Welcome to the SupplyChainSecurityHandbook.com project.

Our mission is to build a practical, vendor-neutral reference for teams that need to manage trust across complex technology supply chains. The handbook focuses on products and platforms where hardware, firmware, software, suppliers, credentials, updates, and lifecycle services all affect security and assurance.

Supply chain security expectations are moving beyond supplier assertions and one-time questionnaires. Buyers, suppliers, manufacturers, operators, auditors, and ecosystem participants increasingly need evidence that identity, provenance, integrity, updates, vulnerability handling, and lifecycle controls are operating.

This handbook is designed to bridge the gap between standards, threats, and evidence-backed assurance. We aim to help teams move from asking "What does this standard, procurement expectation, audit need, customer assurance request, or threat pattern mean?" to knowing "What practices, evidence, lifecycle controls, and implementation options should we consider?"

If you are new to the handbook, start with Start Here and choose the reader journey that best matches your role.

What You'll Find Here​

  • Standards & Threats: Starting points for standards, regulations, assurance expectations, threat patterns, lifecycle failure modes, and product trust decisions.
  • Practices & Controls: Applied supply chain security practices, lifecycle maps, the 10 Best Practices for Supply Chain Security, and operating guidance for supplier assurance, product acceptance, release governance, updates, audit readiness, and implementation planning.
  • Technology Options: Role-based interpretation of trust anchors, attestation, transparency artifacts, signing, updates, exchange workflows, repositories, logs, retention, and tooling that may help produce, protect, exchange, verify, or retain evidence.
  • Resources: Supplier questions, evidence checklists, evidence maturity guidance, evidence package templates, worked examples, standards and technology mapping workflows, glossary entries, and curated references.

This is a community-oriented handbook. The site will grow over time as the core guidance, evidence mappings, and practical resources become more complete.
