Role security access control of the distributed object systems

Abstract

The paper shows how role-based access control (RBAC) models can be implemented in distributed object-based systems that follow OMG/ORB standards. The paper introduces a novel approach that provides for automatic role activation by the security components of the middleware, which brings role-based access control to security-unaware applications. Role-based access control has been being recognized as an integration to traditional discretionary and mandatory access control models.
