What does "Defense in Depth" primarily refer to in cybersecurity?

Layering defenses to provide added protection
A single robust security measure
Using a centralized defense mechanism
Eliminating the need for multiple defenses

The correct answer is: Layering defenses to provide added protection

"Defense in Depth" primarily refers to the strategy of layering multiple security defenses to provide comprehensive protection against potential threats. This approach acknowledges that no single security measure is foolproof and that relying solely on one method can leave vulnerabilities. By employing a variety of overlapping security measures – such as firewalls, intrusion detection systems, antivirus software, and physical security controls – organizations can create a more resilient defense posture. The idea is that if one measure fails, others will still be in place to safeguard against an attack. Each layer serves to slow down or stop an attacker, giving the organization additional time to respond effectively. This concept enhances overall security by ensuring that defenses function together strategically rather than in isolation.
