Securing container registry images by implementing vulnerability scanning with Trivy and Grype, enforcing image signing with Cosign and Sigstore, configuring registry access controls, and building CI/CD pipelines that prevent deploying unscanned or unsigned images.

# Securing Container Registry Images

## When to Use

- When establishing security controls for container image registries (ECR, ACR, GCR, Docker Hub)
- When building CI/CD pipelines that enforce vulnerability scanning before image promotion
- When implementing image signing and verification to prevent supply chain attacks
- When auditing existing registries for vulnerable, unscanned, or unsigned images
- When compliance requires software bill of materials (SBOM) for deployed container images

**Do not use** for runtime container security (use Falco or Sysdig), for Kubernetes admission control (use OPA Gatekeeper or Kyverno after establishing registry controls), or for host-level vulnerability scanning (use Amazon Inspector or Qualys).
