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!

    • Custom Router/Firewall running OPNsense and the Sensei plugin
    • Extensive DNS filtering through Pihole
    • Redirecting all DNS requests to my Pihole through OPNsense
    • My entire network is behind a multi hop VPN
    • I don’t let any Windows systems connect to the internet, instead, I have a Linux server which is connected to the internet (through a VPN of course) and runs a browser, and I use X2go to access the browser which is running on the Linux server

      Since you’re running x86 for your router, do you actively prevent ME from trying to connect to the Internet?

        I am aware of the ME, but I can’t really do anything about it. Current ARM SBCs are not suitable for a router/firewall (at least in my experience). I’m not that concerned about it though.

          OpenWRT isn’t half bad for usual “router stuff”, but advanced usage is a bit hard to do. Of course, that doesn’t eliminate the problem since ARM can have plenty of backdoors too

            I know, I tried OpenWRT on a Pi, but the experience wasn’t great (at least not as a home router).

      Wouldn’t that last bullet mean you’re not updating the windows machines whatsoever? Would this not cause more security issues in the long run, considering “connected tot he internet” isn’t a requirement to spread an infection.

        It might sound ridiculous, but I currently also run a WSUS server to get Windows updates. But I will probably replace my entire Windows setup with a better solution. Since I don’t run Windows bare-metal anymore, I’m looking forward to using offline Windows VMs on my Proxmox host and just accessing the internet directly from my Linux machine.
