CIS Hardening as an Architectural Property

CIS Benchmarks define what a secure container looks like, but applied as configuration they drift across base images, runtimes, Kubernetes and host systems, and every audit restarts the remediation cycle. This architecture insight makes the case for treating CIS controls as invariants built into the container image: non-root users, a minimal attack surface and secure defaults that cannot drift at runtime. It shows how CleanStart produces CIS compliance evidence at build time, passes Docker Bench for Security and kube-bench checks, and carries the same baseline into SOC 2, PCI DSS, HIPAA and FedRAMP.
