Information is the most precious assets to organizations; hence it is necessary to have mechanisms to protect it and to make it available only to whom have factual permission to use it. Considering the need for protection of the information in organizations it is proposed in this work a system to manage access control policies which can be easily used, that is, it does not require any knowledge of policies codification language. Further, as the creation of new policies could generate conflicts with existent ones, this work also proposes algorithms which manage automatically, in a period of policies creation, the control of some kinds of conflicts, such as interest conflicts. As result, we have offer a Access Control Police Management System that enable that the process of generation and editing policies occurs easily and without conflicts. The reference model used in this work refers to health organizations; however this study can be applied in other fields.
