Re: Airgap: Impossible
"What about when the IoT is all about devices with their own built in 4G/LTE modems with its own IPv6 address? This is what worries me. I fear that there will come a day where all my appliances will be able to dial home irrespective of my WiFi set-up or outbound firewall rules. Personally, I may decide "To hell with the warranty" and open the device and remove or destroy the transceiver."
And the moment you do, the appliance will either (1) stop working altogether, forcing you to replace it out of warranty (since opening the appliance to break the radio voided it), or (2) the device emits all sorts of annoying sounds so as to draw attention to it.
Worse yet, this will likely become standard issue for all appliances in future. Maybe even require any appliance not broken up to be retrofitted before being resold, at which point we may well be on our way to either 1984 or the Stone Age, with no third option.
