ANSI INCITS 499

Abstract

NGAC follows an attribute-based construction in which characteristics or properties are used to describe and manage policy and to control access to resources. The family of NGAC standards specifies the architecture, functions, operations, and interfaces necessary to ensure their realization in different types of implementation environments at a range of scalability levels. This standard contains an abstract functional description of the NGAC architecture, and also provides an overview of the other standards within the NGAC family of standards. The description herein is abstract because it excludes irrelevant details, and is functional because it partitions the entities comprising the architecture purely on the basis of their function and excludes all other constraints.
