Category - Subcategory	Kubernetes - Native Security Controls
Provider	OTHER
Severity	LOW
Framework	Helm, Kubernetes, Kustomize

Impact

Reject creating pods that do not match Pod Security Policies. A Pod Security Policy is a cluster-level resource that controls the actions that a pod can perform and what it has the ability to access. The PodSecurityPolicy objects define a set of conditions that a pod must run with in order to be accepted into the system. Pod Security Policies are comprised of settings and strategies that control the security features a pod has access to and hence this must be used to control pod access permissions.

NOTE: When the PodSecurityPolicy admission plugin is in use, there needs to be at least one PodSecurityPolicy in place for ANY pods to be admitted. See section 5.2 for recommendations on PodSecurityPolicy settings.
