Despite its strong reliability and security, 5G network, as an important cornerstone of critical information infrastructure and digital transformation, brings new security challenges and risks while opening a new era of Internet of everything.

  To get a correct understanding of 5G security issues, objective analysis is needed from the perspectives of technology and scenarios, as well as comprehensive assessment from the industrial ecological dimension.

   How do you view 5G security?

   As for 5G security issues, we should hold the development concept, system concept, objective concept and cooperation concept:

(1) Development philosophy. 5G is the latest achievement in the development of information technology, which reflects the historical trend and trend of global informatization development. The development of 5G should not be slowed down or delayed because of security risks. We should view security risks from the perspective of development, properly handle the relationship between development and security, and ensure that security and development are promoted in parallel.

(2) System concept. 5G technology has been integrated into various fields, and security risks are closely related to multiple subjects, which need to be viewed and dealt with the concept of comprehensive system. The development of 5G technology and application scenarios is broad, open, challenging and diversified. It not only needs to clarify the responsibilities and obligations of different actors in each link of the industrial chain such as network operators, equipment suppliers and industry application service providers, but also needs to strengthen the cooperation among them.

(3) Objective concept. Due to the integration of 5G with the Internet of things, artificial intelligence and other new technologies and new applications, more complex security problems will be brought about. Therefore, comprehensive assessment of 5G security risks needs to be carried out from an objective and neutral technical perspective. On the basis of the existing mature mechanisms and existing technological countermeasures, industrial innovation and technology research and development will gradually solve the problems.

(4) Cooperation concept. 5G security is a global challenge, and no one is immune. From previous global standards to a unified global standard in the era of 5G, the process of 5G is a vivid reflection of the innovation cooperation among all parties. We should also work together on security to strengthen innovation cooperation and jointly build a peaceful, safe, open and cooperative cyberspace.
