Configure Pod Security Admission on workload namespaces so pods that request spec.hostPID: true are denied at admission time. Use enforce for remediation because it rejects violating pods. Use warn and audit as rollout and visibility controls, but do not treat them as enforcement. For this control, baseline is sufficient because it prohibits hostPID, while restricted provides stronger hardening for workload namespaces that can meet the additional requirements. Update each workload namespace with the restricted enforcement label. kubectl label ns $NAMESPACE pod-security.kubernetes.io/enforce=restricted --overwrite If restricted is too disruptive for a valid workload namespace, enforce baseline as the minimum profile for this specific control.
