Implement STANAG 4774/4778 label handling across email per RFC 8551 S/MIME + RFC 9580 OpenPGP profiles, documents per OOXML/ODF embedded metadata + PDF/X-3 embedded XML, file storage per NTFS/EXT4 extended attributes + cloud object storage tags. Configure email gateways (Microsoft Exchange + Postfix + Sendmail + Cisco IronPort + Proofpoint + Mimecast) to verify + filter + route based on STANAG labels. Configure document management systems (SharePoint + OpenText + IBM Filenet + Documentum) to enforce label-based access control + retention.
The graph holds this control, the 0 it maps to, and the evidence behind each claim, over MCP and REST.
