Explanation

Layered and comprehensive security countermeasures - often called defense in depth - are the industry standard because no single control is foolproof; if one layer fails, others remain to detect or contain the threat. A is wrong because relying solely on perimeter defenses (like firewalls) leaves an organization completely exposed once that perimeter is breached - modern attackers routinely bypass it. C is wrong because security through obscurity (hiding how a system works instead of actually securing it) is widely discredited; once the secret is discovered, protection collapses entirely. D is wrong because aesthetics have no bearing on security effectiveness - a beautiful interface with weak controls is still insecure.

Memory tip: Think of it like a medieval castle - walls, a moat, guards, locked doors, and a keep inside. That's layers. One wall alone never protected a kingdom.
