Abstract： Abstract： With the increasingly serious network attacks against CNC machine tools, the secure supply of CNC machine tools based on supply-side has become one of the important concerns of the road to manufacturing power.Based on the pain points of the industry, this paper solves the urgent security problems of CNC machine tools and realizes demand-side security. This paper designs an industrial firewall system which combines the security mechanisms such as “NC code anomaly detection”, “NC code virus detection” and “anti-collision detection”at the same time,and gives specific protective measures and suggestions around secure communication network, secure area boundary, secure computing environment, security management center,special protective equipment.Therefore, the research design and solutions in this paper closely serve the national strategic needs such as Manufacturing Power and Digital China.
