Title

Attribute Reassignment — Regrading Mechanisms

Control

Change security and privacy attributes associated with information only via regrading mechanisms validated using [Assignment: organization-defined techniques or procedures].

Discussion

A regrading mechanism is a trusted process authorized to re-classify and re-label data in accordance with a defined policy exception. Validated regrading mechanisms are used by organizations to provide the requisite levels of assurance for attribute reassignment activities. The validation is facilitated by ensuring that regrading mechanisms are single purpose and of limited function. Since security and privacy attribute changes can directly affect policy enforcement actions, implementing trustworthy regrading mechanisms is necessary to help ensure that such mechanisms perform in a consistent and correct mode of operation.

Parameters

ac-16.9_prm_1: organization-defined techniques or procedures
ac-16.09_odp.01: techniques or procedures
