Can someone please explain to me, a casual home user, why it's dangerous to expose my NAS login page to the internet?... (alien.top)

...without snark or jumping down my throat. I genuinely want to know why it's so unsafe.

I'm running a Synology DS920+, with my DSM login exposed through a Cloudflare tunnel. I have 2FA enabled, Synology firewall enabled with these rules in place. I also have this IP blocklist enabled.

After all of this, how would someone be able to break in via the DSM login?

Cyber Security seems to bring out weird bravado where people pretend like they know more than they do. This thread is literally dozens and dozens of people spouting nonsense.

The bottom line is if you're running a cloudflare tunnel with authentication on the tunnel itself to a trusted auth provider and then enable 2FA on that auth provider, you have a zero trust model that is about as secure as most modern companies. All of the people saying BUT WHAT ABOUT ZERO DAY are beyond dumb. Enable auto-updates on everything you can, script the rest. The chances of there being a zero day vulnerability to cloudflare and then a bot is able to hit your synology page which then has its own security they need to get past, it's not likely at all. Monitor your Synology login attempts just in case it's all built in.

I know, right? I'm not going to lie, it's very amusing reading some of these replies...

I was literally just posting this in hopes of learning a thing or two, as I've always loved tech and this is a hobby that has given me great joy over the last couple of years.
