With the development of cloud computing technology, cloud services have been used by more and more traditional applications and products because of their unique advantages such as virtualization, high scalability and universality. In the cloud computing environment, computer networks often encounter security problems such as external attacks, hidden dangers in the network and hidden dangers in information sharing. The network security level protection system is the basic system of national network security work, which is the fundamental guarantee for promoting the healthy development of informatization and safeguarding national security, social order and public interests. This paper studies cloud computing security from the perspective of level protection, combining with the characteristics of cloud computing security. This scheme is not only an extension of information system level protection, but also a study of cloud computing security, aiming at cloud computing security control from the perspective of level protection.
