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 agree with WG however I need https for a few locally hosted items like actual budget so I have that through nginx proxy manager. I was debating adding Authelia in front with some of my others (audiobook shelf, home assistant and music assistant) as sometimes I disconnect from my home network and forget to reconnect.

Why not swap from nginx-proxy-manager to Caddy2, which can handle everything? SSL and reverse_proxy?

Just out of curiosity, why do you disconnect from your home VPN?

There should be an option in your phone VPN setup to reconnect if app X is being used.

There is. It's called VPN Split Tunneling.

If you want to proxify your connection between you and a service, you enable the split. If you don't care, or want to not use the VPN, then disable it for that application. So it's effectively "proxify all connections to this app," which is the same as your use case.
