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.

    Containers are not a security barrier. They cannot be, they never will be.

    Not entirely true. If you’re hosting multiple game servers on one machine, for example, it’s best to run each instance in a container. Game servers, by their nature, are required to have public IPs and ports, and some of them run on old engines that are vulnerable to various DoS methods. If your server is attacked, it might crash the container(s), but it can’t bring the whole server down.
