So I’m relatively new to server hosting. (But experienced with remote web hosting from providers.) After about a year of fighting to run Nextcloud on a hosting company and finally losing everything from the cPanel vulnerability a few months ago, I broke down and launched my own home server. I’m looking for advice to maximize security.
CachyOS Linux with ClamAV Docker via Portainer Nextcloud (E2EE), Immich, DocuSeal and NoteTrace Routed through a domain and subdimains via Zero Trust Cloudflare Tunnel and Cloudflare DNS.
I have regular redundant backups both onsite and offsite with Duplicati.
My passwords for OS and all admin dashboards are extremely long, unique, random strings managed by Bitwarden.
I know just enough about this stuff to get into trouble. What else should I setup? I have little to no monitoring going on and don’t know much about that direction.
And if you do, make sure to read them thoroughly. Most of these rules apply to for-profit hosting only. Or they’re vague and they can’t enforce them. And most contracts don’t have rules anyway. They’re mostly concerned with you not attracting DCMA complaints or a virus hosting some spam email server.
