![ROLE BASED ACCESS CONTROL (RBAC)
AND ROLE BASED SECURITY
One of the most challenging problems in managing large
networks is the complexity of security administration. Role
based access control (also called role based security), as
formalized in 1992 by David Ferraiolo and Rick Kuhn (pdf), has
become the predominant model for advanced access control
because it reduces this cost. A variety of IT vendors, including
IBM, Sybase, Secure Computing, and Siemens began developing
products based on this model in 1994. In 2000, the Ferraiolo-
Kuhn model was integrated with the framework of Sandhu et al.
(pdf) to create a unified model for RBAC, published as the
NIST RBAC model (Sandhu, Ferraiolo, and Kuhn, 2000 - pdf)
and adopted as an ANSI/INCITS standard in 2004. Today, most
information technology vendors have incorporated RBAC into
their product lines, and the technology is finding applications in
areas ranging from health care to defense, in addition to the
mainstream commerce systems for which it was designed. As of
2010, the majority of users in enterprises of 500 or more are
now using RBAC, according to the Research Triangle Institute.

ABAC Workshop, was held July 17, 2013.
Economic Benefits of Role Based Access Control Analyzes
economic value of RBAC for the enterprise and for the national
economy, and provides quantitative economic benefits of
RBAC per employee for adopting firms. Of particular interest
to firms considering RBAC, report calculates savings from
reduced employee downtime, more efficient provisioning, and
more efficient access control policy administration, beyond the
added security provided by RBAC. NIST's RBAC research was
estimated to have contributed $1.1 billion in economic value.

HTML </div> Back to Top Detailed Overview Security administration can be costly and prone to error because administrators usually specify access control lists for each user on the system individually. With RBAC, security is managed at a level that corresponds closely to the organization's structure. Each user is assigned one or more roles, and each role is assigned one or more privileges that are permitted to users in that role. Security administration with RBAC consists of determining the operations that must be executed by persons in
- 9. particular jobs, and assigning employees to the proper roles. Complexities introduced by mutually exclusive roles or role hierarchies are handled by the RBAC software, making security administration easier. This web site explains RBAC concepts, costs vs.benefits and economic impact of RBAC, design and implementation issues, the proposed standard, and advanced research topics. The NIST model for RBAC was adopted as an American National Standard by the American National Standards Institute, International Committee for Information Technology Standards (ANSI/INCITS) on February 11, 2004.
