A comprehensive guide to hardening container registries using Harbor. Learn how to enforce strict image provenance and deployment security by integrating vulnerability scanning (Trivy), cryptographic image signing (Cosign/Notary), granular Role-Based Access Control (RBAC), immutable tag policies, and content trust. Essential for environments requiring high compliance and robust supply chain security.

This guide details how to implement secure, keyless software signing using the Sigstore ecosystem components (Cosign, Fulcio, Rekor). It establishes cryptographic provenance for container images and binaries by binding identity via OIDC, ensuring verifiable integrity and tamper-proofing throughout the CI/CD supply chain.
