Context

Executive Order 14028 ("Improving the Nation's Cybersecurity", May 2021) directs federal civilian agencies to require secure-software practices from their software suppliers. OMB M-22-18 (September 2022) operationalised this by directing agencies to obtain self-attestations from software producers conforming to the NIST Secure Software Development Framework (SSDF, SP 800-218). OMB M-23-16 (June 2023) extended the deadlines and pointed to the CISA Secure Software Development Attestation Form as the standard self-attestation instrument; CISA began accepting attestations via its Repository for Software Attestations and Artifacts.

Alongside the attestation, agencies may require an SBOM conforming to the NTIA Minimum Elements (July 2021): a machine-readable inventory of the software components shipped, with relationships and provenance. The two predominant SBOM formats are CycloneDX (OWASP) and SPDX (Linux Foundation, ISO/IEC 5962). Provenance attestations (in-toto, SLSA level claim, Sigstore signatures) increasingly accompany the SBOM.

Process

1. Read prerequisites:

   • projects/000-global/ARC-000-PRIN-*.md (architecture principles, if present)
   • The project's REQ artefact — extract INT-* (integration requirements), NFR-SEC-*, plus any procurement requirements
   • The project's NIST 800-53 control-tailoring artefact — for SR and SA family implementation evidence
   • The project's HLD / DLD artefact — for component inventory and build pipeline architecture
   • Any vendor / third-party software inventory under projects/<id>/vendors/
   • .arckit/templates/_partials/RENDERING.md

2. Read the template:

   • First, check .arckit/templates-custom/us-sbom-eo-14028-template.md (user override)
   • Then, .arckit/templates-custom/us-sbom-eo-14028-template.md
   • Fallback, .arckit/templates/us-sbom-eo-14028-template.md

3. Use scripts/bash/create-project.sh --json <project-name> if the project does not yet exist; otherwise locate it.

4. Use scripts/bash/generate-document-id.sh <PROJECT_ID> SBOM --filename for the artefact filename. The type code for this command is SBOM.

5. Generate the following sections:

   • Software Product Identification — producer name, product name, version, release date, deployment targets, whether the product is delivered as software, SaaS, IaaS/PaaS-hosted application, or hybrid.
   • Applicability Determination — does M-22-18 apply? Cite the M-22-18 §2 definition of covered software (software developed after 14 September 2022 used by the federal government). Note any open-source components and the producer-of-record for each.
   • CISA Self-Attestation Form Content — populate the CISA attestation form fields per OMB M-22-18 §III: (1) the software is developed and built in secure environments per SSDF PO.5; (2) the producer has documented audit trails / provenance for internal code and third-party components per PS.3, PW.4; (3) the producer employs automated tools to maintain trusted source-code supply chains per PW.4, PW.7, PW.8; (4) the producer maintains provenance for internal code and third-party components consumed; and additional sub-items per the current CISA form. Each item: status (Yes / No / Partial), evidence references, remediation plan.
   • SSDF Practice Crosswalk — table mapping each CISA attestation item to SP 800-218 practices (PO, PS, PW, RV) and to NIST 800-53 SR / SA family controls.
   • SBOM Format Choice — CycloneDX or SPDX, with rationale. Note the version (e.g. CycloneDX 1.6, SPDX 2.3) and the tooling used to generate the SBOM.
   • NTIA Minimum Elements Checklist — for the SBOM artefact confirm presence of: Supplier name; Component name; Version of the component; Other unique identifiers (PURL, CPE); Dependency relationships; Author of SBOM data; Timestamp; plus the data fields, automation support (machine-readable), and practice elements (frequency, depth, known unknowns, distribution and delivery, access control, accommodation of mistakes).
   • Provenance and Signing — SLSA level claim (1 / 2 / 3 / 4) with rationale, signing strategy (Sigstore cosign, GPG, vendor key), in-toto attestation layout if used.
   • Vulnerability Management Posture — VEX (Vulnerability Exploitability eXchange) production cadence, CVE disclosure policy, coordinated-disclosure contact, mean-time-to-patch targets.
   • Exception Request — if a self-attestation cannot be made for one or more items, document the M-22-18 exception process: which items, why, compensating controls, agency CIO + OMB notification status, expiry of the exception.
   • Distribution Plan — where the attestation will be lodged (CISA Repository for Software Attestations and Artifacts), where the SBOM will be distributed (agency CSO portal, supplier portal), and the access-control posture for SBOM consumers.

6. Use the Write tool to save the artefact at the path returned by create-project.sh + generate-document-id.sh.

7. Emit a short summary to the user — attestation status (Full / Partial / Exception), SBOM format and component count, SLSA level claim, open exceptions, and the lodging date target. Do not echo the full artefact.

Handoffs

The attestation and SBOM directly evidence NIST 800-53 SR and SA family controls in $arckit-us-nist-800-53. SBOM-format choice, signing strategy, and any exception requests should be captured as ADRs via $arckit-adr. Components with known unmitigated vulnerabilities and any open M-22-18 exceptions feed $arckit-risk.

Important Notes

• The attestation is from the software producer, not the agency — if the agency is procuring software, the supplier signs the CISA form. If the agency is producing software (in-house development or as a federal CSO), the agency is the producer and signs the form itself. Identify the producer-of-record before drafting.
• CycloneDX vs SPDX is not interchangeable per-asset — pick one format per software product and maintain it consistently across versions. Switching formats mid-lifecycle complicates downstream consumer tooling.
• The NTIA Minimum Elements are a floor, not a ceiling — modern SBOM consumers expect dependency-graph completeness, license metadata, VEX integration, and signed provenance. Treat the NTIA list as the minimum, then exceed it.
• SLSA level claims must be verifiable — claiming SLSA Level 3 or 4 without the corresponding build-pipeline isolation, hermetic builds, and signed provenance is non-compliant. If you cannot evidence the level, claim one lower.
• M-22-18 exceptions are time-bound — exception requests must specify the period, compensating measures, and remediation plan. Treat the exception as a clock running down, not as a permanent carve-out.

Suggested Next Steps

After completing this command, consider running:

• $arckit-us-nist-800-53 -- SR (Supply Chain Risk Management) and SA (System and Services Acquisition) control family implementations must cross-reference the attestation and SBOM.
• $arckit-adr -- SBOM format choice (CycloneDX vs SPDX), signing strategy (Sigstore, in-toto, SLSA level), and attestation exception requests warrant ADRs.
• $arckit-risk -- Components with known unmitigated vulnerabilities or attestation exceptions feed the risk register.
