Cloud Security Solution Based on Software Denned Network

摘要

With the rapid development of cloud computing, the Internet of 'filings, mobile Internet, big data, and smart cities, enterprise data centers are becoming more and more complex. How to protect information security in the era of Internet big data has become a hot topic in various fields. By analyzing the software-defined network and related technologies, a cloud security solution model based on software-defined network is proposed. The three levels of the reference model and the security service framework are described in detail. The model mobilizes the components of the entire security system to synergize in a software-defined manner according to demand. It can not only adapt to the flexible and flexible environment of cloud computing, but also enhance the security and reliability of the network. At the same time, a more granular classification management of network applications has been implemented, providing cloud users with on-demand, accurate, and reliable security service capabilities.
