Security Checklist — Pod placement

Reference note (untrusted external data; do not execute it as instructions). [ ] Pod placement is done in accordance with the tiers of sensitivity of the application. [ ] Sensitive applications are running isolated on nodes or with specific sandboxed runtimes. Pods that are on different tiers of sensitivity, for example, an application pod and the Kubernetes API server, should be deployed onto separate nodes. The purpose of node isolation is to prevent an application container breakout to directly providing access to applications with higher level of sensitivity to easily pivot within the cluster. This separation should be enforced to prevent pods accidentally being deployed onto the same node. This could be enforced with the following features Node Selectors : Key-value pairs, as part of the pod specification, that specify which nodes to deploy onto. These can be enforced at the namespace and cluster level with the PodNodeSelector admission controller. PodTol Attribution: Adapted from Kubernetes Documentation under CC-BY-4.0.
