What else should I do for my home server security? (lemmy.world)

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.

Literally a single nmap command will tell me where you "hid" your ssh port.

Like the poster you're responding to said, it is good advice but not for security. It takes you off the hacker spam list, essentially.

Rereading this it sounds like I am disagreeing with you sorry. Just trying to reiterate your point.
