Using the VOM portal to manage policy within Globus Toolkit, Community Authorisation Service & ICENI resources

The emergence of computational and data grids has led to resources within a single organisation being exposed to other users within a ‘virtual organisation’ (VO) that encompasses a dynamic distributed infrastructure. Due to this dynamic nature of VOs, there is a need for an infrastructure to facilitate the management of the constituent users and resources. We have been developing an easy to use and secure management infrastructure the Virtual Organisation Management (VOM) Portal. We present how using the VOM portal, we are able to manage policies within Globus Toolkit, Community Authorisation Service (CAS) and Imperial College e-Science Networked Infrastructure (ICENI) middleware.
