SoftwareSupplyChain

SoftwareSupplyChain refers to the end-to-end processes and systems by which software is sourced, built, distributed, and deployed. It covers the selection of third-party components, open-source dependencies, automated build and release pipelines, and the delivery of software artifacts to users and production environments.

Key components include a software bill of materials (SBOM) that inventories components and licenses; dependency management and version pinning; continuous integration and continuous deployment pipelines; code signing and provenance; artifact repositories; and governance mechanisms for license compliance and security.

Security and risk: The integrity of software at scale depends on its supply chain. Attacks may target compromised dependencies, counterfeit packages, tampered build processes, or supply chain manipulation. Practices include software composition analysis, vulnerability management, secure coding and testing, SBOM maintenance, and reproducible builds.

Standards and governance: Industry groups promote SBOM standards such as SPDX and CycloneDX; frameworks like the NIST Secure Software Development Framework (SSDF) and secure development lifecycle guidelines; vendor risk management; and policies for license compliance, provenance, and traceability.

Challenges and examples: Managing the complexity and velocity of dependencies, drift, and trust across multiple vendors. Notable incidents, such as the SolarWinds and other supply chain attacks, illustrate the potential impact of compromised update mechanisms on downstream users.
