Abstract
Cloud computing is a set of available services and resources available through the internet. Basically it can be considered as a virtual pool for computing and sharing such as software infrastructures, applications, and business processes. As this field of technology has seen a rapid growth in recent times, security has been the major concern. Confidentiality, Integrity, Availability, Authenticity and Privacy are essential concerns for both Cloud providers and consumers as well. This paper provides a concise but all-round analysis on data security and privacy protection issues associated with cloud computing.
