Discussion on Network Security under SDN Architecture

As a new network architecture, Software-defined network opens a new world for technical innovation and industrial development and provides a scalable and flexible solution for managing complex IoT. With the gradual maturity of SDN technology, the security issue has become the focus of recent academic research and industrial development. This article briefly introduces the SDN architecture and its application in the Internet of Things, aiming to identify structural defects caused by security issues in the system by analyzing the basic framework of SDN, and proposes a simple handling method at the end of the article. That is, focus on the plane security of station reporting control and the security of the north-south interface, limit the scope of security risks, and implement strict authorization and authentication mechanisms.
