What does the concept of 'layered defense' aim to achieve?

The concept of 'layered defense' aims to achieve multiple barriers against different threats. This approach enhances security by creating various protective layers that work together to mitigate risks. Layered defense recognizes that no single security measure is foolproof; therefore, it seeks to combine different types of defenses, such as physical security measures, technological solutions, and procedural safeguards. This redundancy allows organizations to address a wide range of threats effectively, as if one layer is compromised, others remain intact to provide continued protection. By implementing various layers, a more resilient security posture is established, making it significantly harder for intruders to succeed.

In this context, while enhanced monitoring capabilities and simplification of security protocols could be elements of a security strategy, they do not fully capture the essence of a layered defense approach focused on building multiple barriers. Similarly, a single point of failure contradicts the very principle of layered defense, as it highlights vulnerability in security systems rather than reinforcing protection.
