RBAC Extension Model for ERP Systems in Multidomain Environments

This paper presents an extension of the Role Based Access Control (RBAC) Model for Enterprise Resource Planning (ERP) systems, developed with the perspective of been deployed in multidomain environments, to provide the possibility of planning the resources of several institutions simultaneously from a single data center. The extension of the model allows to control the access of the users to different resources (system, services, data bases, information, among others), ensuring the compartmentalization of the information. The resulting model was applied in the development of an access control system that centralizes the security of several applications, in which user can access to various entities and fulfill many roles with the possibility of interacting with multiple resources.
