On Usage Control for GRID Services

ABSTRACT: In recent years, usage control has been proposed as a novel authorization solution for open, heterogeneous, distributed computer environments. Grid is a such environment providing services for seamless sharing and usage of heterogeneous computational resources. Researches have shown that usage control is a viable solution for authorization in Grid. Unfortunately, the implementation of continues usage control for Grid services is not widely presented. In this paper, we present a usage control model and focus on continuous control over Grid services. If a security policy is violated during a service execution, the service should be blocked or terminated. Our approach presents different levels of granularity and enforces coarse and finegrained usage control on generic and computational Grid services.
