Platform to enforce multiple access control policy in grid hosting environment

Computational grid aims to get a better improvement of the existents resources by the use of distributed and flexible systems. However, the utilization of this system brings new challenges in relation to security, requiring an access control service that can be adequate for different conditions of heterogeneous environments and allows its integration with pre existents mechanism. This work presents a flexible platform that integrates multiple policy models to enforce access control in grid hosting environments by controlling the actions of submitted applications. The results of the operational test show how the current platform can realize access control based on IDS systems and enforces a Least Privilege policy model.
