@ryangcox_: Secure system design is one of those skills that shows up everywhere in cybersecurity - interviews, architecture review meetings, and real-world engineering work. That’s why I added it as the newest skill inside DefendTheOrg. Instead of just talking about architecture, you actually design systems, place infrastructure, segment networks, and work through security tradeoffs the same way you would on the job. The goal isn’t memorization. It’s learning how to think through secure design decisions in practice. It’s live now - go try it out and let me know what you think!
