Generalized role-based access control
Proceedings 21st International Conference on Distributed Computing Systems, 2002Generalized Role-Based Access Control (GRBAC) is a new paradigm for creating and maintaining rich access control policies. GRBAC leverages and extends the power of traditional role based access control (RBAC) by incorporating subject roles, object roles and environment roles into access control decisions.

Role-based access control (RBAC) models have been introduced by several groups of researchers. We first introduce the basic components of the American National Standards Institute (ANSI) RBAC model and the role graph model; then we contrast some of the details of these two models.

Role-Based Access Control, we discuss the principles of role-based access control. Two security extensions of the generic UML language—SecureUML and UMLsec—are considered to show various RBAC concerns and application principles. Based on the RBAC domain, a set of transformation rules are defined to link both approaches together and to support the ...

Abstracts The basic concept of role-based access control (RBAC) is that permissions are associated with roles, and users are made members of appropriate roles, thereby acquiring the roles' permissions. This idea has been around since the advent of multi-user computing.
