Supply Chain Security
Supply chain security refers to the comprehensive practice of identifying and managing risks across all stages, participants, and dependent components involved in the production and delivery of a product or service. In software, this primarily covers security review of third-party code, open-source dependencies, build tools, and distribution channels. In physical supply chains, it involves assessing the trustworthiness of raw material sources, logistics nodes, and suppliers. The core objective is to prevent systemic risks introduced by malicious code, tampering, or vulnerabilities from external sources.

Mature tools adopt offline signing, multi-signature, transparency logs (such as Sigstore), and rollback-capable version pinning mechanisms to reduce the supply chain risk brought by self-updating.
Some security researchers recommend that for critical business scenarios, downloaded weights should undergo sanitization experiments or behavioral audits rather than relying solely on the reputation of the source.
Signing published packages with GPG keys allows users to verify that the version was genuinely produced by a legitimate build process, thereby reducing the risk of dependency poisoning attacks.
To address supply chain hardware threats, a trusted supplier system should be established and source traceability implemented for critical components.
GPG signing is a digital signature mechanism based on asymmetric encryption; in GitHub's release workflow, maintainers use a private key to sign release artifacts, and users can verify the signature's validity using a public key.
