Security of Cloud Storage: A Survey

Abstract

Cloud computing is gaining increased adoption for everyday computing and storage needs. Its use starts from storing personnel files to storing Government data, enterprise business data, data from IOT devices, satellite imagery data, and data from social media applications running on the cloud and so on. However, due to lack of awareness and appropriate security measures, cloud users become victims of the security vulnerabilities exposed by the cloud storage. The cloud user and Cloud Storage Provider (CSP) should deploy appropriate techniques and follow best practices to overcome the security issues proactively. In this paper, the security vulnerabilities existing in cloud storage are discussed and recent state-of-the-art techniques used to enhance its security are analyzed. Further discussion is carried out on the best practices and security policies framed by various organizations. This survey shall enable researchers to gain an overall picture of cloud storage security aspects and find out open issues that can be further researched. Further, it shall enhance cloud storage providers to adopt stateof-the-art techniques to prevent security incidents. The end-users shall be aware of the risks of cloud storage and demand the appropriate security measures from the CSPs.
