Securing Data in Cloud

Saumya Kumar

Cloud computing as new technique has developed rapidly in recent time. The problems of security of data over cloud however have caused an enormous impact on the development of cloud and it has also impacted in its popularization, but the importance of cloud and its criticality should not be overlooked. This paper deals with the introduction of cloud computing and different security situation, and it also deal in details about the ways to protect the data and also about the approaches which are being used worldwide to get the maximum protection of data by reducing various risks and threats. Data which are available in the cloud is very much of importance for many applications but it also at the same time poses many risks by the data exposed to applications already having different loophole in its security. Same way, the use of virtualization might add some risk to the data when guest OS is running on top of a hypervisor having no knowledge about the reliability of the running guest OS that might be having security loophole. This paper will too give knowledge on information security perspectives for static data (Data-at-Rest) and Transiting data, and this is based on different level of PaaS, SaaS and IaaS. At last in the paper try to come up with the framework for the cloud computing which can be used effectively for solving the cloud security related problems.
