I think if people actually knew the true extent of the debacle that industrial control protocols are, they would pass out. If you ever want nightmares, check out EtherNet/IP CIP protocol...
Of course, there are no security provisions whatsoever. If you can get a device on the LAN, you're golden. Every device, fully open to monitoring and control of every attached piece of equipment.
In the new world of inexpensive, battery powered LoRaWan to Ethernet bridges with tens of kilometers range, I can't even begin to imagine the industrial carnage we're heading for. A sufficiently funded attacker could find ways to implant remote monitoring andcontrol in virtually every facility, where they can get a minimum-wage cleaning staff member hired. That means -- pretty much every facility (short of military, perhaps).
I recently went to a LoRaWan workshop funded by my megacorp (a utility company). It felt like paying someone to try and sell you their stuff.
Anyway, what the LoRa did emphasize is that both the network layer and application layer are encrypted with different keys using AES. This means someone would have to compromise both layers to actually control the devices.
Buuut, given that both encryption keys are stored on the device, I bet someone will just walk up with a chip clip and read the keys right out of EEPROM and then the pretty lights will start.
Or they'll just hack the application servers. I've seen some really god awful pieces of software in use.
A vendor once told me "it's so easy to admin our device over the internet. Just go to 192.168..." And of course due to corporate politics we still bought that piece of shit.
Moteino (arduino-based wireless dev platform) supports LoRa if anyone is interested in digging into some current sub-$10 ISM transceivers and their capabilities. http://lowpowerlab.com/moteino/#lora it's also a great project to get started with arduino if you've never worked with it before. Really solid documentation.
