In one illustrative example, a controller may operate to send a request message towards a user equipment (UE) which operates to communicate traffic in a session in a mobile network. In response, the controller may receive, from a user plane function which anchors the session of the UE, a response message which includes an identifier of the user plane function. The controller may verify whether a zone or security level value that is assigned to the user plane function matches a zone or security level value that is assigned to the UE. If the controller identifies a discrepancy between the zone or security level values, the controller may provide a notification indication to indicate the discrepancy. The UE may be an industrial Internet of Things (IIoT) device and the zone or security level values may be based on International Electrotechnical Commission (IEC) 62443.
