A comprehensive guide to container security covering eight practices organized from build-time to runtime: securing container images with minimal base images (Distroless), CVE scanning with Trivy/Grype, and Cosign signature verification; reducing attack surface by running as non-root with read-only filesystems and dropped Linux capabilities; selecting tools that cover build, deploy, and runtime phases (Falco, Tetragon, OPA Gatekeeper, Kyverno); preparing container-specific incident response plans that preserve ephemeral pod evidence; conducting continuous audits against CIS Kubernetes Benchmark; enforcing least-privilege RBAC with workload identity federation; automating base image rebuilds triggered by updates and CISA KEV catalog; and hardening Kubernetes orchestration with Pod Security Admission Restricted profile, etcd encryption at rest, and audit logging with retention policies matching HIPAA/PCI DSS requirements.
