What can I do to make this more secure? - eviltoast

I’m just a novice at self hosting and I see a lot of talk about the risks of exposing stuff to the world. Here’s my setup:

-Rpi4 hosting Overseerr
-Desktop computer hosting Nginx and some Cloudflare DDNS update containers

Cloudflare directs request.domain.com to my home IP address. Nginx forces HTTPS and directs the request to the Pi.

Is there any risk in this setup or are there more steps I can take to secure it?

    If you utilize logins something like fail2ban would be a good addition, as well as something for anti-malware/hacking/injection prevention etc. when I had a public Nextcloud I had Apache set up with mod-security with the owasp rule set loaded.

    The biggest risks of hosting something public at home besides ddos attacks is scripts that get regularly run against any open port they can find on the internet that if successful could encrypt your data for ransomware etc. I personally realized this was all just for me and the wife and running the services through a vpn (ZeroTier was fantastically easy to set up) removed most of the risk while letting us access remotely

    Edit: ddos protection would also be adviseable I think cloudflare might have that built in though

      I tried looking into fail2ban but I haven’t successfully set it up yet.

      To my understanding, if they try to DDOS the domain then cloudflare will shut them out. However they could very well just DDOS my IP, at which point I’m like any other potential target.
