Container Security — Image Scanning, Runtime Protection
Secure base images, vulnerability scanning, rootless containers, and secrets management in Docker
Docker containers are everywhere. Even if you're deploying to a serverless platform like Vercel, the moment you add a database, a background worker, or any custom infrastructure, you're probably running containers. And containers introduce an entirely new attack surface that most developers never think about.
The common misconception is that containers provide security isolation. They don't — at least not by default. A container is a process isolation mechanism, not a security boundary. A misconfigured container can expose your host system, leak secrets, and give attackers a foothold into your infrastructure.
This lesson covers the practical steps to secure your containers — from the image you build to the runtime you deploy.
