Guidelines for Access Control System Evaluation Metrics (NIST)
Nearly all applications include some form of access control (AC). AC is concerned with determining the allowed activities of legitimate users, mediating every attempt by a user to access a resource in the system. AC systems come with a wide variety of features and administrative capabilities, and their operational impact can be significant. In particular, this impact can pertain to administrative and user productivity, as well as to the organization’s ability to perform its mission. Therefore, it is reasonable to use quality metrics to verify the mechanical properties of AC systems. This document discusses the administration, enforcement, performance, and support properties of AC mechanisms that are embedded in each AC system. Because of the rigorous nature of the metrics and the knowledge needed to gather them, these metrics are intended to be used by AC experts who are evaluating the highest security AC systems.
