27、mong government and industry pur-chasers of information technology products for a consistent and uniform definition ofrole based access control (RBAC) features. Vendors were implementing role basedaccess control features in their database management systems, security manage-ment, and network operati

28、ng system products, without general agreement on the def-inition of RBAC features. This lack of a widely accepted model resulted in uncertaintyand confusion about RBACs utility and meaning. This standard seeks to resolve thissituation by using a reference model to define RBAC features and then descr

29、ibingthe functional specifications for those features.This standard contains three annexes. Annexes A and B are informative and are notconsidered part of the standard. Annex C is normative and is considered part of thestandard.Requests for interpretation, suggestions for improvement or addenda, or d

They should be sent to InterNational Committee for InformationTechnology Standards (INCITS), ITI, 1101 K Street, NW, Suite 610, Washington, DC20005.This standard was processed and approved for submittal to ANSI by INCITS.

36、sts of two main parts the RBAC Reference Model and the RBAC System and Administrative Functional Specification. The RBAC Reference Model defines sets of basic RBAC elements (i.e., users, roles, permissions, operations and objects) and relations as types and functions that are included in this standa

37、rd. The RBAC reference model serves two purposes. First, the reference model defines the scope of RBAC features that are included in the standard. This identifies the minimum set of features included in all RBAC systems, aspects of role hierarchies, aspects of static constraint relations, and aspect

38、s of dynamic constraint relations. Second, the reference model provides a precise and consistent language, in terms of element sets and functions for use in defining the functional specification. The RBAC System and Administrative Functional Specification specifies the features that are required of

39、an RBAC system. These features fall into three categories, administrative operations, administrative reviews, and system level functionality. The administrative operations define functions in terms of an administrative interface and an associated set of semantics that provide the capability to creat

40、e, delete and maintain RBAC elements and relations (e.g., to create and delete user role assignments). The administrative review features define functions in terms of an administrative interface and an associated set of semantics that provide the capability to perform query operations on RBAC elemen

41、ts and relations. System level functionality defines features for the creation of user sessions to include role activation/deactivation, the enforcement of constraints on role activation, and for calculation of an access decision. Annex A provides a functional specification overview. Informative Ann

42、ex B provides a rationale for the major RBAC components defined in this document. A companion to this standard describes the enhancement of RBAC constraints. The present standard recognizes only constraints that are local to an RBAC environment. These constraints deal only with separation of duty an

43、d cardinality. These constraints are evaluated within the local RBAC environment, as opposed to being provided from outside the local RBAC environment. The RBAC Policy-Enhanced (RPE) standard RPE also specifies constraints evaluated within the local environment. In addition, external constraints or

44、the results of evaluating external constraints are imported into the environment. These constraints may change in real-time. This standard and the RPE standard have the evaluation of constraints as part of the access control decision in common. Thus, they are compatible, with the base standard INCIT

45、S 359-2012 2 addressing more limited constraints and the RPE standard addressing a potentially wide variety of constraints. 2 CONFORMANCE Not all RBAC features are appropriate for all applications. As such, this standard provides a method of packaging features through the selection of functional com

46、ponents and feature options within a component, beginning with a core set of RBAC features that must be included in all packages. Other components that may be selected in arriving at a relevant package of features pertain to role hierarchies, static constraints (Static Separation of Duty), and dynam

47、ic constraints (Dynamic Separation of Duty). INCITS 459-2011, RBAC Implementation and Interoperability Standard, defines acceptable combinations of RBAC features. To conform to this standard, an RBAC system shall comply with all of the core set of RBAC functional specifications in 7.1. Conformance o

48、f an RBAC system to any other functional specifications for a particular component and feature option, found in 7.2 through 7.4, is optional and dependent upon the functional requirements of a particular application. 3 NORMATIVE REFERENCES RIIS INCITS 459-2011 Role Based Access Control Implementatio
