Yeah, I see your point. No use to repeat the same you can read in other comments or in those 274772 guides online. I was trying to imply to just generally harden ssh because then brute-force attempts should be no issue, unless you log everything and the disk space gets maxed out :D

Fml… yes, I meant CrowdSec. Thanks for the hint

• harden sshd
• use fail2ban or even better CrowdStrike CrowdSec
• use a tool like the following to have a next-gen security solution: https://github.com/mrash/fwknop
