If you are interested in helping the US Government fix this particular trashfire, consider joining the Defense Digital Service. We work on a variety of DoD projects as part of the US Digital Service "tech peace corps". https://www.dds.mil/ If you're not ready for that level of commitment (though it's amazing work), and you're interested in being involved as a security researcher, reach out to me and we can talk about…
1.) Does DDS really pen test developmental/operational weapon systems? I'm talking about custom flavors of standalone PIT systems at the lowest embedded level, not just public-facing unclassified commidity IT systems. Maybe I'm missing something, but the projects highlighted on DDS's website suggest otherwise.
2.) How's your Blue team ops? The current RMF meta in the field strikes me as an all-Red team party, while the Blue side of business is pretty much always MIA. I suspect it's partly because pen testing is fashionable these days, successful outcomes can be quite dramatic and perceivably understood by stakeholders, and avoidance of the inherent liablility of defensive posturing without significant impact to performance/capability if a complex system's requirements are not well understood (a compounded issue not exclusive to weapon systems), to name a few.
