Cloud computing is a huge system, and its size and complexity determine the difficulty degree to solve cloud computing security problems. Security management of cloud platforms is a complex combination of technology, regulations and behavior. The overall connectivity of the cloud computing environment and the integrity of the data at all levels need to take into account the typical characteristics of the network, systems, applications, users and other factors, and the solutions can be combined and integrated to protect the security of the cloud platform. This paper focuses on the cloud computing virtualization platform, researches on the security baseline configuration and verification method based on cloud computing virtualization platform, and designs the cloud platform security baseline automatic verification technology. On this basis, the security management method for cloud platform component security baseline configuration is proposed to reduce the security risks caused by improper configuration of components in the cloud computing virtualization platform and ensure the safe and stable operation of the cloud platform system.
