How does vulnerability scanning differ across container registries?

AWS ECR integrates with Amazon Inspector for enhanced scanning using CVE databases. Azure Container Registry uses Microsoft Defender for Containers. Google Artifact Registry integrates with Container Analysis. Harbor supports multiple scanners (Trivy, Clair, Anchore) for flexibility.

What are the best practices for container image lifecycle management?

Implement image tagging policies (immutable tags, semantic versioning), retention policies to purge old images, automated vulnerability scanning on push, signing with Notary or Sigstore Cosign, and geo-replication to reduce pull latency across regions.

How should enterprises evaluate container registry security features?

Critical security features include image signing and provenance verification, role-based access control, private endpoint support, audit logging, network-level access restrictions (VPC/VNet endpoints), and integration with enterprise SSO/IdP through OIDC or SAML.
