Description
Summary:Levaraging the convergence of Grid and Web services technologies, we anticipate the emergence of new business and scientific computing paradigms that are based on dynamic Virtual Organisations (VO). These VOs span across organisational boundaries and enable the enactment of collaborative processes that integrate services, resources and knowledge in order to perform tasks that the VO partners could not undertake on their own. Such a dynamic and complex structure opens several challenging problems relating to VO security. In this paper, we summarise a novel architecture supporting Grid-enabled collaboration for the purposes of Application Service Provision. We then focus on the underpinning security architecture that enables the federated management and distributed enforcement of dynamic security perimeters for virtual communities of services, and on resources that span across administrative and enterprise boundaries. We highlight how this architecture, realised in the context of a European research project developing a Grid platform for application serviced provision, addresses the outstanding challenges that underlie the automation of trust and security management in scalable, multi-institutional, and dynamic Virtual Organisations.
