Toward trustworthy clouds' internet scale critical infrastructure

Abstract

Cloud computing is a new concept using old technologies that has emerged from industry to academia. This result in some confusion about Cloud potential capabilities by overestimating some features and underestimating the challenges, which we attempt to clarify in this paper. We present an overview of Cloud critical infrastructure focusing on what is known as IaaS (Infrastructure as a Service) Cloud type. We then discuss security challenges and requirements, which would hopefully contribute in moving current Cloud untrusted infrastructure to a trustworthy Internet-scale Cloud critical infrastructure. We are mainly focusing on: (a.) Cloud resource management for virtual infrastructure, (b.) security threats from Cloud insiders, (c.) Cloud user-centric security model, and (d.) Cloud infrastructure self-managed services. We have just start working on these areas as part of EU funded TCloud project. © 2011 Springer-Verlag Berlin Heidelberg.
