Started off by

Enabling unattended updates
Enable only ssh login with key
Create user with sudo privileges
Disable root login
Enable ufw with necessary ports
Disable ping
Change ssh default port 21 to something else.

Got the ideas from networkchuck

Did this on the proxmox host as well as all VMs.

Any suggestions?

Well if you are using strong passwords or no passwords from outside at all, but key auth only, i think you are pretty in the safe side. As i said, i have no ssh port open to the internet. Raising the ban time could only lead to banning myself. 😀

But for ports open to the outside, yes. I ppbly would do that too. Plus hardening the ssh config a bit

I have an open ssh port and I use key auth with password as well as crowdsec. Even if people get my ssh key they would still need to know the password.
