I’m looking for some insights to confirm if my home server’s security is up to par against common cyber threats. Here’s a brief rundown of my setup:
External Ports: I’ve limited external access to only three ports:
Port 80 and 443 for Nginx-Proxy-Manager
Port 51829 for Wireguard VPN
Hardware:
I’m running a Raspberry Pi 4 and a Mini PC.
Both are connected to the router via Ethernet.
Network:
NPM is set up for reverse proxy.
SSL is enabled for local DNS - to avoid memorizing IP addresses.
Docker:
All applications are containerized and use network_mode: bridge.
Internet-Facing Services:
Only two services are exposed to the internet:
A media server
The Wireguard VPN
I’m using free DuckDNS domains, configured with NPM.
Firewall:
Currently, I’m relying on the default settings of Debian 12 and the Docker engine.
I haven’t set up any specific firewall rules.
Given this setup, do you think my security measures are sufficient? I’m particularly curious about the risks associated with my Docker containers and the exposed ports. Any recommendations or best practices you could share would be greatly appreciated!
Just in case, if you have jellyfin facing the web, jellyfin is not very secure, it has some vunurabilities unpatched for like forever
I personally would recommend hiding it behind the VPN, and making it available to everyone at home
Or as minimum or a good practice create locations in nginx to block for example logins outside of the VPN or house
So to login you need to be at home.or connected to the VPN (useful if you have other people using your services, so they they they can login at home, but continue using everything outside)
You are not logged in. However you can subscribe from another Fediverse account, for example Lemmy or Mastodon. To do this, paste the following into the search field of your instance: !selfhosted@lemmy.world
