Security issues in cloud computing

This paper presents a comprehensive study on the challenges and issues of security in cloud computing. We first look into the impacts of the distinctive characteristics of cloud computing, namely, multi-tenancy, elasticity and third party control, upon the security requirements. Then, we analyze the cloud security requirements in terms of the fundamental issues, i.e., confidentiality, integrity, availability, trust, and audit and compliance. Furthermore, we discuss the taxonomy for security issues in cloud computing. Finally, we summarize the security issues in cloud computing by a cloud security architecture.
