A Review on Different Security Issues and Challenges in Cloud Computing

In computer's world these days cloud computing plays very important role. It gives user facilities like group of things such as software, platform and infrastructure services. Virtualization is the backbone of cloud resource sharing. Security is also a main problem of cloud. Multiple users have their own perception related to the cloud. By using cloud computing, user can access resources anywhere by using internet. So this technique is very useful in user's daily life. One of the factors for cloud computing is cloud services which were provided by the cloud (IAAS, PAAS, and SAAS). These services enable users to access infrastructure, platform and software. Even resources are allocated to users according to their requirements. But many people think it is unsafe to use cloud resources and its services. It is unsafe to use cloud because there is no guarantee of information which is controlled or maintained by the vendors. There are some security issues that are noticed in cloud computing. In this paper, we have discussed a few issues with cloud computing and the challenges of cloud computing. This paper gives overall investigation of security on data, protection and issues in the cloud. The paper also defines the literature review related to the cloud computing issues and threats and also the various security concerns are discussed.
