That is an excellent explanation of the different types of security controls. You did a great job clearly describing each category and showing how they all work together to protect an organization. I like how you pointed out that administrative controls focus on people and policies, technical controls rely on technology, and physical controls deal with securing the actual equipment and buildings. Your mention of defense in depth was also a strong point because it highlights how combining these layers creates a much stronger and more complete security system. Overall, your response shows a deep understanding of how organizations can protect their data and systems from many different types of threats.
