Overview

A pod security policy is an example of a Kubernetes policy.

Pod security policy is implemented by a set of specialized Kubernetes resources (PodSecurityPolicy), generic resources (ServiceAccount, higher level pod controllers such as Deployments, ReplicaSets and so on), the PodSecurityPolicy admission controller and other controllers, all working in concert to ensure that the pods are created within strict security assumptions, and the pods access various resources in a controlled, secured manner.
