Thanks for the advice!

Why would you leave PermitRootLogin to yes? Doesn’t really matter, if root ca nit login anyways?!

You are right on restarting sshd. That’s a typo…

An other user also mentioned to not fill out the root password and it will disable root + install sudo. Guess I didn’t read the instructions properly. Will definable be adopted.

I agree on importing from Github, but I am unsure how many people have their keys there…

UFW on a virtual machine might not be needed, but also not really harmful. I do like having in on every machine for piece of mind. Also this guide can be used for bare metal installs.

Crowdsec is on the todo list!

Thanks again. I will keep updating my article 😊
