NATO Architecture Framework Version 4 (NAFv4) for CISOs

What does NATO Architecture Framework Version 4 (NAFv4) require of a CISO?

The NATO Architecture Framework Version 4 (NAFv4, current release v4.1, March 2026) is NATO's standard for developing and describing enterprise and system architectures: a methodology of architecting stages aligned with ISO/IEC/IEEE 42010 and ISO 42020, a grid of viewpoints (concepts, service, logical, physical resource, architecture foundation and architecture meta-data) and a meta-model, used by NATO bodies and Nations and the basis of the Unified Architecture Framework. Under NATO Architecture Framework Version 4 (NAFv4), which defines 95 controls, a CISO's work is deciding which controls you own outright, which you share and which belong to another team, then holding the evidence for the first group.

Which NATO Architecture Framework Version 4 (NAFv4) controls land on the CISO

NATO Architecture Framework Version 4 (NAFv4) defines 95 controls across 8 domains that directly affect the CISO role. Understanding which controls fall within your ownership, which are shared, and which are owned by other teams is the foundation of effective compliance management.
