To generate ANSSI-compliant cartography for NIS2, you need a structured four-level mapping covering business processes, application dependencies, infrastructure inventory, and network security zones. This approach systematically documents your enterprise architecture governance.

The ANSSI 2021 methodology for information system mapping is a structured four-level documentation framework covering business processes, application inventories, infrastructure components, and network segments to maintain a compliant view of system interdependencies and attack surface.

Mapping business assets to network infrastructure for an EBIOS Risk Manager study requires systematic four-level cartography linking business processes to application dependencies and underlying network security zones, satisfying the ecosystem mapping requirements of the risk assessment.

Yes, you can use this approach to identify unencrypted sensitive data flows. The security-focused analysis identifies critical attack surface vectors, including internet-exposed entry points and unencrypted sensitive data flows across the mapped application and infrastructure levels.

Yes, ANSSI cartography works for preparing a security homologation dossier. The structured four-level mapping satisfies regulatory requirements for security homologation dossiers by providing comprehensive documentation of business processes, applications, infrastructure, and network zones.

The best way to document enterprise architecture attack surface for regulatory assessments is generating a structured four-level cartography following the ANSSI methodology, mapping business processes to infrastructure components and identifying critical security vectors like internet-exposed entry points.
