摘要
NFV通过标准化的业务和功能编排,使得在虚拟环境中运行网络成为可能。电信云基于NFV的架构与传统网络基础设施架构存在差异,这也导致了基础设施、网元的运行环境、网络部署和管理、安全等方面的改变,同时也带来了新的安全挑战。在此背景下提出了电信云的安全参考架构,在电信云关注的层级内,按照参考架构梳理了相关安全问题和风险,并针对性地给出了一些建议。
The telecommunication network can be established in a virtual environment via standardized orchestration of business and functions by NFV.There are differences between the telecom cloud based on the NFV architecture and the traditional network infrastructure,which leads to the changes in infrastructure,network element operating environment,network deployment and management,security and other aspects,and brings new security challenges at the same time.The security reference architecture of the telecom cloud is proposed.Within the level of telecom cloud,relevant security issues and risks are sorted out according to the reference architecture.Finally some suggestions are put forward.
