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!
The problem is, you’d expect your switch to mirror all traffic, including what it is generating (switches with web servers, baseband/backdoors like every big manufacturer), but you can never really be sure.
