By embracing the cloud computing paradigm for storing and processing electronic medical records (EMRs), modern healthcare providers are able to realise significant cost savings. However, relinquishing control of sensitive medical data by delegating their storage and processing to third-party cloud providers naturally raises significant security concerns. One way to alleviate these concerns is to devise...
Enterprises increasingly recognize the compelling economic and operational benefits from virtualizing and pooling IT resources in the cloud. Nevertheless, the significant and valuable transformation of organizations that adopt cloud computing is accompanied by a number of security threats that should be considered. In this paper, we outline significant security challenges presented when migrating...
Some of the most valuable business benefits that accompany the cloud adoption cannot be exploited without addressing, first, new data security challenges posed by cloud computing distributed nature. A promising approach for alleviating these risks is to provide a security-by-design framework that will assist cloud application developers in defining appropriate context-driven policies that enhance...
With the pervasion of cloud computing new security risks are created. A promising approach to alleviating these risks is to provide a security-by-design framework that will assist cloud application developers in defining appropriate context-driven access control policies. This paper surveys different approaches to context-driven access control, as well as different modelling formalisms for representing...
With the pervasion of cloud computing, enterprises increasingly rely on ecosystems of distributed, task-oriented, modular, and collaborative cloud services. In order to effectively manage the complexity inherent in such ecosystems, enterprises are anticipated to depend upon brokerage mechanisms for performing policy-based governance and for recommending optimal services to consumers. Such mechanisms...
