Cloud Computing has been envisioned as the next generation architecture of IT Enterprise. In contrast to traditional solutions, Cloud Computing moves the application software and databases to the large data centers. Data security for such a cloud service includes secure channels, access controls, and encryption. When the authors consider the security of data in a cloud, they must consider: confidentiality, integrity, and availability. This paper is concerned with discovery of the vulnerabilities in the landscape of clouds, discovery of security solutions, and. also investigate how the contexts provided by formal and informal institutions affect privacy and security issues in the cloud.
