Your question is Security Concepts Review. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
Tell me about how you approach security concepts like secure boot and access control when building embedded systems on Arm.
Keep your answer focused on how you would reason about trust anchors, firmware verification, and privilege boundaries on Arm platforms. I am looking for practical trade-offs, failure modes, and how you would verify that the controls actually work.
