Security in the Cloud Computing: A Review

Nowadays, cloud computing has been a focus of research. Security and privacy are the key issues for cloud computing applications, and still face some enormous challenges. In order to facilitate this emerging domain, we firstly in brief review the characteristics, delivery models and deployment models of cloud computing, and then pay attention to the security based on above characteristics and models. By means of deeply analyzing the security challenges, the current security technologies and research status are given. On the basis of these, we raise a propose solution from three aspects: enterprise users, cloud operators and regulators, and deeply illustrate that any one of the three should adopt the corresponding technologies to promote the application of cloud computing.
