I have partial color blindness and glaucoma which I think aren't related to my inability to read dark themes. When I try to read white or light text on a dark background, something in my eyes start flashing and I develop a headache in less than 60 seconds, it's been like that my whole life.

Highly recommend blocking the ssh port on all public facing instances and machines. Remember the recent xz/ssh backdoor exploit that was discovered.

What if there is another backdoor lurking undiscovered?

Do what I did, only open ssh over a VPN, or at least restrict it to a specific inbound IP or CIDR block under your direct control.
