The Hidden Risks in Your Docker Images and How Hardened Images Fix Them

Containers have transformed how modern applications are built and shipped, but container images remain one of the most overlooked security risks in the software supply chain. Many production workloads unknowingly run images that include unnecessary packages, outdated dependencies, and hidden vulnerabilities.

In this talk, I will explore how Docker Hardened Images help reduce the attack surface by providing minimal, secure, and continuously maintained base images designed for production environments. We will break down the architecture of hardened container images, how they differ from traditional base images, and how they fit into a secure container supply chain.

Participants will walk away with actionable strategies to build secure containers and strengthen their container infrastructure.
