Kubernetes clusters must adhere to FedRAMP guidelines which include policies around access control, system and information integrity, audit and accountability, risk assessment, incident response, configuration management, secure container images, hardening the Kubernetes control plane, applying network segmentation and enforcing traffic policies, controlling deployments with Admission Controllers, maintaining pod and namespace isolation, enacting pod security standards, implementing cluster runtime security and continuous monitoring. Ensuring FedRAMP compliance begins with building and storing secure container images using minimal base images and scanning for vulnerabilities with tools like Trivy or Clair. To harden the Kubernetes control plane, implement the CIS Kubernetes Benchmark, enable audit logging, and use OPA or Kyverno to enforce policies. Implementing isolation is crucial as it minimizes the blast radius by defining granular roles, creating service accounts with minimum necessary permissions, and using different namespaces. Pod security standards can be implemented at the namespace level to enforce security measures easily across all pods deployed in that namespace. Responding to anomalous behavior immediately is a prerequisite in FedRAMP, which means taking action fast if something is happening with your pods. Continuous monitoring is essential using tools like Grafana or Prometheus to detect deviations from FedRAMP requirements before they become critical findings. Achieving FedRAMP compliance for Kubernetes requires discipline, automation, comprehensive monitoring, and collaboration across all teams involved in the platform. Spacelift can help by providing a one-stop shop for provisioning, configuring, and orchestrating infrastructure while leveraging OPA engine, collaboration features, and dependency workflows with shareable outputs to shift to a shared security vulnerability.
