A SupplyChainBrain commentary dated October 9, 2026, argues that supply-chain organizations should require AI bills of materials (AI-BOMs) and model provenance records from vendors to manage cybersecurity risks. The authors—Foley & Lardner attorneys Chanley Howell, Vanessa Miller, Leighton Allen and R.J. McVeigh—say component-level records can help identify vulnerabilities, trace failures and establish vendor accountability.

An AI-BOM lists the components and dependencies that affect an AI system, including models and versions, training and fine-tuning datasets and their provenance, software and infrastructure dependencies, APIs, external services, update mechanisms and security-relevant configurations. Model provenance records where a model came from, who trained or modified it, what validation and security testing it received, and how changes were tracked. In 2026, the U.S. Cybersecurity and Infrastructure Security Agency (CISA) and its G7 partners issued guidance applying supply-chain transparency principles to AI, saying traditional security questionnaires do not capture AI’s distinctive cyber risks.

AI systems in supply chains may combine vendor applications, pre-trained foundation models, open-source machine-learning libraries, cloud-hosted inference services, customer operational data and vendor retraining cycles. Risks can arise from vulnerable code, insecure integrations, unclear data flows and dependencies controlled by subcontractors. A general vendor security questionnaire may not identify a product’s embedded open-source model, its training image-labeling service, the API used for live inference or the cloud provider hosting model weights.

The authors say provenance records can help investigate whether a failing logistics-routing, predictive-maintenance or demand-forecasting system reflects corrupted training data, a compromised model artifact, an unauthorized version change or ordinary model drift. The National Institute of Standards and Technology’s adversarial machine-learning taxonomy identifies attacks on training data, model parameters and code during learning, as well as deployed-model attacks such as evasion, data extraction and manipulation. Other cited risks include model poisoning through fine-tuning pipelines, insecure model serialization formats and prompt injection aimed at downstream integrations.

The commentary sets out six procurement steps: require vendors to provide a detailed AI-BOM; demand provenance documentation covering model origin, training and fine-tuning history, data sources, validation, security tests and known limitations; and require updates and advance notice when models, datasets, components or update pipelines change. It also recommends contractual assurances that disclosures are complete and accurate, prompt notice of compromised components or vulnerabilities, audit rights, and cooperation after incidents.

Transparency obligations should extend to subcontractors, cloud providers, data-labeling services, foundation-model providers and open-source components. Organizations should incorporate AI-BOMs and provenance packages into IT and operational-technology risk assessments, vendor management, incident-response plans, vulnerability management and AI governance, including programs aligned with ISO/IEC 42001. The authors say documentation needs requirements for accuracy, update frequency, retention and independent verification. They add that mature software bill-of-materials formats such as Software Package Data Exchange (SPDX) and CycloneDX exist, while AI-BOM standards are still evolving; vendors withholding details over intellectual-property concerns could offer escrow, third-party reviews or tiered disclosure under enhanced confidentiality protections.

The authors point to CISA, NIST, ISO/IEC 42001, the EU AI Act and international regulators as moving toward greater AI supply-chain transparency. They argue that organizations adopting AI-BOM and provenance requirements in vendor relationships can detect threats, assess vendors, preserve incident evidence and allocate responsibility when systems fail. They urge organizations to establish the requirements before standards fully mature or a breach forces action, saying the records can make opaque AI systems auditable and manageable.
