A Review and Analysis of Cloud Computing Information Security

Cloud computing is a whole new model that offers a non-traditional computing model for IT Industry to accept Information Technology and related functions and aspects without open investment and with lower Cost of Ownership (TCO). The security problem becomes amplified under the cloud model as new dimensions enter into the problem scope related to the architecture, multi-tenancy, layer dependency, and elasticity. This paper introduces a detailed analysis of the cloud security problem. It investigates the problem of security from the cloud architecture perspective, the cloud characteristics perspective, cloud delivery model perspective, and the cloud stakeholder perspective. The paper investigates some of the key research challenges of implementing cloud-aware security solutions which can plausibly secure the ever-changing and dynamic cloud model. Based on this analysis it presents a derived detailed specification of the cloud security problem and key features that should be covered by any proposed security solution for cloud computing.
