Yin Hao, academician of the Chinese Academy of Sciences: 5G+ industry application security solutions are fragmented, which is not conducive to rapid deployment. News on December 12 (Yan Yi) As a comprehensive and leading technology in the field of new generation information and communication technology, 5G is the core content of new infrastructure and a key engine for the development of the digital economy. Currently, global 5G is showing a rapid development trend. my country's 5G integrated application multi-subject ecosystem has initially taken shape and is developing well. However, large-scale application of 5G still faces many challenges. At the China 5G Development Conference held today, Yin Hao, an academician of the Chinese Academy of Sciences, gave a speech and pointed out that in terms of 5G+ industry application security, although 5G communication network security and equipment security capabilities have been improved, and the foundation security of 5G networks has been guaranteed to a certain extent, 5G converged application security still faces some problems in the face of complex vertical industry security requirements. Problem 1: Security requirements are unclear. Some industries have insufficient risk awareness and understanding of 5G converged application security, and their security requirements are unclear. The mapping relationship between industry security needs and 5G network security supply capabilities is unclear. Problem 2: Solution fragmentation. One scenario, one solution, one service is not conducive to rapid and synchronous deployment of security capabilities. Customized solutions are costly and difficult to implement. Question 3: Supply capacity needs to be improved. Some industry scenarios have strict requirements on network security and reliability, and existing 5G application security services and products cannot fully meet their needs. In this regard, Yin Hao proposed that the innovation capabilities of security technology and applications should be continuously enhanced. In terms of traditional network security protection, new security technologies, security solutions, and testing and evaluation, it is recommended that all parties in the industry collaborate to strengthen security technology innovation, enhance network security supply capabilities, and drive the overall improvement of 5G application security technology and product supply capabilities. The first is to upgrade traditional network security protection solutions. Consolidate and optimize security protection technologies such as next-generation firewalls, intrusion detection, and situational awareness, and improve security supply capabilities such as edge computing application platform security. The second is to use new trusted access and endogenous defense technologies. Try to apply the zero-trust model, Secure Access Service Edge (SASE), trusted computing, cryptography, etc. in private network trusted access and transmission security. The third is to launch a 5G converged application data security solution. Data security risk identification and data security protection based on big data analysis. Solve issues such as sensitive data and privacy protection, and data flow security caused by 5G applications. The fourth is to study security testing and evaluation technologies. Research breakthrough requirements, methods and technical means for security evaluation of 5G networks and applications. Verify the security compliance and effectiveness of security defense capabilities of 5G converged applications. Yin Hao emphasized: Development and security are two sides of the same coin and complement each other. The deep integration of 5G and vertical fields has led to the intertwining of IT, CT, and OT security issues. Standardized, mutually trustworthy, efficient and flexible security technologies and management methods are needed to provide solid security guarantees for the development of 5G industry applications. In terms of converged application security, it is necessary to build converged application security capabilities on the basis of 5G basic network security to ensure the safety and reliability of 5G converged application networks; in terms of technology industry security, it is necessary to develop common security products and services, synchronize and rapidly deploy security capabilities, and ensure rapid deployment of security capabilities under differentiated needs; in terms of security management mechanisms, it is necessary to unify cross-industry security management requirements, clarify the boundaries of security responsibilities of industry entities, and ensure that cross-industry security responsibilities are clear and traceable
