In one embodiment, an authorizing device (e.g., a gateway) receives a native protocol request packet from a requesting device destined to a serving device, and translates the native protocol request packet into an authorization protocol mapping. The authorizing device may then apply authorization protocol based authorization (e.g., OT protocol independent) to the native protocol request packet based on the authorization protocol mapping, and transmits the native protocol request packet toward the serving device in response to the authorization protocol mapping being authorized. In one embodiment, the techniques herein may also perform an audit in this manner.
