Abstract: A process to protect secure communication sessions from a network device that may have been subjected to a malicious network attack or otherwise the source of malicious network traffic. A cellular-connected network device, such as an IoT gateway, may receive data from one or more IoT devices. The cellular-connected network device may also communicate with a datacenter via a communication tunnel. The network device may include a usage profile reference. The network device, before transmitting data received from the IoT devices, may transmit the usage profile reference to the datacenter for authentication purposes. The datacenter may use the usage profile reference to resolve a usage profile that the usage profile reference references. Using the usage profile, the datacenter may negotiate with the cellular-connected network device to restrict the types of data that is transmitted between the datacenter and the cellular-connected network device.
