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"

By not making them publicly accessible. With Wireguard there's really no reason.

Setup service to be active on a subnet, enable Wireguard to VPN into the subnet and use the services.

Well, that's kinda of a personal choice. If somebody needs to have services accessible by someone else besides him, that service can't be behind a VPN (let's face the truth: we know that we can't ask all out relatives and friends to use a VPN).
