According to a Forbes’ study published in 2015, cloud-based security spending is expected to increase by 42%. To another research, the IT security expenditure had increased to 79.1% by 2015, showing an increase of more than 10% each year. International Data Corporation (IDC) in 2011 showed that 74.6% of enterprise customers ranked security as a major challenge. [1] The objective of our research is to understand the cloud computing advantages and its components, security issues, and risks, along with emerging solutions that may potentially mitigate the vulnerabilities in the cloud. In this paper we think about the big picture of cloud computing security - extending across the potential issues and vulnerabilities associated with software platform; virtualization infrastructure; identity focus and access control; confidentiality and privacy; data integrity; physical and process security views; and legal compliance in cloud. We introduce our conclusions from the considering a matter of a cloud service provider, cloud consumer, and third-party authorities such as Govt. We also deal the threat models and their significance in cloud security in areas such as Information Centric Security, Privacy Preserving Models and Trusted Computing.
