The worst is when some devices require network access to function, as the only way to interact with them properly is via smart phone - robot vacuums come to mind.
I am not knowledgeable enough to be able to prevent it from unauthorised access in and out, beyond blocking whatever domain ranges I find online.
I really need to find time to take a network admin masterclass or similar..
..especially if I intend to convince the missus to do a full Ubiquiti rollout in our house.
Just a little advice. For devices you dont trust, dont go for specific blocking, but whitelist instead. Allow only whats neccesary.
If you are not sure what that it and cant find it online, monitor it's traffic for a bit and see what it tries to reach.
I try to do research ahead of time, but if that kind of "feature" slips past my due diligence, I just return it.
Same. And if I have to call say an HVAC guy or something I'll be annoying the whole time.
"I need whatever you've got that DOESN'T connect to the internet."
"Ok. Here's the thermostat I'll be installing"
"And it doesn't have the ability to access the internet? Like, at all?"
"Yeah."
"Cool."
