The cloud computing technology provides cost effective, powerful computation resources on the fly. It minimizes the need to procure and maintain expensive hardware, software and reserve space for IT infrastructure. These features for cloud computing encourages organizations and individuals to migrate their resources needs and services to the cloud. However, cloud computing services provided by third-party vendors possesses various security threats. The cloud services store sensitive data (such as credentials, personal information, etc.) of various users on the shared environment that escalates security concerns. The aim of this research survey paper are three-fold: i) provides guideline for researchers who are new to the cloud computing security area, ii) provides the state-of-the-art survey of cloud computing security issues and challenges, and iii) provides the further research directions required into security assurance of the cloud computing.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
