Research on Cyberspace Security System Based on Cloud Computing Environment

The scale of the cloud computing market is increasing year by year, and the security issues it faces are also getting more and more attention. In the cloud computing environment, if the network isolation mechanism fails, malicious tenants will break the border and initiate illegal access, which will expose the cloud's data assets and privacy to huge security risks. Based on the comparative analysis of this paper, the relevant concepts of cyberspace security are analysed, and the “3 + 2” research architecture of cyberspace security is proposed, and related security theories and method support technologies are discussed. On this basis, the key technologies involved are elaborated, and it is concluded that high-performance cloud computing provides important technical support for information security emergency systems with powerful data processing capabilities.
