Explanation

Defense in depth is a layered security strategy borrowed from military doctrine, where multiple independent security controls (firewalls, IDS, access controls, encryption, training, etc.) are stacked so that if one layer fails, others remain. It does not prioritize physical over digital security, does not rely on a single layer (that would be the opposite), and is proactive rather than purely reactive. The layered approach ensures no single point of failure can compromise the entire system.
