Advancement in the field of technology have given rise to popularity and growth of cloud computing. As a new
paradigm of computing, cloud computing has emerged to change the old ways of computing. The diversity of services delivered
through cloud computing model increases their vulnerability to security attacks and incidents. So, the security problem of cloud
is very important as it can prevent the rapid development of cloud computing. The main objective of this paper is to highlight the
concept of cloud computing and its security risks and challenges. In this paper, we provide an inclusive review of existing
security and privacy issues in cloud computing. This paper also surveys the recent research related to cloud security and existing
solutions provided in this regard.
