State-of-the-art Survey on Cloud Computing Security Challenges, Approaches and Solutions

The evolution of cloud computing has revolutionized how the computing is abstracted and utilized on remote third party infras- tructure. It is now feasible to try out novel ideas over the cloud with no or very low initial cost. Cloud computing is attractive to companies and organizations as it eliminates the requirement for them to plan ahead for provisioning, and allows them to start with small resources and increase gradually as the service demand rises. There are challenges in adopting cloud computing; but with obstacles, we have opportunities for research in several aspects of cloud computing. One of the main issue is the data security and privacy of information stored and processed at the cloud service provider's systems. In this work, We surveyed several research work on cloud computing related to security challenges and privacy issues. The primary goal of this paper is to provide a better understanding of the security challenges of cloud computing and identify approaches and solutions which have been proposed and adopted by the cloud service industry.
