Data Security in Cloud Computing

Abstract

Cloud computing is a model which enables widespread access to a shared pool of resources including the characteristics of scalability, virtualization and many others. The most important service offered by cloud is storage wherein the users store the required data. Security is a concern here as the data is stored on remote server with multi user capabilities. The data is at the risk of unauthorized access thereby reducing reliability and privacy. The key issue in cloud regarding security is the openness of the host or service providers. A gateway to the hacker is being provided when a test environment is set on a cloud. Cloud allows exchange of information among its services which requires standards. This development of standards is tough due to the interoperability issues. An intruder can provide malicious threat to the cloud data. The developments of standards are still a concern in security of the cloud. Though there is increasing research done to enhance the security, new issue arises, or the security method becomes inappropriate for the scalable services. Program clustering and slicing for user efficiencies is difficult for the same reason.
