We need something to firewall the Internets from our too-smart house stuff! Something like an inverse firewall. A waterwall.

- JadeNB 7y agoBlocking unwanted egress is already accepted as possibly part of the functionality of a firewall (see, e.g., https://en.wikipedia.org/wiki/Egress_filtering https://en.wikipedia.org/wiki/Egress_filtering ); there's nothing inherently 'reverse' about it. Indeed, note the symmetry in Wikipedia's definition of a firewall (https://en.wikipedia.org/wiki/Firewall_(computing) https://en.wikipedia.org/wiki/Firewall_(computing) ): > In computing, a firewall is a network security system that monitors and controls incoming and outgoing network traffic based on predetermined security rules. A firewall typically establishes a barrier between a trusted internal network and untrusted external network, such as the Internet.
- blackhaz 7y agoI was trying to joke here. The untrusted network in our case is the internal network. In that sense.

Sure, and I'm sorry to miss the joke; but I think that it's nothing new that the internal network is untrusted. Before one ever had connected and untrusted smart appliances, one still had untrusted software running on one's general-purpose computer, and it was (and remains) often desireable to fence off that software from the outside world. Little Snitch (https://en.wikipedia.org/wiki/Little_Snitch https://en.wikipedia.org/wiki/Little_Snitch), for example, was designed around exactly that idea.
