Abstract: The integration of 5G and the industrial Internet faces numerous security issues such as access security, network security, and data security, and there is an urgent need for new security technologies to address these issues. This paper summarizes the security policies, standards and industrial development of the Industrial Internet for 5G network, studies the security threats faced by the Industrial Internet for 5G network in terms of terminal, network, cloud platform and data security, and finally analyzes the security technologies of the Industrial Internet for 5G network in terms of terminal, network, cloud platform and data security. The security technology solution for the 5G-oriented industrial Internet needs to be based on the actual application scenarios of the industrial Internet, introduce protection technologies from multiple dimensions including terminals, networks, cloud platforms, and data security, construct a comprehensive protection system, prevent security threats, and enhance the level of security protection.
