Abstract: AbstractIn recent years, industrial control network security incidents have exploded in the world, involving many national basic industries such as electricity, petrochemicals, and nuclear facilities, causing a large amount of losses to the state and enterprises. The changes under the new concept of “twooriented integration” and “Made in China 2025” further aggravate the safety risks of industrial control systems. By exploring and analyzing the information security problems faced by industrial control systems used in the refining and chemical industry, this paper presents a security protection solution based on the network deployment structure in the industrial refinery industry.
