Survey: Risk assessment models for cloud computing: Evaluation criteria

One of the most challenging steps in migrating infrastructure or an application to a cloud computing is security threats. Adapting a current risk assessment tool to cloud computing is a very difficult task due to its several characteristics and the use of distributed systems. This work proposes a critical review of the recent proposed risk assessment frameworks and models in cloud computing environments. The aim of this paper is comparing the latest models of risk assessment in cloud computing in order to identify the strengths and weaknesses of each model and propose a list of evaluation criteria to be used while analyzing risk approaches.
