The operating system, when transferring information between different security domains, must decompose information into policy-relevant subcomponents for submission to policy enforcement mechanisms.

Overview

Finding ID	Version	Rule ID	IA Controls	Severity
RHEL-06-000394-PF	RHEL-06-000394-PF	RHEL-06-000394-PF_rule		Medium

Description
Information flow control regulates where information is allowed to travel within an information system and between information systems (as opposed to who is allowed to access the information) and without explicit regard to subsequent accesses to that information. Policy enforcement mechanisms include the filtering and/or sanitization rules that are applied to information prior to transfer to a different security domain. Parsing transfer files facilitates policy decisions on source, destination, certificates, classification, subject, attachments, and other information security-related component differentiators. Policy rules for cross domain transfers include, limitations on embedding components/information types within other components/information types, prohibiting more than two-levels of embedding, and prohibiting the transfer of archived information types.

Check Text ( C-RHEL-06-000394-PF_chk )
This is a permanent finding.

Fix Text (F-RHEL-06-000394-PF_fix)
This requirement is a permanent finding and cannot be fixed. An appropriate mitigation for the system must be implemented but this finding cannot be considered fixed.
