Gerência de Identidades Federadas em Nuvens: Enfoque na Utilização de Soluções Abertas

Abstract

Cloud computing emerges as a new paradigm for the offering of services in the Web. The main idea is to transfer most of the processing and storage of user applications to a remote cloud of services. Although this approach leads to new business opportunities, the issue of security is still an open and difficult to solve problem. This is because in a cloud there are several applications available as services, many of which have their own access control systems. Furthermore, applications that support service compositions across distinct domains require authentication mechanisms that take into account this collaborative nature. This short course addresses the offering of federated services under an Identity Management perspective. The main concepts related to this subject are introduced in the context of cloud computing as well as the main solutions employed in open federated cloud environments. Finally, a case study in a field of networked robotics that uses one of the solutions discussed in this short course is presented.
