The purpose of this study is to examine the state of both cloud computing security in general and OpenStack
in particular. Conducting a reassessment of cloud computing security can provide a greater understanding of
how cloud computing functions and what types of security issues arise therein. This study is divided into
two parts; in the first part, the background of cloud computing and its different deployment models are
discussed. This section also describes various security challenges that affect organizations’ decisions to
adopt cloud computing. In the second part, an overview of the security issues in OpenStack is presented.
