Your question is Driving Layered Security Under Constraints. 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 a time you had to improve a system’s security using a defense-in-depth approach when you could not fix everything at once. How did you decide which layers to strengthen first, how did you influence others to adopt the plan, and what was the outcome?
