摘要
针对5G+工业互联网隔离方案,行业调研统计数据显示5G+工业互联网在5G 2B应用中占比较大,用户对网络安全尤为关注,特别是公网专网如何有效隔离。首先通过对目前5G ToB专网网络架构进行分析,从终端、网络、边缘MEC、企业私有云、运维管理5个方面分别分析网络存在的风险。其次针对网络侧存在的风险,为满足用户相关安全要求,提出通过无线基站广播新PLMN、TAI+PCF白名单、TAI+切片三种隔离方案并进行可操作性分析,对TAI+切片方案进行了重点阐述。最后通过某工厂5G+工业互联网实际案例对TAI+切片方案进行了验证,得出在现阶段该方案既满足公网专网隔离相关安全要求,同时具备可快速实施性的结论。
For the 5G+industrial internet isolation scheme,industry research statistics show that 5G+industrial internet accounts for a relatively large proportion of 5G 2B applications,and users are particularly concerned about network security,especially how to effectively isolate public and private networks.First of all,based on the current 5G To B private network architecture,network risks are analyzed from five aspects:terminal,network,edge MEC,enterprise private cloud,and operation and maintenance management.Next,in view of the risks on the network side,three isolation schemes including new PLMN,TAI+PCF white list,and TAI+slicing through wireless base stations,are proposed to meet the relevant security requirements of users,and their operability is analyzed,especially the TAI+slicing scheme.Finally,the TAI+slice scheme is tested through a practical case of 5G+industrial internet in a factory,which demonstrates that at the present stage,the scheme not only meets the security requirements related to public and private network isolation,but also can be quickly implemented.
