Abstract:

Cloud network security has become a strong need under the background of the new infrastructure and digital economy, while cloud network integration security has been defined as an ongoing trends.Initially, three major types of problems facing 5G private network users were presented in providing overall security services, and an overall software-defined security architecture in the 5G+ era was proposed.Furthermore, the corresponding prototype system design and implementation was discussed based on this architecture.At the end, the verification shows that the software-defined security orchestration and scheduling system based on the cloud-based architecture helps to accurately solve the overall business security threats and hidden dangers of 5G private network enterprise customers in the 5G+ era, providing systematic reference value for subsequent research.

Key words: software-defined security, service function chain, network function virtualization
