The ALG that is part of a CDS must decompose information into organization-defined, policy-relevant subcomponents for submission to policy enforcement mechanisms before transferring information between different security domains.

SRG-NET-000282-ALG-000071	SRG-NET-000282-ALG-000071	SRG-NET-000282-ALG-000071_rule		Medium

Description
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. Parsing transfer files facilitates policy decisions on source, destination, certificates, classification, attachments, and other security-related component differentiators. Policy enforcement mechanisms include the filtering and/or sanitization rules applied to information before transferring to a different security domain.

If the ALG is not part of a CDS, this is not a finding. Verify the ALG, when transferring information between different security domains, is configured to decompose information into organization-defined, policy-relevant subcomponents for submission to policy enforcement mechanisms before transferring information between different security domains. If the ALG is not configured to decompose information into organization-defined, policy-relevant subcomponents for submission to policy enforcement mechanisms before transferring information between different security domains, this is a finding.
