02 / SBOM

What SBOM requires

The 2026 baseline expressly covers AI software but adds no AI-specific fields; CISA and G7 partners issued separate AI SBOM minimum elements in May 2026 as a supplement.

01Produce SBOMs with the 17 minimum data fields, including component producer, version, identifiers, hash value and license.
02Record SBOM author, timestamp, tool name and version, and generation context (lifecycle phase).
03Sign the SBOM so recipients can confirm it is unaltered (SBOM Author Signature).
04Use machine-processable formats such as SPDX or CycloneDX and update the SBOM when components change.
05For federal cloud contracts with SBOM terms, provide an SBOM of the runtime production environment on request.

03 / C-SCRM

What C-SCRM requires

Third-party models, training data, AI APIs and AI-enabled software are supply chain elements under this guidance. It contains no AI-specific controls.

01Set a C-SCRM strategy, policy and implementation plan at enterprise, mission and system levels.
02Assess supply chain risk for products and services before and during acquisition.
03Apply and tailor supply chain controls (SP 800-53 SR family and enhanced overlays) to systems.
04Flow C-SCRM requirements into supplier contracts and monitor supplier compliance.
05Maintain visibility into components, provenance and suppliers, and respond to supply chain incidents.

Optional evidence · where Planisphere fits

Keep a record anyone can check

When your team meets a duty, Planisphere can seal the event it reports as a receipt.

A disclosure shown, a review signed, a model change approved: the event your system reports.

02 · PlanisphereSeal it

The event becomes a sealed receipt, dated and attributed to whoever is signed in.

03 · AnyoneCheck it

Paste the receipt into Verify. No account or key.

A record supports your compliance evidence process. It is not a legal finding or a certification. Systems that call Planisphere's gate API can also hold or refuse an action before it runs.
