services / Azure / AKS pod security policies

A PodSecurityPolicy is a cluster-wide Kubernetes admission-control object that constrains what pods may run (privileged mode, host namespaces, hostPath/hostNetwork, capabilities). On AKS this is a data-plane resource governing the cluster's pod-security defense posture.

PSPs are a security-enforcement defense mechanism: weakening or removing them lets privileged/host-mounting pods run, which is the standard path to container breakout and node/cluster compromise.

Deleting a PodSecurityPolicy removes the admission-control defense and the security-policy object that restricts pod privileges, lifting constraints that would otherwise block privileged/host-access pods.

Risks

1. Policy destruction (CRITICAL)
2. Defense destruction (EVASION)

Scope: CRITICAL

This privilege may grant access to sensitive data from a significant fraction of organizational functions, allow interruption of critical organizational services, or its exploit could lead to significant privilege escalation.
