Cyber Security Threats in Cloud: Literature Review

In recent years, data has been expanding every second in terms of velocity, volume, and variety. This has resulted in enormous and complex big data, raising challenges in the storage, management, analysis of these big data and security thereof. Many organizations tend to use cloud systems in order to facilitate the operation in big data without being fully aware of the security and privacy challenges that the utilization of these systems pose and consequently ignoring the important practices and techniques that should be implemented when using cloud systems. These security threats therefore require more research in order to produce solutions to the cloud system environment. The goal of this paper is collection of most common cyber security threats in the cloud system environment and most common used mitigation techniques by reviewing the published papers in the period from 2019 to 2020 followed by cloud risk assessment case study in an organization in Saudi Arabia.
