Supply Chain Security Toolkit

Use this toolkit to turn supply chain security guidance into supplier questions, evidence requests, review decisions, and reusable assurance records.

Start here when you need to assess a supplier, review product evidence, approve an update, prepare for audit or customer assurance, map a standard to evidence, or decide whether a product, component, vulnerability response, or supplier answer is good enough to rely on.

The toolkit is the practical part of the handbook. Use Practices & Controls to understand what should operate, and use Technology Options when a mechanism may help produce, protect, exchange, verify, or retain evidence.

If you are not sure where to begin, choose the decision you are trying to make.

Choose Your Task

Task	Start with
Assess a supplier	Supplier Security Questions, Evidence Checklist, Supplier Onboarding Evidence Package
Review product or component evidence	Evidence Checklist, Product Acceptance Package, Component Provenance Example
Approve an update or review a vulnerability response	Secure Update Approval, Vulnerability Response Evidence, Evidence Package Template
Judge whether evidence is strong enough	Weak vs Strong Supplier Answers, Evidence Maturity Model, Evidence Checklist
Map standards, technologies, or assurance claims to evidence	Standards to Evidence and Technology Mapping Workflow, Curated References, Technology Options

Core Toolkit

The core toolkit contains the reusable pages you will come back to when asking for, reviewing, packaging, or retaining supply chain security evidence.

Supplier Security Questions

Ask suppliers for evidence-backed answers rather than unsupported assertions.

Evidence Checklist

Review whether evidence is scoped, verifiable, retained, and tied to a decision.

Evidence Maturity Model

Distinguish assertions from documented processes, produced artifacts, verifiable artifacts, and lifecycle-retained evidence.

Evidence Package Template

Assemble evidence for supplier assurance, product acceptance, audit, update review, vulnerability response, and lifecycle monitoring.

Standards to Evidence and Technology Mapping Workflow

Map standards expectations to practices, evidence requirements, technology options, and mapping confidence.

Worked Examples

Worked examples show the handbook's evidence model in realistic scenarios. Use them when a checklist or template is too abstract and you need to see what stronger evidence looks like.

Supplier Assurance

Start with the supplier onboarding evidence package and weak vs strong supplier answers.

Product and Component Review

Use the product acceptance package and component provenance example to see reviewable product evidence.

Lifecycle Decisions

Use secure update approval and vulnerability response evidence examples for update and remediation decisions.

Where Different Readers Should Start

Procurement teams should start with supplier questions, the evidence checklist, and the supplier onboarding example.

Product security teams should start with the evidence checklist, product acceptance example, secure update approval example, and vulnerability response example.

Suppliers should use the evidence package template, maturity model, and worked examples to understand what a buyer may expect.

Auditors, assessors, standards participants, and compliance teams should start with the evidence checklist, maturity model, standards mapping workflow, curated references, and glossary.

Technical implementers should use the mapping workflow alongside Technology Options, especially when selecting mechanisms that produce, protect, exchange, verify, or retain evidence.

Supporting References

These resources support interpretation and source discipline. They are useful alongside the toolkit, but they are not themselves evidence packages or review workflows.

Resource	Use it to...
Glossary	Align on assurance, evidence, provenance, lifecycle, verification, and technology-option terminology
Curated References	Find selected public guidance, standards, specifications, and source material
News and Analysis	Read short analysis of supply chain security incidents, policy changes, standards activity, and evidence practices

How This Fits the Handbook

Use Practices & Controls to understand what should operate. Use Technology Options when you need mechanisms that may produce, protect, exchange, verify, or retain evidence.

Use this toolkit when you need to ask for, assess, package, compare, or retain supply chain security assurance evidence.
