RESUMO

The term computational grid refers to a class of distributed systems that allows for the association and integration of multiple independent domains in virtual organizations. A coherent access control services in such a system should be flexible to integrate multiple polices so as to permit administrators, sites, and users to determine roles and mechanisms to protect their resources. This thesis introduces the GridMultiPolicy, a flexible system that manages and integrates multiple policies and mechanisms to enforce access control in grid environments. Additionally, policies have been developed to show how the proposed system is able to offer answers to security needs present in grid use scenarios. The impact of the GridMultiPolicy and the developed policies was evaluated by performance tests. Key-words: Computational grid. Grid. Distribuited system. Virtual organization. Policy and security for virtual organization. GridMultiPolicy.
