I think my job requires me to work in too many different areas. So although I can work in several languages and dev stacks, I am probably only a 2 or 3 or less out of 5 in all of them. However, network and server infrastructure, and cybersec/opsec I am probably more in the realm of a 4-4.5.
I would totally be down for this. I am currently reading zero trust networks (2nd edition), but this is mainly due to the company I am working for looking to open up some web apps to the public internet. I am also reading Net Zeros and Ones to look more at data sanitizing.
Then fun reading is 2001 a space Odyssey.
