SBOM Attestation for Software Health
by Nick Clark | Published April 25, 2026
Health monitoring includes Software Bill of Materials (SBOM) attestation. Each unit's software composition is credentialed; deviations from declared SBOM enter as health-monitoring events.
What It Specifies
Each unit declares its SBOM: software components, versions, and hashes. The architecture verifies the running software against the declared SBOM; deviations enter as credentialed monitoring events.
SBOM attestation events carry: unit identity, declared SBOM, observed SBOM, deviation analysis, monitoring authority signature. Downstream operations admit the events against admissibility.
Why It Matters Structurally
Software-integrity monitoring without SBOM faces structural ambiguity. The expected software composition is implicit; deviations cannot be evaluated against explicit expectation.
SBOM attestation produces structural specificity. The expected composition is declared; deviations are evaluated against the declaration; monitoring events carry structured semantics.
How It Composes With Mesh Operation
The architecture defines the SBOM-declaration format, the deviation-evaluation primitives, and the event recording. Implementations apply the architecture; monitoring operations proceed within the framework.
SBOM composes with other features. Cross-mesh SBOM federation, byzantine-robust SBOM evaluation, and dispute mechanism for SBOM disputes all build on the SBOM primitive.
What This Enables
Defense software integrity gains structurally-supported attestation. Civilian critical-infrastructure software integrity gains the same.
The architecture also supports SBOM evolution. As SBOM standards (SPDX, CycloneDX) mature, attestation protocols update through governance procedures.
