Welcome to your interview.
The question is on your right: Securing ICS Without Downtime. Take a moment with it first.
Talk your thinking through with me if you like - when you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes). Discussion and graded submissions share your five interviewer interactions, so spend them well.
How do you secure an industrial control system (ICS) network from external cyber threats without disrupting operations?
