Different Challenges in Energy- Efficient Cloud Security: A Brief Review

Because of its ability to reduce computing costs while enhancing scalability and flexibility for computer services, cloud computing is the trendiest study subject today. Cloud computing is internet-based computing that provides consumers with on-demand services by sharing resources and delivering data to applications. Cloud computing is one of the most rapidly increasing IT trades in the commercial world. Cloud computing security has become a major stumbling block to its growth. Cloud computing security refers to a collection of policies, processes, controls, roles, permissions, and technologies that work together to safeguard cloud-based systems and data. Because cloud users must preserve their data in the cloud, cloud computing security has become a major topic in academic study and industry. Lack of security in the cloud might cause users to lose faith. The topic of this study is a review of cloud computing security. The research takes into account all levels of SaaS (Software as a Service), PaaS (Platform as a Service), and IaaS (Infrastructure as a Service), as well as deployment models (Private, Public, Hybrid, and Community Cloud). The main objective of this paper is to study and understand the existing genetic algorithm and two factor authentication meant cloud computing security and finding the gaps through literature survey.
