摘要
在5G时代,使用SDN、NFV等虚拟化技术,在实现资源利用率提升、网络运营成本降低的同时,也面临着物理防御边界消失、系统暴露面加大、受攻击面广等更为复杂的虚拟化安全问题。在对SDN、NFV等5G虚拟化关键技术及安全风险进行分析基础上,提出了面向5G网络虚拟化技术的安全策略,有助于提升网络虚拟化技术安全水平,降低风险隐患。
In 5G era,because of the usage of SDN/NFV based on virtual technologies,it faces more complex virtual security problems(such as disappearance of physical defense boundaries,the expansion of system exposure surface,wide attack surface,and etc),when resource utilization ratio is improved and network operating cost is reduced.On basis of research on 5G key technologies and its security risks,this paper proposes security countermeasures and technologies oriented for 5G network virtual technology,which would be help to improve security level of network virtual technologies and reduce risks.
