Title GridTrust - A Usage Control Based Trust and Security Framework for Service-Based Grids
Contributors
Abstract Grids have introduced a new model for distributed computing where complex computing problems are solved using a dynamic pool of dispersed commodity-based resources. Grids have the potential to provide scalable and low cost computing and storage. Next Generation Grids will push the model even further by incorporating the service oriented paradigm, thus allowing Grids to provide scalable and low cost service based infrastructures for both business and scientific purposes. From the security point of view, Grids have introduced important challenges because the pool of resources and users are dynamic and managed by different administrative domains: Grid systems are open and dynamic. Current access control technology in Grids only provides coarse grained security: once a user has access to a resource he can do anything he wants with it. The GridTrust consortium argues that coarse grained access control leaves Grids inherently vulnerable, and that not only the access to a resource needs to be controlled, but also the usage that is made of the resource. This chapter describes the GridTrust framework that introduces fine grained and continuous usage control in Grids, and provides the necessary services, tools and methods to deploy it in OGSA compliant Grids.
