Abstract:

The new service model and virtualization technology inevitably brings a series of new security problems in cloud computing environment. Security has been regarded as one of the most important issues in the development of cloud computing. To study the safety of the public cloud, from the user security objectives data security and cloud service availability and performance, the security threats facing the public cloud was analyzed comprehensively. A public cloud security framework of reference is designed, User management, data security, data center hardware and software security and safety problems caused by the transfer of control are proposed to strengthen public cloud security. Finally, the cloud security evaluation is discussed. Experimental results show that this architecture can improve the safety of the public cloud against all types of security threats.

Key words: public cloud, cloud security, cloud security framework, cloud security evaluation
