Abstract Cloud computing has gained huge attention over the past decades because of continuously increasing demands. There are several advantages to organizations moving toward cloud-based data storage solutions. These include simplified IT infrastructure and management, remote access from effectively anywhere in the world with a stable Internet connection and the cost efficiencies that cloud computing can bring. The associated security and privacy challenges in cloud require further exploration. Researchers from academia, industry, and standards organizations have provided potential solutions to these challenges in the previously published studies. The narrative review presented in this survey provides cloud security issues and requirements, identified threats, and known vulnerabilities. In fact, this work aims to analyze the different components of cloud computing as well as present security and privacy problems that these systems face. Moreover, this work presents new classification of recent security solutions that exist in this area. Additionally, this survey introduced various types of security threats which are threatening cloud computing services and also discussed open issues and propose future directions. This paper will focus and explore a detailed knowledge about the security challenges that are faced by cloud entities such as cloud service provider, the data owner, and cloud user.

1 Introduction Large rooms and the huge amounts of electricity play an important role in the history of the technology so that they are widely used to get only a little processing output. In the last decades, small and more efficient computers have gradually taken the place of huge (in some cases, room-size) computers. In recent years, the demand * Marjan Kuchaki Rafsanjani [email protected] 1

for data has dramatically raised and the number of online users has increased behind belief. Also, traditional computing infrastructure has become expensive and difficult to be managed so that accessing data has become impossible by traditional computing anywhere and at any time. Therefore, the external storage system has turned out to be a necessity for saving data. That traditional computing is now unable to handle the increased number of online users on networking sites, social networking, multimedia broadcasting, etc. Since global Internet usage has dramatically grown step by step, the volume of the uses and availability of services led to a new concept called cloud computing. Figure 1 indicates the progress that the computing infrastructure and platforms are provisioned
