This is a friendly reminder to put a firewall in between your server and the wider internet, and no, I'm not talking about fail2ban. Which is good for lots of things, but I wouldn't rely on it alone.

Don't open SSH ports up to the entire world. Put a firewall in between your server and those who would do you harm. Lots of providers have network-based access controls, cloud firewalls, etc: use them.

Friends don't let friends run sshd out in the open. :P
