Authorization, Authentication, Data Access, Grid
As more resources are being made available over the Grid, authorization framework is increasingly becoming vital. The level of information returned needs to be based upon the privileges provided to the user. A few probable authorization frameworks that could be used over the Grid exist. The authorization framework in the Data Portal is built similar to the VOMS approach. The issue of authorization is addressed by creating a digital certificate based authorization infrastructure at the resource provider's end that is managed and controlled at the resource provider's organization. This article discusses the probable authorization frameworks and defines the authorization framework that is being implemented for the Data Portal based upon the requirements from the various ongoing projects.
