国外数字化工厂网络安全保障机制研究OA

A digital factory is a key industrial facility that integrates new generation information technology and advanced manu-facturing technology.It is also an important carrier for promoting the digital transformation of China's manufacturing industry and enhancing the country's technological and economic competitiveness.At the same time,due to the characteristics of networking,intelligence,and openness of digital factories,traditional network integrated security architecture is difficult to adapt to more com-plex business flows,supply chains,and constantly changing business models,becoming a major challenge for the digital transfor-mation of the manufacturing industry.How to ensure its secure and stable operation has become a focus of concern for governments and industries around the world.Takes the construction of Lockheed Martin digital factory as an example to study its digital trans-formation strategy,factory digital architecture,and analyze its industrial Internet of Things equipment connection communication framework(intelligent factory framework),as well as security measures in cloud platforms,wireless Internet of Things,network security governance,research and development operations,and other aspects.On this basis,comprehensive suggestions from multiple perspectives are proposed on how to strengthen the construction of network security protection mechanisms for digital fac-tories in key industries in China.
