| The collection of requirements captured here in ``strictdoc`` form were developed in a breakout session at the NMFTA CTSRP November 2021 workshop. The breakout session group discussed a) the workable definition of a gateway device -- focusing especially on the attacker's perspective -- b) possible security requirements for those devices that are gateways (intentional or not) and c) attempted to tie those back to the security requirements for vehicle gateways which were outline by a vehicle network security expert whose presentation on the subject was delivered earlier that day. The workshop participants and the expert cannot be revealed here, except by their own actions since the workshop was held -- as is tradition -- under Chatham house rules. | ||
| Intended Gateway: | ||
| A device which had connections to multiple vehicle network domains (or segments) and is intended to transport, translate, filter/drop/rate-limit or encapsulate information from an Untrusted Network Domain (*UND*) to a Trusted Network Domain (*TND*). Any device which performs one or more of these functions is an intended gateway. See the section *Abstract (Intended) Gateway Core Functional Requirements* for more details. |

Can an intentional gateway move information from a TND to another TND (while not attached to an UND )? Have we covered that use case in these requirements?

I don't see why not... let's put it to the group #37
