Research on Traffic Monitoring and Security Protection of Cloud Computing Network Based on SDN

Abstract

This paper studies the application of Software Defined Network (SDN) in cloud computing environment, and enhances the security and reliability of cloud platform through network traffic monitoring. This paper designs and constructs a detailed structural model to systematically analyze the key attributes of various security categories, including their names, types, characteristics, security levels, risk levels and weights. Finally, the paper uses a large number of actual data to verify and give the analysis results in the form of charts. The experimental results show that SDN technology can effectively monitor abnormal traffic and respond to security threats in time, and can significantly enhance the security protection capability of cloud computing environment. It also provides a new method and technical solution for the security management of cloud network.
