Abstract: Pharmaceutical industry usually has complicated and strict technological process and advanced production equipment. Automation, networking and information technology are developing rapidly in pharmaceutical industry. MES, SCADA and other systems are widely used in pharmaceutical enterprises. The network system covering production control and information management has also been applied in all aspects of pharmaceutical enterprise affairs. As a result, the importance of network security and control security to pharmaceutical industry has become more and more prominent. Therefore, building a multilevel security architecture is an important guarantee for pharmaceutical enterprise network system. Aiming at the characteristics of MES and SCADA systems in pharmaceutical industry and combining with the key production processes and production processes of pharmaceutical enterprises, this paper analyzed the security protection problems of industrial control network faced by pharmaceutical enterprises, studied the security protection technologies and strategies suitable for industrial control network of pharmaceutical enterprises, and put forward the pertinent security protection technologies. The technical framework and detailed design are also given in it.
