摘要: 网络功能虚拟化(NFV)是未来电信网络演进的方向和技术基础,也是5G核心网关键技术之一。随着NFV技术的成熟和5G步伐的临近,NFV将迎来大规模商用浪潮。但NFV技术存在的一些安全问题尚未得到有效解决,相关研究还比较滞后。本文从NFV架构的基础设施层、Hypervisor、虚机、虚拟网元层和编排管理5 个方面分析了NFV技术面临的安全风险和威胁,提出了一些可用于缓解NFV安全风险和威胁的技术及措施,并对NFV未来发展之路提出了一些思考和建议。

Abstract: Network Function Virtualization (NFV) is the basic technology of future telecom networking and the trend for network evolution. As this technology is becoming mature and the 5G era is coming, NFV will be provisioned on a large scale in the near future. This article introduces the advantages of NFV technology and its trend of deployment as well, and also analyses its risks from NFV’s 5 key components: infrastructure layer, Hypervisor, VM, VNF layer and MANO. In order to mitigate these risks, this article has proposed some key security technologies and measures.
