What security strategy employs multiple measures to enhance overall defense?

Layered security is a strategy designed to enhance overall defense by implementing multiple, overlapping security measures. This approach recognizes that no single security control is sufficient to protect against all potential threats. Instead, it relies on a combination of physical, technical, and administrative controls working together to create a more resilient system.

By layering security, organizations can mitigate risks at various levels, such as through firewalls, intrusion detection systems, access control measures, and employee training. Each layer serves as an additional barrier against a potential breach, so if one security measure fails, others continue to provide protection. This concept aligns with the best practices in security management, where redundancy and diversity of security measures significantly increase the chances of thwarting an attack.

The other strategies mentioned, such as integrated, comprehensive, and modular security, may focus on different aspects of security management but do not specifically emphasize the concept of layering multiple defenses in the same way. Integrated security typically refers to combining various security systems and processes into a cohesive strategy, comprehensive security implies an all-encompassing approach without the explicit layering aspect, and modular security suggests using separate, interchangeable components rather than a structured layering of defenses. Hence, layered security stands out as the strategy most focused on enhancing defense through multiple protective measures.
