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!

I'm a Nixos user, I wouldn't be much help unless you do Nixos. But it's a whole new rabbit hole which would take you months/years to learn and setup 😅

What I can say, you can do "access from home network", "access from VPN network", "1fa/2fa from the internet" OR "access for / and /api, but 1fa/2fa for stuff like /admin, /admin-settings, or just /login or /logged-in"

Fail2ban is fun, also maybe have a look at crowdsec

    Ah, yeah, I'm running Proxmox. And I'm definitely seeing I have a lot of research to do before I open up to the internet!

    I'm actually not from the "close everything, don't open ports, always sit behind cloudflare" camp

    We selfhost so we can use and share our services

    There are other things we can practice instead of just isolationism and keeping everything as simple as possible
