Re: problem is not IoT, it's no "home (as in private) networks".
So you reckon the average joe no IT experience 'I just want it to work' home user should suddenly become a network security expert and configure their home set-up correctly??
You do not understand non techies..
Most people get their router set-up by the nice young man who comes to install the broadband and never touch it again. Good luck turning those people into security experts. Heck, the broadband installer is normally a telecoms guy, not a networks expert either.
