As for planes most of the bigger planes use more proprietary communications standards for their data transfers. I'm familiar with boeing and they used the ARINC 429 bus standard on the older aircraft but may be moving/moved to an ethernet based system. The Arinc system is not secure but requires special equipment to interface with it as its a weird +10v and -10v data system and you would need access to the electrical equipment bays. Do able? Maybe. Practical or dangerous? Not really. Also there is no centralized data bus that every system is connected to, there are several data busses for different systems.
