Research and Design of Multi Dimension Protection System for Data Security in Cloud Computing Environment

Based on the hierarchical architecture of cloud computing, this paper discusses the confidentiality, integrity and usability of multi-dimensional security system in light of user dimension, dimension, business dimension and basic dimension. According to this division, this paper puts forward specific security technologies and strategies. Through the use and management of the "cloud" of the main (cloud computing users and service providers) and "cloud" implementation environment (network hardware environment and Social system environment) into the cloud security off the system, as much as possible to grasp the cloud computing in the application and promotion process in all aspects of the problem, thus a comprehensive, comprehensive "trusted cloud" system is established. In the discussion of multi-dimensional system model, each dimension of security protection has its own emphasis. By using the trust management technology, the user authentication and authorization system based on trust management are put forward. Data dimension and data encryption technology research, design and implementation of a cloud storage security solutions. Taking service-oriented security audit and monitoring as the focus, this paper puts forward service-oriented cloud security monitoring system. The basic dimension focuses on network and application system host security. In addition, a standardization evaluation system for cloud security is put forward to improve the multi-dimensional protection system for safety standardization.
