The cluster was silent except for the whir of pods starting up. Inside it, every request, every secret, every API call had to meet FedRAMP High Baseline controls—or nothing shipped.
FedRAMP High Baseline for Kubernetes access is not optional in high-security environments. It sets the strictest security requirements for federal workloads, protecting controlled unclassified information (CUI) and ensuring compliance across 421 controls in NIST 800-53. Meeting this standard means proving identity, encrypting data in transit and at rest, enforcing granular role-based access control (RBAC), and maintaining auditable change history for every action inside the cluster.
Kubernetes complicates compliance. The default configurations are open-ended. AuthN and AuthZ, if left at defaults, fall short of FedRAMP High Baseline. Engineers must configure strong identity providers, integrate short-lived credentials, and eliminate static kubeconfig sprawl. Every kubectl exec and port-forward must be logged. Admission controllers should enforce security context constraints. Network policies must be set to deny by default. Secrets management has to align with FIPS 140-2 validated cryptography.
