performing-container-image-hardening
Harden container images by minimizing attack surface, stripping unnecessary packages, implementing multi-stage builds, configuring non-root users, and applying CIS Docker Benchmark recommendations to produce secure, production-ready images. Use when building production container images, when compliance requires CIS Docker Benchmark adherence, or when shrinking image size to reduce vulnerability exposure from unused packages.

# Performing Container Image Hardening
## When to Use
- When building production container images that need minimal attack surface
- When compliance requires CIS Docker Benchmark adherence for container configurations
- When reducing image size to minimize vulnerability exposure from unused packages
- When implementing defense-in-depth for containerized workloads
- When migrating from fat base images to distroless or minimal images
**Do not use** for runtime container security monitoring (use Falco), for host-level Docker daemon hardening (use CIS Docker Benchmark host checks), or for container orchestration security (use Kubernetes security scanning).
## Prerequisites
