation of the terminal equipment due to multiple analysis and processing of
