5G在特殊行业应用的安全风险及防御措施

Security Risks and Defense Measures for 5G Applications in Special Industry

5G以超大带宽、超广连接、超低时延的3大特征,为各行各业带来更广阔的发展空间,成为全球发展的重点。相比之前的移动通信网络,5G网络对安全机制考虑更加充分,但其安全体系设计主要面向公众用户,与特殊行业用户的高安全需求存在一定的差距,如何构建5G安全防护系统成为特殊行业用户的迫切需求。首先,梳理了国内外5G安全政策;其次,基于特殊行业的高安全性要求,建议其采用专网网络模式,分析了5G专网在特殊行业应用带来的安全风险,并提出了一种适用于特殊行业应用的5G安全总体框架;最后,基于该框架提出针对性的安全防御措施,为5G在特殊行业的应用提供参考。

With the three characteristics of ultra-large bandwidth,ultra-wide connection and ultra-low delay,5G brings broader development space for all walks of life and becomes the focus of global development.Compared with previous mobile communication networks,5G networks consider the security mechanism more fully,but its security system design is mainly oriented to public users,and there is a certain gap with the high security needs of users in special industries.How to build a 5G security protection system has become an urgent demand of users in special industries.First,this paper reviews 5G security policies at home and abroad.Secondly,based on the high security requirements of special industries,it suggests to adopt the private network mode.Thirdly,it analyzes the security risks brought by the applications of 5G private network in special industries,and proposes a general 5G security framework suitable for special industry applications.Finally,based on the framework,it proposes the targeted security defense measures and provides reference for the applications of 5G in specific industries.
