Checklist Summary:

The Kubernetes Security Technical Implementation Guide (STIG) provides technical requirements for securing a basic Kubernetes platform version 1.16.7 and newer. A basic Kubernetes cluster is composed of a Kubernetes master, application programming interface (API) server, scheduler, controllers, etcd, and the worker nodes. There can be other components within a Kubernetes installation; however, those listed here are the basic components within every installation and are the ones covered in this STIG. Other components, such as a runtime and a container network interface (CNI), act differently depending on the installed software (runtime examples are Docker, containerd, rkt, and lxd) or plugin (CNI plugin examples are Flannel, Calico, Canal, and Weave Net). The component also determines what additional security can be implemented for Kubernetes. For instance, the CNI installed can determine if network policies can be implemented and what type of policies they are. Because of the differences in capacities, features of Kubernetes components are outside the scope of the Kubernetes STIG, but the components do need to be secured. To secure the components outside the scope of this document, use the specific vendor STIG or technology Security Requirements Guide (SRG). Kubernetes is also a portable, extensible, open-source platform for managing containerized workloads and services that facilitates both declarative configuration and automation. With the platform, services such as a DNS, firewall, router, and web console may also be deployed. These services are also outside the scope of this document and must follow the appropriate vendor-specific STIG, if one exists. If a vendor-specific STIG does not exist, the more generic technology SRG must be used. Services must also follow any guidance that pertains to the way the services are implemented.
