New Framework for Dynamic Policy Management in Grid Environments

In a multi-organization environment like the GRID, each institute might want to implement limits on how its resources are being used by other institutes. The problem in most traditional policy frameworks lies in the fact that it concentrates on the policy management inside the VO rather than on the management between multiple VOs. The external users, who want to utilize resources in the GRID, ask for guarantees for their jobs and data which most recent policy frameworks do not take into consideration. To date, not enough attention has been paid to policies that deal with such concerns since most existing Grid systems have supported only limited types of policies. This paper introduces a new dynamic framework that supports the management of security policies within the VOs along with the support for the data policies with addressing external users' policies when making decisions.
