Brother, I need the "remedial" lessons since I self-host a lot of my experimental DNN solutions on a GPU cluster served via CasaOS/Ubuntu-Server LTS.
I've followed basic tutorials about nginx, end-to-end encryption, and DNS, but I need more knowledge and training about the theory behind modern security best practices. I think I'm doing okay but I have this ever-present anxiety that I've overlooked something and my ass (i.e., sensitive data) is really just hanging out in the wind.
Thank you for your recommendation.
