GKE Privileged Pod Created
Detects successful GKE audit events where a pod is created with allowPrivilegeEscalation enabled. This weakens container isolation and can help an attacker escalate toward host access. Standalone pods are included; workloads owned by ReplicaSet, DaemonSet, or StatefulSet controllers are excluded.

Review user.email, orchestrator.resource.name, orchestrator.namespace, and the pod spec in gcp.audit.request.
Confirm whether allowPrivilegeEscalation is required for the workload.
- Identify the actor and source (
user.email,source.ip,user_agent.original). - Inspect container images and securityContext in the audit request payload.
- Correlate with RBAC changes, secret access, or exec activity from the same identity.
- One-off admin debugging pods; tune by user or namespace when documented.
The GCP Fleet integration with GKE audit logs enabled is required to be compatible with this rule.
