Container Base Image Hygiene: An Underrated Lever for Red...
Swapping bloated base images for minimal ones can cut container CVE counts by 60-90% without touching app code. Here's the data and how to start.
Choosing Secure Node.js Docker Images
How to pick Node.js Docker images that stay small and secure: comparing slim, Alpine, and distroless variants, pinning versions, and scanning for CVEs.
Docker Hub Node.js Images: How to Pick and Harden the Right Tag

Alpine vs Distroless vs Ubuntu Base Images: Security Tradeoffs
Alpine is small, distroless is smaller, Ubuntu is comfortable. The real security question is CVE surface vs debuggability vs compatibility — with numbers.
Zero-CVE Images vs Hardening Your Own: Cost and Risk Compared
Buy zero-CVE base images or build hardened ones yourself? A cost-and-risk comparison with real numbers: engineering hours, subscription pricing, and CVE half-life.
Wolfi OS: The Linux Distribution Built for Secure Containers
Wolfi is not a general-purpose Linux distro. It exists to solve one problem: provide secure, minimal, up-to-date packages for container images. Here is why that matters and how to use it.
Container Base Image Selection: A Security-First Decision Framework
Your base image choice determines your container security baseline. Most teams pick based on size or familiarity, not security properties.
