A Study on Cloud Security Issues and Challenges

Cloud computing is one of the today’s most exciting technology because of its cost-reducing associated with computing while increasing flexibility and scalability for computer processes. In the past few years, cloud computing has growing from being a promising business idea to one of the fastest growing parts of the IT industry. Even there are great benefits to be gained from cloud computing, it also enables new categories of threats to be introduced. Many IT companies have expresses concern about critical issues (like security) that exist with the widespread implementation of cloud computing. In rebuilding, considering the facet of cloud as a social infrastructure, security is a critical problem of clouds. Most of insecurity against clouds can be summarized as a social insecurity, which classified into multiple stakeholder problems, the open space security problem, and the mission critical data handling problem. Security, in particular, is one of the most argued issues in cloud computing. Several enterprises look at cloud computing warily because of projected security issues in cloud computing. These threats are a result of the cloud virtual infrastructure complexity created by the adaptation of the virtualization technology. This paper gives a brief introduction to the cloud computing platform and the services it provides. In particular, we discuss some of the key security issues as well as the research challenges to secure cloud.
