摘　　要：软件定义网络(Software Defined Network,SDN)在通信网络中的应用日益广泛,但其集中控制架构也带来新的安全挑战。文章深入剖析SDN架构下通信网络面临的安全威胁,包括控制器单点故障、拒绝服务攻击等,南向接口虚假流表注入、协议漏洞利用等,北向接口应用程序漏洞、身份认证问题等,以及数据平面流量劫持、分布式拒绝服务攻击等。提出相应的安全防御机制,为构建安全可靠的基于SDN的通信网络提供理论依据与实践指导。The application of Software Defined Network(SDN)in communication networks is becoming increasingly widespread.However,its centralized control architecture brings new security challenges.This paper thoroughly analyzes the security threats faced by communication networks under the SDN architecture,including single-point failures of the controller,denial-of-service attacks,etc.,false flow table injection through the southbound interface,exploitation of protocol vulnerabilities,etc.,application vulnerabilities and identity authentication problems of the northbound interface,as well as traffic hijacking in the data plane,distributed denial-of-service attacks,etc.Corresponding security defense mechanisms are proposed to provide theoretical basis and practical guidance for constructing a secure and reliable communication network based on SDN.
