As long as it's segregated that way. Someone was able to gain access to their Dr's office's network by accessing the wifi-enabled fish tank thermometer.
I forget if the details of how exactly they accessed it, but it was an example of an Internet of Things device making a security hole in a network.
That's more of an annoyance than a safety issue though. This is definitely one of those YAGNI things where it's not worth worrying about until it becomes a recurring issue, which is highly unlikely.
Personally, even the remotest possibility of someone broadcasting "evacuate your rooms, there is a fire/active shooter in the building" seems worth spending a few hours protecting against.
>>Do you think hotels aren't protected, to some extent
How are they protected against that, exactly? You can literally walk up to any fire emergency button on any wall on any floor, press a button and evacuate the entire hotel, why bother with this UDP streaming nonsense?
The threat to the perpetrator -- of 90 days prison time and a permanent criminal record of being a mischief-maker -- prevents people from pulling the alarm.
Sure, and to circle all the way back to the original point several posts up - why is this a deterrent to someone pulling a fire alarm but not for someone sending a fake UDP broadcast? The penalty will be exactly the same.
Harder to track down the person. Unless the hotel is logging every packet on its network and paying to archive the TBs of encrypted video streaming data that goes through every day. And it's a purely local network, so not like the NSA can help out.
Edit:
"Unauthorized" computer access is a serious federal crime under the CFAA, and that you did it as a joke is not a legal defense. Famous examples:
Hotels are reasonably protected to such an attack. There are almost always cameras in the elevator, and the electronics are typically, to some extent, tamper-resistant.
