With the traditional industrial control systems and equipment with poor protection capabilities connected to the Internet, mass industrial control systems and business systems have become the focus of cyber attacks.
Yang Yuyan, deputy director of the Network Security Administration of the Ministry of Industry and Information Technology, said: "The deep integration of the Internet and industry has broken the relatively closed and credible environment of the traditional industrial sector and penetrated the security threat of the Internet into the industrial field. The cyberattack went straight to the production line. ”
Fan Yuan, chairman of Hangzhou Anheng Information Technology Co., Ltd., said that the biggest threat to the industrial environment is proprietary targeted malicious code, such as the well-known earthquakes, flames, etc., which are attacked by engineers in industrial control systems. Hosts such as stations, operator stations, servers, and controllers such as DCS and PLC. The purpose is to directly invade the host and the field control equipment by maliciously infiltrating into the on-site layer control network to achieve the purpose of destroying the industrial production process and damaging the physical entity.
Only last year, the Network Security Administration of the Ministry of Industry and Information Technology entrusted relevant professional organizations to discover more than 2,000 security threats during the security inspection and evaluation of more than 20 typical industrial enterprises and industrial Internet platform enterprises.
Wang Xiaoyun, an academician of the Chinese Academy of Sciences, said: "Chinese industrial control system consists of various automation control components, and the operating environment is relatively backward. A large number of industrial control systems use private protocol communication, lacking security design and demonstration. In most cases, security is sacrificed, and stability is exchanged. The maintenance of safety updates is not timely, which is related to the level of science and technology in China, especially the inability to achieve self-control."
