Hello guys, I’m have little to no experience when i have to deal with networking or cybersecurity.

I recently created a backend RESTful API on my Ubuntu VM on my personal desktop and dockerized the app, connecting it to a bridge network named ‘tunnel.’ I also have the Cloudflare Docker hosted in the same ‘tunnel’ network, which allows my local RESTful API Docker to be accessible via my domain and exposed to the internet.

Can anyone help me understand if this setup poses any security risks to my home network?

If so, what should I do to help reduce the risk? I have read that firewall helps, but does a restful api container developed with golang requires it?

    You can use the Cloudflare’s Application Access to secure it down.

    Under the ZeroTrust page > Access > Application.

    Add it there and only allow certain IP and use it via VPN.
