When I go to a cafe with my laptop, I run it in fully firewalled mode (no incoming connections of anysort).
At home, I want my machines to be more promiscuous. With the promiscuity comes various concerns. Whether it is my 1Password safe, my health and financial records, whatever - I don't want some $30 connected device to connect to my home network and publish a port to the outside world that permits tunneling into my inside network.
Unfortunately, outside of sandboxing/firewalling, I do not have the time to implement a tracking system to see what devices doing what.
Anyone else feel more safe with connected devices at home? What do you do?
