Information Security in Cloud Computing: A systematic Literature Review and Analysis

Cloud computing is an evolutionary outgrowth of prior computing approaches which build upon existing and new technologies. Cloud computing is a model for on demand network access to a shared pool of resources such as servers, storage, applications and related services. Cloud computing can be provisioned and released with minimum interaction and preferably without intervention of cloud service provider. The rising awareness and implementations of cloud services and its underlying technologies cause the need for security requirements being up to date. These developments have created new security vulnerabilities, including security issues whose full impressions are still rising. This paper presents an overview and study of cloud computing, with several security threats, security issues, currently used cloud technologies and countermeasures. The security challenges in cloud computing are formidable, especially for public clouds whose infrastructure and computational resources are owned by an outside party that sells those services to the general public. Cloud security requirements have been addressed in publications earlier, but it is still difficult to estimate what kinds of requirements have been researched most, and which are still under-researched. This paper carries out a systematic literature review by identifying cloud computing security requirements from publications. Along with security issues, upside of information security in cloud computing has also been part of this work.
