Abstract:

Cloud computing is a new method sharing infrastructure which provides the usage of service,application,information and infrastructure composed of “resource pool”computing,network,information and storage.The features of cloud computing directly impact the security threats of its environment and relative security policies,which include the self-service on demand,broadband access,visualization resource pool,quick elastic architecture,measurable services and multi-tenant.Cloud computing could definitely introduce positive effect because it has multiple benefits from scale economy to application availability.Nowadays,more and more enterprise users are ready to be involved in the cloud circle with the support of cloud computing providers and advocates.However,cloud computing also brings some new security issues.The security problem is very important since a large number of users share the IT infrastructure.In this paper,the specific cloud computing security requirement and solution are analyzed.The current status of international and domestic research and products are presented.

Key words: cloud computing, visualization, security, credibility
