What is a key advantage of implementing security in depth?

Implementing security in depth is fundamentally about creating multiple layers of protection to safeguard assets and information. This strategy acknowledges that no single security measure is entirely foolproof; therefore, by layering various security mechanisms, it becomes significantly more challenging for an adversary to penetrate through all the defenses.

Each layer can serve a different function, from physical barriers and access controls to surveillance and monitoring systems, thereby mitigating risk at various points. For instance, if one security measure is compromised, subsequent layers can still provide protection, which enhances overall security resilience. This multitiered approach also allows organizations to implement targeted responses based on the specific risks identified at each layer.

While other options may address aspects of security strategies, none encapsulates the essence and primary advantage of the security in depth philosophy as effectively as the concept of offering multiple layers of protection.
