	Define RBAC - Role Based Access Control
		Meaning of RBAC - "Role Based Access Control", is used to control a user's access to files or other resources based on their roles in the organization.
		With RBAC, roles can be hierarchical so that if an employee is assigned access as an manager of the advertising department, he will be assigned roles as a member of the advertising department and as an employee.
		RBAC can be used to set up permissions for the operator to carry out this task, which normally requires superuser authority.

	RBAC, Inc. - Management Decision Support Systems (Site not responding. Last check: 2007-10-10)
		As a result of this assessment, the firm requested that RBAC, Inc. work with Ventana Systems to develop an enterprise wide work flow model of the company's operations and to use this model to discover the most important cost and schedule drivers so that management could focus attention on the areas of greatest potential improvement.
		Over the next year, RBAC, Inc. and LSI worked together to produce a first version of the system, known as GRIDNET+, to be used for planning gas sourcing and routing.
		The idea was to design a decision support system which could be used to select among a whole set of possible projects those which should go forward and to schedule them to maximize expected future profitability given a set of resource constraints and risk tolerance.

	RBAC
		RBAC is policy neutral in itself and nicely facilitates the application of the organisation's policy.
		With the concepts of role hierarchy[?] and constraints[?], one can control RBAC to create or simulate Lattice-Based Access Control LBAC[?].
		Thus RBAC can be considered a superset of LBAC.

	RBAC
		RBAC mechanisms can be used by a system administrator in enforcing a policy of separation of duties.
		From the perspective of RBAC, it is therefore important to distinguish the concept and scope of a role for access control purposes as opposed to the more general organizational context in which roles arise.
		However, RBAC has potentially even greater benefit if it can be applied at the level of abstract application-oriented operations such as credit and debit operations on an account.

	[No title]
		RBAC is appropriate for consideration in systems that process unclassified but sensitive information, as well as those that process classified information.
		The RBAC framework provides administrators with the capability to regulate who can perform what actions, when, from where, in what order, and in some cases under what relational circumstances: þ only those operations that need to be performed by members of a role are granted to the role.
		For distributed systems, RBAC administrator responsibilities can be divided among central and local protection domains; that is, central protection policies can be defined at an enterprise level while leaving protection issues that are of local concern at the organizational unit level.

	Role Based Access Control for the World Wide Web
		The principal motivation behind RBAC is the desire to specify and enforce enterprise-specific security policies in a way that maps naturally to an organization's structure.
		Once the RBAC framework is established for the organization, the principal administrative actions are the granting and revoking of users into and out of roles as job assignments dictate.
		Once the choice is made, the RBAC session is established with all authorized roles (i.e., assigned roles along with all roles which the assigned roles inherit) being placed in the ARS.

	Role-Based Access Control (RBAC): Features and Motivations
		The principal motivations behind RBAC are the ability to articulate and enforce enterprise-specific security policies and to streamline the typically burdensome process of security management.
		Although RBAC does not promote any one protection policy, it has been shown to support several well-known security principles and policies that are important to commercial and government enterprises that process unclassified but sensitive information[2][8][9].
		RBAC policies are described in terms of users, subjects, roles, role hierarchies, operations, and protected objects.

	BigAdmin Submitted Article: Custom Roles Using RBAC in the Solaris OS
		Simply defined, RBAC is a security tool to allow any non-root users access to complete tasks, scripts, and so on, with superuser privileges.
		The intended purpose of this document is to provide a cookbook to give any system administrator a quick example of how RBAC is used in the industry, along with a very basic understanding of the features and inner workings of RBAC itself.
		I jump right into the creation and configuration of RBAC roles without providing too much detail on what each file is. I assume the reader will pick up on that stuff as they read ahead.

	Role-Based Access Control - Wikipedia, the free encyclopedia
		Since users are not assigned permissions directly, but only acquire them through their role (or roles), management of individual user rights becomes a matter of simply assigning the appropriate roles to the user, which simplifies common operations such as adding a user, or changing a user's department.
		RBAC differs from access control lists (ACLs) used in traditional discretionary access control systems in that it assigns permissions to specific operations with meaning in the organization, rather than to low level data objects.
		In an RBAC based system an operation might be to create a 'credit account' transaction in a financial application or to populate a 'blood sugar level test' record in a medical application.

	danwalsh: Roles Based Access Control (RBAC)
		The idea of SELinux RBAC is to define a role say auditadm_r which defines all the applications/files that a user in the role can run/manage.
		A user would log in as one of the default user roles and then when they wanted to administrate the audit programs they would have to change their roles.
		MLS use of RBAC goal is not necessarily to stop a malicious admin from getting around these controls, but more to make them understand the role and stop them from making mistakes.

		The primary difference seperating RBAC from other "group" based authorization schemes is that RBAC supports the separation of duties, as discussed in the RBAC paper.
		In diagram one, the subject "Bob" attempts to access the object "program." The program then contacts the RBAC Server via the REST api to verify that bob is allowed to use the program.
		The RBAC server authenticates the program and then determines Bob's available transactions on the program using its datastore (db) and internal logic.

	What is Role-based access control (RBAC)? - a definition from Whatis.com - see also: RBAC (via CobWeb/3.1 ... (Site not responding. Last check: 2007-10-10)
		Role-based access control (RBAC) is a method of regulating access to computer or network resources based on the roles of individual users within an enterprise.
		When properly implemented, RBAC enables users to carry out a wide range of authorized tasks by dynamically regulating their actions according to flexible functions, relationships, and constraints.
		In RBAC, roles can be easily created, changed, or discontinued as the needs of the enterprise evolve, without having to individually update the privileges for every user.

	RBAC configuration
		Although roles could be implemented directly using TE domains, this policy provides an additional layer of abstraction for grouping TE domains into roles and for expressing a role hierarchy.
		The RBAC configuration contains four kinds of statements: role declarations, role transition rules, role allow rules, and role dominance definitions.
		A role declaration specifies a name for the role and a set of types that may be associated with that role.
