|---|---|---|
| CCC.LB.TH12 | Application-Layer Inspection Is Absent or Bypassed | The web application firewall may not be attached to the listener, may run in detection-only mode, or may be bypassed by traffic that is passed at layer 4 or carried over an upgraded WebSocket connection. Malformed or exploit payloads then reach backend targets without inspection, compromising the integrity and availability of those targets. |
