My networking knowledge is basic and only enough to setup a standard home network.
I have a couple desktops, NAS boxes for my wife and I, and other stuff (TV, media streamer, etc.) connected to it.
The way things go, I am worried that we might see attacks on home and small businesses networks growing.
Therefore, I thought about having two networks, with one isolated from the other.
One would be for the stuff that requires Internet and another for inside-only stuff, such as the NAS boxes. However, that would fail at the desktops, since the NAS work as backups ands the desktops have Internet connection.
I currently use a Nighthawk router that also works as a cable modem. I also have a VPN and run Glasswire in some of my PCs.
What are measures, both on hardware and software, that I can implement to help, at least improving, the network security?
