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!
Using SPA firewall knocking (fwknop) to open ports to ssh in. I suppose if I was really paranoid, the most secure would be an air gap, but there’s only so much convenience I’ll give up for security.
I’m going to save your comment because it has opened up a new technique for network security that I had never thought of before. Thanks a bunch
