Would a firewall os be necessary in any capacity for home users? I have UFW on my ubuntu server and I know the home router has its own firewall and is suppose to be able to help prevent against certain attacks.
I have a friend that I rarely get to talk to and he mentioned something about an actual os thats nothing but a firewall so you could turn an old machine or a raspberry pi into one for enhanced security. However I don't know anything much about the physical firewalls. In my mind I feel like they'd be overkill.
Does anyone have any names of these that I could load on to either something like an Intel NUC or Raspberry Pi 2 ?
