Gerenciamento Distribuído de Políticas de Controle de Acesso em Ambiente Corporativo

Arlindo L. Marcon JrAltair O. SantinMaicon Stihler

The unified management of user rights and access control policies in corporations with many branches may seem paradoxical. The environmental heterogeneity and branch particularities require decentralized controls, while policy management aims for control unification. This paper proposes a distri- buted architecture for access control with unified management of corporate policies. Starting from rights specified on authorization certificates, corporate branches are autonomous to create and apply policies that will update the corporative repository. The provisioning keeps the policy synchronized on the local branch repository. The prototype using SPKI/SDSI and Web Services shows the proposal's feasibility.
