A place to share alternatives to popular online services that can be self-hosted without giving up privacy or locking you into a service you don't control.

Rules:

  1. Be civil: we're here to support and learn from one another. Insults won't be tolerated. Flame wars are frowned upon.

  2. No spam posting.

  3. Posts have to be centered around self-hosting. There are other communities for discussing hardware or home computing. If it's not obvious why your post topic revolves around selfhosting, please include details to make it clear.

  4. Don't duplicate the full text of your blog or github here. Just post the link for folks to click.

  5. Submission headline should match the article title (don’t cherry-pick information from the title to fit your agenda).

  6. No trolling.

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"

What about home assistant? Me and the Family quite often use the HA app on the go, sometimes even from other computers like at my parents or in a hotel to check on the house and the cat. I also gave my dad access to it so he can see if we're at home and things like that.

Same with my dads HA.

Set up a VPN to get back inside your network if you're outside it. Then you don't need HA (or anything else for that matter) to be public.

HA had 2 security audits. I would not worry too much. Always depends on what you can control with it. https://www.home-assistant.io/blog/2023/10/19/security-audits-of-home-assistant/
