The concept of "defense in depth" emphasizes a layered security approach. This strategy involves implementing multiple layers of security controls throughout the IT environment, rather than relying on a single line of defense. By having various safeguards in place, such as firewalls, intrusion detection systems, antivirus software, and physical security measures, organizations can create a more resilient defense against potential security threats.

This multi-faceted approach ensures that if one layer is breached, additional layers remain in place to provide protection. It's designed to address various types of threats and vulnerabilities, allowing for a more comprehensive risk management strategy. Each layer serves as a barrier against attacks, and the combined effect of all layers working together enhances the overall security posture.

The other options do not align with the principle of defense in depth. A single point of security control can lead to vulnerabilities if that control is compromised. Minimal use of security measures is contrary to the concept of layering and would increase the risk of a successful attack. Focusing solely on endpoint protection neglects other critical areas of security, such as network defenses and data protection, which are essential components of a robust security strategy.
