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!
Never used it “in anger” but:
I have my firewall plugged into a metered outlet (plugged into a UPS). I have it set up to send me alerts if power draw increases beyond a certain threshold. I’ve tested it and wireguard is measurable (yay) but so are DDOS attacks. If I get that alert, I can choose to turn off that plug and take my whole network offline until I get home and can sort that out.
Gotten a few false positives over the years but mostly that is just texting my partner to ask what they are doing.
Aren’t you just DoSing yourself at that point?
