services / Azure / Kubernetes pod security policies (Arc-connected cluster)

PodSecurityPolicies are Kubernetes admission-control objects in an Azure Arc-connected cluster that constrain the security context of pods (e.g. privileged mode, hostPath, host namespaces, runAsRoot), acting as a cluster security/defense mechanism.

PSPs are a defensive admission control; their configuration reveals where privileged-pod restrictions are weak.

Deleting a PSP removes a pod admission-control defense, lifting restrictions that otherwise block privileged or host-accessing workloads.

Risks

1. Defense destruction (EVASION)

Scope: HIGH

This privilege may grant access to sensitive data from a single organizational function, or allow interruption of a service supporting a single organizational function.
