id: "AC-04(13)" title: "Decomposition into Policy-relevant Subcomponents" family: "AC" family_name: "Access Control" sort_id: "ac-04.13" priority: "P1" implementation_level: "system" parent: "AC-04" enhancement: True
Statement
When transferring information between different security domains, decompose information into {{ insert: param, ac-04.13_odp }} for submission to policy enforcement mechanisms.
Guidance
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.
Assessment Objective
when transferring information between different security domains, information is decomposed into {{ insert: param, ac-04.13_odp }} for submission to policy enforcement mechanisms.
