Security Issues In Cloud Computing And Associated Alleviation Approaches

Cloud computing is the fruit of recent developments in information technology, it provides access to many online services as well as remote computing resources as needed. To be more specific, cloud computing stands today as a satisfactory answer to the problem of storage and computing of data encountered by companies. It provides treatment and accommodation of their digital information via a fully outsourced infrastructure. The latter enables users to benefit from many online services without worrying about the technical aspects of their use. In the meanwhile, it limits costs generated by the management of these data. However, this advanced technology has immediately highlighted many serious security troubles. The major issue that prevents many companies to migrate to the cloud is the security of sensitive data hosted in the provider. Actually, the security problem related to this technology has slowed their expansion and restricted in a severe way their scope. The work in this paper deals to present a literature review of data security approaches for cloud computing, and evaluates them in terms of how well they support critical security services and what level of adaptation they achieve.
