Service Level Agreement (SLA) is an essential tool for managing cloud computing services. The support of the security requirements through SLA is fundamental to achieve the full potential of the cloud computing paradigm. In this paper we present how security requirements are addressed in a cloud computing SLA. Furthermore, a unified SLA lifecycle for cloud computing services is proposed. The relationship...
The advent of e-Science and Big Data applications brought the need of working with increasingly larger datasets as well as the demand of collaboration and resource distribution among research institutions. This work presents the experience of six Brazilian institutions in implementing the Science DMZ for supporting e-Science networking, including the proposed architecture, equipment specification...
The discussion of alternatives to the Internet architecture has been the subject of research for several years, resulting in a number of solutions and mechanisms that can help even the current approach. Within this context, the paradigm of Software Defined Networking (SDN) is becoming popular due to recent initiatives based on OpenFlow. This article presents an analysis of security policy rules applied...
Security is a key concern when adopting cloud technology. Cloud solutions include not only issues inherited from related technologies, such as virtualization and distributed computing, but also new concerns associated to complexity of the cloud ecosystem, composed by the cloud entities and their interactions. One of the concerns is related to authentication and authorization in the cloud in order...
