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.
