The "OTA" stuff has to start with some physical access in most cases, but anything that has contact to the outside world needs to be firewalled from the rest.It was unfettered access to the vehicle through the OBD port that allowed the hacking to take place. That part of the story is usually left out. That is why we now have the SGW to deal with. The dealer tools are designed to work through it, everyone else has to work around it.
The very first "hacks" were done only because someone had physical access to plant a device on the bus.
These bits about steering and brake application you see on TV shows - it's not really that simple. They also show how you can insert a thumb drive and download all of the documents on a computer in a matter of 60 seconds. What a hoot. So people assume - I saw it on TV so it must be possible and that easy. I laughed when I saw an episode of NCIS years ago where a Navy computer expert remotely hacked into a car's systems and caused an accident. Yeah, right.
Now we have true outside access - so we have "SGW" which is a firewall. Call it whatever you want, it's a firewall.
It's filtering traffic to and from the OBD port, radio and so on.
It's the same reason we have a router with firewall capabilities in our homes.
Without that SGW/firewall, someone can plug a BT adapter onto the OBD port and use a phone or tablet and connect from quite a distance and trigger things - or shut things down.
