AC-04(13) Decomposition into Policy-relevant Subcomponents

NIST SP 800-53 (controls) 5.2.0 against 5.2.0
All changes in this version
unchanged AC part of AC-4

Title

Decomposition into Policy-relevant Subcomponents

Control

When transferring information between different security domains, decompose information into [Assignment: policy-relevant subcomponents] for submission to policy enforcement mechanisms.

Discussion

Decomposing information into policy-relevant subcomponents prior to information transfer facilitates policy decisions on source, destination, certificates, classification, attachments, and other security- or privacy-related component differentiators. Policy enforcement mechanisms apply filtering, inspection, and/or sanitization rules to the policy-relevant subcomponents of information to facilitate flow enforcement prior to transferring such information to different security domains.

Parameters

ac-04.13_odp: policy-relevant subcomponents

Assessment objective

AC-04(13) when transferring information between different security domains, information is decomposed into [Assignment: policy-relevant subcomponents] for submission to policy enforcement mechanisms.
