Cloud Computing Security: A Survey

Cloud computing brings new possibilities for individuals and firms to utilize computing as a utility. It utilizes computing power irrelevant of user’s location and devices. Thus it has become more demanding due to its performance, high computing power, cheapness, elasticity, accessibility, scalability and availability. Cloud computing offers ubiquitous operation with different security challenges. In this paper we discuss security challenges and vulnerabilities as well as limitations of current security modules. This paper will serve as a baseline guide for new researchers in this area.
