Review network policies and firewall configs for AI agent control loops and execution sandboxes.

Checks

1. Egress Restrictions

  • Sandbox Network: Enforce default-deny egress. Allowlist absolute minimum required IPs/services.
  • Internal APIs: Block agent/sandbox access to internal cluster APIs, K8s services, and cloud metadata (e.g., 169.254.169.254) — on the credential ports (TCP 80 pre-NAT, 988 post-NAT), not on port 53, which is the Pod's resolver under Cloud DNS for GKE and reaches no token.
  • Exfiltration Vectors: Flag broad egress (e.g., 0.0.0.0/0) on agent pods.

2. Ingress & Invocation

  • Authorized Sources: Restrict agent API ingress to trusted upstream services (auth gateways, orchestrators).
  • Bypass Prevention: Flag LoadBalancer or NodePort exposure on main agent containers lacking strict ingress NetworkPolicies.
