随着云计算、移动互联网等新技术的发展和成熟,网络业务的多样化、基础资源能力的大力提升等给数据中心网络的可扩展性、可管理性、安全性等提出了新的要求。SDN体系架构的出现为目前网络问题的解决提供了新的方向,因而在产业界和研究领域得到了深入的研究和应用。 但随着SDN相关网络设备的出现,安全问题成为制约其发展的一个重要因素。本文首先分析了SDN架构的产生背景,阐述了SDN的网络技术架构原理及目前的发展现状;随后对SDN架构中的安全特点、安全威胁进行了分析;最后,提出了一种SDN架构下的安全技术框架,从威胁分析、防御规则、防御方法3个方面对SDN中的安全问题提出了建议。
With the rapid deve1opment of c1oud computing and mobi1e internet
the features that network exhibits
such as diversity
dec1are for urgent requirements for sca1abi1ity
manageabi1ity and security of the data center.The SDN architecture shows a promising way of dea1ing with the above requirements of network through revo1utionary innovation of the traditiona1 network architecture
which attracts great interest of companies and research institutes.However
according to the recent research and progress of SDN
security prob1em has not been addressed
which wi11 be a significant issue.Based on the situation
the basis of SDN
inc1uding the origination
architecture
standardization work and standardized protoco1
were described
and the security issue was a1so ana1yzed.In the security part
the exhibiting new features of security prob1em for SDN
were ana1yzed
by 1isting the undergoing work
and then the security threats in SDN were conc1uded.Fina11y
a suggested architecture for security research of SDN was proposed.
