Fine-Grained Authorization for Job Execution in the Grid: Design and Implementation

Title: Fine-Grained Authorization for Job Execution in the Grid: Design and Implementation

Research Question: How can we enable fine-grained authorization for resource usage and management in Grids, allowing virtual organizations to enforce their own policies in addition to those of the resource owners?

Methodology: The researchers proposed a design for service and resource management that enables a virtual organization (VO) and resource managers to specify fine-grained service and resource usage policies using VO credentials and allows resources to enforce those policies. They implemented this design as extensions to the Globus Toolkit version 2 (GT2) resource management mechanism.

Results: The researchers presented a prototype of this implementation, combined with the Akenti authorization system, which was demonstrated at the SC02 conference and is currently being adopted by the National Fusion Collaboratory.

Implications: This research has implications for the field of computational Grids, as it addresses the need for more complex and dynamic authorization policies in a rapidly changing environment. It also contributes to the ongoing development of virtual organization concepts and their management within the Grid computing framework.
