光传输网安全风险分析及防御技术研究

Optical Transmission Network Security Risk Analysis and Defense Technology Research

光传输网承载物理层及链路层的数据传输,是所有通信网络的核心基础。因此,光传输网安全作为数字信息基础设施安全的关键组成部分,其重要性不言而喻。对光传输网的分层结构展开介绍,分析了不同层面的安全风险,并针对各层可能受到的安全威胁研究了相关的安全对策,最后对光传输网安全防护体系构建的关键点进行了总结。

The optical transmission network carries the data transmission of physical layer and link layer,which is the core foundation of all communication networks.Therefore,as an important component of digital information infrastructure security,the importance of optical transmission network security is self-evident.This paper introduces the hierarchical structure of optical transmission network,analyzes the security risks at different levels,studies the relevant security countermeasures for the possible security threats to each layer,and finally summarizes the key points of the construction of the optical transmission network security protection system.
