Uma Avaliação Comparativa dos Mecanismos de Segurança nas Ferramentas OpenStack, OpenNebula e CloudStack

Abstract

The IaaS service model is gaining attention due its importance to the cloud computing environment, it is responsible for simplifying the access and the management of high-end processing and storage systems, besides being the base that allows the outsourcing of upper layers, PaaS and Saas. The IaaS cloud tools are responsible for controlling the virtual infrastructure as well the environment security, which is an important characteristic for cloud applications, once the system can be integrated with public clouds through the Internet. In this paper, the goals are evaluate and compare the security layer, from the administrator point of view, of three open source IaaS tools: OpenStack, OpenNebula and Cloudstack. Considering the security layer from Dukaric taxonomy, the results shown that all the tools have a equivalent security level, however, there are evidence that not all the security features found in the tools fits in the taxonomy description.
