Hardened images address supply chain vulnerabilities by removing unnecessary packages and outdated dependencies from standard base images. Developers can swap existing base images with hardened equivalents with minimal changes to their Dockerfile, though some debugging tools may be missing. Docker also released hardened Helm charts that follow security best practices by default for Kubernetes deployments. ## Full article daily.dev links to this article rather than hosting it.
