Role-based access control models
Computer, 1996Security administration of large systems is complex, but it can be simplified by a role-based access control approach. This article explains why RBAC is receiving renewed attention as a method of security administration and review, describes a framework of four reference models developed to better understand RBAC and categorizes different ...

Role-Based Access Control and the Access Control Matrix
ACM SIGOPS Operating Systems Review, 2001The Access Matrix is a useful model for understanding the behaviour and properties of access control systems. While the matrix is rarely implemented, access control in real systems is usually based on access control mechanisms, such as access control lists or capabilities, that have clear relationships with the matrix model.

Privacy-aware role based access control
Proceedings of the 12th ACM symposium on Access control models and technologies, 2007In this article, we introduce a comprehensive framework supporting a privacy-aware access control mechanism, that is, a mechanism tailored to enforce access control to data containing personally identifiable information and, as such, privacy sensitive.

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.

Administration in role-based access control
Proceedings of the 2nd ACM symposium on Information, computer and communications security, 2007Administration of large-scale RBAC systems is a challenging open problem. We propose a principled approach in designing and analyzing administrative models for RBAC. We identify six design requirements for administrative models of RBAC. These design requirements are motivated by three principles for designing security mechanisms: (1) flexibility and ...

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.

Practical Role-Based Access Control
Information Security Journal: A Global Perspective, 2009This article presents access control from a general and a role-based perspective. The article's focus is role based Access Control from a practical vice a theoretical perspective. The article starts with some access control definitions and two secure access control models.
