Abstract:

SDN network realizes the separation of control and forwarding, and meets the requirements of computing and storage that change continuous, so it is widely used in new technologies in recent years. With the continuous development and deployment of SDN network, it faces more and more security threats and risks. SDN security has become an important research direction in the field of network security. This paper starts with the SDN three-tier architecture, analyzes and summarizes the main security problems faced by the SDN network, discusses the current main measures for security problems, mainly introduces the research results of DDoS attack prevention, and looks forward to the next research direction.

Key words: software defined network, centralized control, security risk, countermeasures, distributed denial of service
