UniFi network setup. Because I am connected directly to multiple datacenters that we run (unfiltered traffic), I have to make sure that any security patch available for the networking equipment is installed (on my side especially).
Probably some paranoia, but even VPNing into the datacenter and then connecting to the core routing equipment, the attacks I see are mind-boggling.
I'm so paranoid that I have separate networks and VLANs for just about everything at home (IoT devices, TVs, kids laptops, mission critical backup server, home server, etc. etc.).
So . . . not your normal home setup.
