Containers bundle applications and dependencies, but their security depends on careful control across the lifecycle. This episode examines how images are built, stored in registries, and deployed in runtime environments. We highlight risks such as outdated base images, poisoned registries, and misconfigured container permissions. Hardening requires scanning images, enforcing signed artifacts, and controlling registry access.

At runtime, monitoring and policies ensure containers do not escape or interact in unintended ways. The exam frequently includes containerized app scenarios, where identifying weak links in the image-registry-runtime chain is key. By mastering these controls, you’ll be ready to handle both exam challenges and the complexities of securing containers in production. Produced by BareMetalCyber.com.
