How to confirm home server security (alien.top)

Is there a way to confirm that my home server's security is sufficient for most common attacks?

Externally, I only have the ports 80, 443 (Nginx-Proxy-Manager) and 51829 (Wireguard VPN) enabled on the router.

I have a Rpi4 and a mini PC connected to the router via ethernet cable. And I am using NPM for reverse proxy. Also enabled SSL for local DNS so I don't have to keep typing the IP addresses for each server.

All my apps are docker containers and they all use network_mode: bridge.

And finally, I have only two services open to internet. The media server and the Wireguard VPN. Got the free DuckDNS domains and configured in the NPM.

I haven't done any specific firewalls. Just using default Debian 12 settings and default Docker engine settings.

yes, there are professional third party cybersecurity auditors you can hire, but I doubt anyone here would ever need them.

Please people, stop being paranoid about your security. close up all unnecessary ports, and that's what you can do on your end. whatever else, if the service binding to an open port has security vulnerabilities you don't know, the project team may very well be unaware of it either, and there's nothing you could do.

also, if you have multiple users using your service, then it's their password strength that you should be worrying the most, not your infrastructure.
