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. The pod security policy controls security sensitive aspects of the pod specification.
PodSecurityPolicy
The PodSecurityPolicy is a cluster-level resource that defines a set of conditions that a pod must run with in order to be accepted in the system, as well as defaults for the related fields.

PodSecurityPolicy Admission Controller
The PodSecurityPolicy admission controller is a piece of code within the API server that intercepts pod creation and modification requests and determines if the request should be allowed based on the requested security context and the available PodSecurityPolicies.
