Secures container registry images (ECR, ACR, GCR, Docker Hub) by scanning with Trivy and Grype, signing with Cosign and Sigstore, configuring registry access controls, and building CI/CD pipelines that block unscanned or unsigned images. Use when establishing registry security controls or enforcing scan/signature checks before image promotion.
