A Study of Security Threats and Issues in Cloud Computing

Cloud computing is an emerging technology gaining popularity in IT industry. In a cloud computing environment, the entire data is distributed over a set of networked resources so as data is accessible through virtual machines. Cloud computing offers potential advantages and provides many enterprise applications. With different cloud deployment models available data are migrating from public to private or hybrid cloud. There are various concerns that need to be addressed with respect to security and privacy in a cloud computing environment. In this paper we have analyzed various security risks and threats in cloud computing environment. The paper also presents various schemes and approaches available to mitigate the security challenges and ensure data security, confidentiality, privacy and availability in cloud environment.
