The growth of Internet of things (IoT) devices is increasing dramatically. IoT devices often have multiple interfaces and connectivity options, but these may not be communicated to a network in an automated fashion. Techniques are presented herein that extend the Manufacturer Usage Description (MUD) artifact so that it may be used to effectively communicate information about an IoT device’s multiple connectivity options to a network in an automated manner and to notify the network of possible interface vulnerabilities so that any number of different actions (e.g., alerts, configuration checks, etc.) may be performed.
