That’s the point. It taught me things that I wouldn’t learn if it weren’t for that scared feeling. I agree that some sensitive things are better off my server.

You should start small and keep only things you want to be public, and services under basic logins. First logins, maybe admin admin but slowly you will get better and also place fail2ban and crowdsec. Once you have enough confidence and years of service on your belt. You can trust it with sensitive files under heavy guard.
