Well‑Architected Software Supply Chain Best Practices
🔒 This AWS Security blog post outlines best practices for defending against software supply chain attacks, motivated by recent npm incidents like Shai‑Hulud and axios. It emphasizes reducing long‑lived credentials by using temporary credentials (AWS CLI login, IAM Identity Center, OIDC) and centralizing secrets with AWS Secrets Manager or Systems Manager Parameter Store. The article advocates layered defenses including MFA, multi‑approver workflows, artifact signing with AWS Signer, central package repositories using CodeArtifact, image scanning with Amazon Inspector, and provenance attestations for npm packages.
