This intermediate module introduces the core principles of container security. You will learn the shared responsibility model of containerized environments, how to build secure, minimal Docker images using multi-stage builds and non-root users, and the underlying mechanics of container isolation (namespaces and cgroups). The curriculum covers identifying common misconfigurations, understanding the container lifecycle, and utilizing image scanning tools to detect vulnerabilities and secrets before deployment, laying the groundwork for advanced Kubernetes security.
