摘要：The cloud idea has been percolating to every tangible domain. Having understood the fact that significant savings can be availed and acquired with the assimilation and adoption of cloud concepts, business executives, entrepreneurs and engineers are working overtime in putting cloud-centric tactical as well as strategical plans and proposals in place to easily and quickly accomplish the lingering mantra of more with less. Cloud infrastructures (private, public and hybrid) are erupting across the globe, cloud platforms, applications and services are being developed or assembled, deployed, managed, delivered via one or more of these cloud infrastructure providers. The popularity and pervasiveness of cloud services are quiet surging. Though cloud computing is being seen as a silver bullet for the ICT industry, there are a few shortcomings such as security, availability, data ownership, etc. In this study, we are concentrating on the perpetual and prominent security problem of the cloud paradigm. We have discussed about the possible solutions for the security issues at different layers and levels.
