• Requirement

    When transferring information between different security domains, decompose information into [Assignment: organization-defined 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.
