How do you all handle security and monitoring for your publicly accessible services? (lemmy.world)

This is a continuation of my other post

I now have homeassistant, immich, and authentik docker containers exposed to the open internet. Homeassistant has built in 2FA and authentik is being used as the authentication for immich which supports 2FA. I went ahead and blocked connections from every country except for my own via cloudlfare (I'm aware this does almost nothing but I feel better about it).

At the moment, if my machine became compromised, I wouldn't know. How do I monitor these docker containers? What's a good way to block IPs based on failed login attempts? Is there a tool that could alert me if my machine was compromised? Any recommendations?

EDIT: Oh, and if you have any recommendations for settings I should change in the cloudflare dashboard, that would be great too; there's a ton of options in there and a lot of them are defaulted to "off"

I've been playing around with the voice assistant stuff in homeassistant and it seemingly needs a public url to get all the features. I could be wrong about that though?

I put authentik in front of immich to handle authentication so that I would need need a 2FA code

Most definitely does not need a public URL for Assist in HA. Not sure where you read that.

It sounds like you need a VPN to your internal services if you're concerned about security.

You're probably right. At one point, I had a subscription to homeassistant cloud a few years back to use a google nest speaker at the time. I was just going off that I guess. I'll do some testing and will probably put it back behind tailscale. thanks for the heads up

I'm more so concerned that I set something up incorrectly and would like to be made aware of it in the event someone else noticed

That's very specific to individual services
