What are the most paranoid network/OS security measures you've implemented in your homelab? (lemmy.world)

As the title says, I want to know the most paranoid security measures you've implemented in your homelab. I can think of SDN solutions with firewalls covering every interface, ACLs, locked-down/hardened OSes etc but not much beyond that. I'm wondering how deep this paranoia can go (and maybe even go down my own route too!).

Thanks!

Care to share what outlet you had success with? I'm comfortable with Home Assistant and ZigBee/Z-Wave. Something this critical probably shouldn't be wireless, but I digress. I'm also interested in what software you're using for monitoring and alerts (if you're willing to share). Cheers!

I just use a pretty generic z-wave plug and home assistant. In the past I did more complex setups that actually determine what process is spiking and so forth. But eventually realized that "this is doing a lot of compute..." is a catch all for a LOT of potential issues.

And I guess I don't understand what you mean by "shouldn't be wireless". It is inherently going to be wireless because you will be on your phone on the other side of the planet. If you genuinely suspect you will be vulnerable to attacks of this scale then you.... probably have other things to worry about.

But as a safety blanket?

Gotcha. A ZigBee/Z-wave plug was the first thing that came to mind. I'll probably go the same route. I was merely saying that wireless-anything is less dependable than wired. But I don't even know if wired smart plugs exist. I use wireless sensors around my home and I've never had an issue with dependability. I definitely wasn't considering Z-wave as a local attack vector. I was just brainstorming some way to avoid a wireless solution for something where dependability is paramount.
