摘要
云环境中网络虚拟化已成为网络技术演进的重要方向,虚拟化网络环境面临的网络安全问题则成为当前网络安全研究的热点。虚拟化条件下的网络既面临传统网络中已存在的安全问题,也有引入虚拟化特性之后出现的一系列新问题。通过对网络中的各要素及其关系进行描述,分析了虚拟化网络环境的特性,进而分析了虚拟化网络环境面临的安全威胁,包括物理网络威胁、虚拟局域网威胁和虚拟网络威胁等。通过构建威胁矩阵进行网络安全风险分析,指出高、中、低等不同级别安全威胁的类型。针对典型的网络安全风险,给出了相应的安全防护对策。
Network virtualization has become the developing direction of the future network,the network security problem of the virtual network environment has become the hot spot of network security research. The network based on virtualization includes the security problems in traditional network as well as the new ones after virtualized. In order to do security risk analyses,the characteristics of the virtualized network environment has been analysed by describing the objects and the relations between them in the network. Then the security menace has been sum up and the risk matrix has been built. Based on these analyses,the corresponding defending countermeasures are put forward to solve the typical problems in the virtualized network environment.
