Abstract: Cloud computing is considered to be the fourth IT revolution after large computers, personal computers, and the Internet. Cloud computing technology provides flexible and scalable computing capabilities for many new technologies and applications such as big data, Internet of Things, industrial Internet of things, and AI artificial intelligence. Compared with traditional information systems, cloud computing has its own characteristics and particularities, and it will bring some new security risks and problems. How to ensure cloud computing security has become a difficult problem for security personnel. This paper analyzes the security risks faced by cloud computing at this stage, analyzes the current mature cloud security models at home and abroad, and finally designs a technical architecture to ensure cloud computing security for cloud security related personnel.

Key words: cloud computing, cloud security risk, cybersecurity classified protection, cloud computing security model, cloud computing security architecture
