Container security encompasses the practices and tools used to protect containerized applications throughout their lifecycle. This includes securing container images (scanning for vulnerabilities), runtime protection (monitoring container behavior), orchestrator security (hardening Kubernetes clusters), and network policies (segmenting container traffic). Container security differs from traditional security because containers share the host kernel and have ephemeral lifecycles. Key practices include using minimal base images, running containers as non-root, and implementing image signing.
