Supply Chain Security Evidence Package Template

Use this template to assemble evidence for supplier assurance, product acceptance, customer assurance, audit readiness, update approval, vulnerability response, or lifecycle monitoring.

An evidence package should make the decision, scope, artifacts, verification path, gaps, exceptions, owners, and retention expectations visible. It should show why the evidence is sufficient, conditional, incomplete, or not yet usable for the decision.

Use Supplier Security Questions to ask for evidence. Use the Evidence Checklist to judge whether it is sufficient. Use this template to assemble and retain the evidence package.

warning

An evidence package does not make weak evidence strong. It makes the evidence, assumptions, gaps, exceptions, and decision visible. Unsupported claims should remain visible as gaps, not be repackaged as assurance.

When to Use This Template

Use this template when evidence needs to support a decision that may be reviewed later.

Common decisions include:

  • supplier approval, renewal, continued use, remediation, or rejection;
  • product acceptance, quarantine, rejection, or acceptance with conditions;
  • update approval, staged rollout, exclusion, rollback, or recovery;
  • vulnerability remediation, mitigation, communication, or risk acceptance;
  • audit, customer assurance, standards mapping, or lifecycle review.

Template

FieldWhat to record
Decision supportedThe decision this package supports, such as supplier selection, product acceptance, update approval, vulnerability response, audit review, repair return-to-service, transfer, or decommissioning.
Decision outcomeThe result of the review, such as accepted, accepted with conditions, rejected, remediation required, risk accepted, or pending.
Decision ownerThe person, role, or team accountable for the decision and any follow-up.
Practice/control supportedThe practice and control that produced or requires the evidence.
Product, service, supplier, component, release, or lifecycle scopeThe exact scope covered by the package, including product/version binding where relevant.
Evidence includedArtifacts, records, claims, measurements, attestations, certificates, manifests, SBOM/xBOMs, update records, vulnerability records, lifecycle-state records, logs, or audit material.
Producer/sourceThe supplier, product team, manufacturer, service owner, verifier, tool, repository, or system that produced each evidence item.
Consumer/recipientThe buyer, operator, customer, auditor, assessor, product team, verifier, or relying party that will use the evidence.
Generated whenWhen the evidence was generated and what event produced it.
Verified whenWhen the evidence was reviewed or appraised.
Verification methodHow origin, integrity, freshness, consistency, scope, or lifecycle relevance was checked.
Freshness/dateThe date, timestamp, version, status, or review cadence that shows whether the evidence is current enough.
Known gapsMissing evidence, unclear scope, weak provenance, stale artifacts, unsupported claims, or unresolved questions.
Exceptions/risk acceptanceAny approved exception, residual risk, compensating action, owner, review date, and rationale.
Retention ownerThe team, repository, system, or role responsible for retaining and refreshing the package.
Related technology optionsMechanisms that may help produce, protect, exchange, verify, or retain the evidence.
Follow-up actionsRemediation, additional evidence requests, retest, renewal, refresh, customer communication, or review actions required after the decision.

Package quality checks

  • Is the evidence tied to a decision rather than collected for its own sake?
  • Is the product, supplier, component, release, or lifecycle scope clear?
  • Can the recipient identify who produced each artifact and when?
  • Can origin, integrity, freshness, consistency, or lifecycle relevance be checked?
  • Are gaps, exceptions, and risk acceptances visible?
  • Is the package retained somewhere it can be found, explained, and reused later?

Package Variants

Use the same template fields, but emphasize different evidence depending on the decision.

Supplier review package

FieldExample focus
Decision supportedSupplier selection, renewal, continued use, remediation, or rejection.
Practice/control supportedSupplier evidence requirements, supplier assurance review, contractual evidence clauses, remediation tracking.
ScopeSupplier, product or service, contract scope, critical sub-tiers, support services, and assessed version or release.
Evidence includedSupplier declarations, questionnaire responses, sub-tier declarations, dependency records, SBOM/xBOMs, vulnerability commitments, incident notification terms, remediation plans.
Known gapsUnsupported sub-tier visibility, unavailable artifacts, stale certifications, missing product/version binding, unclear support boundary.
Retention ownerProcurement, supplier assurance, product security, or contract owner.

Product acceptance package

FieldExample focus
Decision supportedAccept, reject, quarantine, remediate, or accept with conditions.
Practice/control supportedIdentity verification, provenance review, integrity/configuration check, transparency artifact review, update/vulnerability review.
ScopeProduct, component, platform, firmware load, supplier-provided service, serial number, release, or deployment cohort.
Evidence includedIdentity evidence, provenance records, certificate or credential issuance records, measurements or attestation results, SBOM/xBOMs, update history, vulnerability status, acceptance checklist.
Known gapsMissing provenance, stale vulnerability status, unverifiable identity, incomplete SBOM scope, unavailable reference values, unclear update history.
Retention ownerProduct owner, asset owner, acceptance authority, or lifecycle monitoring owner.

Audit or customer assurance package

FieldExample focus
Decision supportedCustomer assurance response, audit response, certification preparation, internal control review, or evidence gap remediation.
Practice/control supportedControl evidence register, standards mapping review, evidence retention control, audit package preparation, exception visibility.
ScopeStandard, control, customer request, audit period, product line, supplier, lifecycle stage, or assurance claim.
Evidence includedControl-to-evidence mappings, source references, audit packs, customer assurance packs, review notes, verification metadata, exception records, remediation plans.
Known gapsUnsupported control claims, expired evidence, unclear source reference, weak verification path, unresolved exception, missing retention owner.
Retention ownerAudit owner, compliance owner, customer assurance owner, control owner, or evidence repository owner.

Update or vulnerability review package

FieldExample focus
Decision supportedUpdate approval, update eligibility, deployment, rollback, vulnerability remediation, vulnerability status communication, or risk acceptance.
Practice/control supportedUpdate approval workflow, update eligibility check, update signing control, affected-product analysis, remediation tracking, evidence refresh.
ScopeProduct, version, release, deployment cohort, vulnerability identifier, affected component, customer environment, or lifecycle state.
Evidence includedUpdate approvals, signing records, update manifests, installation logs, rollback evidence, affected-product analysis, VEX-like status records, remediation records, risk acceptance records.
Known gapsUnclear affected-product mapping, missing installation logs, stale vulnerability status, unverifiable update package, unresolved remediation, unsupported rollback evidence.
Retention ownerProduct security, release owner, update service owner, vulnerability response owner, or lifecycle monitoring owner.

Retention Does Not Improve Weak Evidence

Retention does not make weak evidence strong. It preserves evidence usefulness only if the original artifact, context, and verification path are meaningful.

Use this template with Evidence Repositories, Logs, and Retention when evidence needs to support later audit, renewal, vulnerability response, transfer, repair, incident review, or decommissioning decisions.
