Every since the OPM hack of 2015, I've been apparent to me that my former field of IT administration has lost the plot. Nobody knows what a data diode is, or why you would use one. Systems that should clearly be air-gapped aren't.
While it's easy to lay this at the feet of AI getting better at hacking. I see it as an primarily an IT issue. We've collectively ignored the lessons of history, and made do with patch jobs over poorly chosen operating systems instead.

We need air gaps, data diodes, and capability based operating systems. Now that I'm retired, when I have the energy, I'm working on the data diode part.
This weeks lesson for me, personally, as I try to build an open source data diode, is that the Waveshare RP2350-ETH is a horrible choice for a proxy/data source/sink, as the CH9120 ethernet interface can't do promiscuous mode. It might still be sufficient to build a data diode that can mirror a website, with << $50 component cost. Time will tell.
The systems that nobody will test, and indeed which nobody will instrument. Here's a DNS data diode for Redis: <a href="https://github.com/m3047/rkvdns" rel="nofollow">https://github.com/m3047/rkvdns
