What security method involves using different technological levels to protect the same assets?

The concept of using different technological levels to protect the same assets is best described by the principle known as "Defense in Depth." This strategy employs multiple layers of security controls (such as physical security, technical measures, and administrative policies) to provide redundancy and a more robust overall security posture. If one layer is compromised, there are additional layers in place to mitigate potential risks and protect the assets. This approach addresses vulnerabilities by ensuring that a single point of failure does not lead to a total compromise of security.

In contrast, layered security emphasizes more on the variety of security tools and measures, focusing on how they work together rather than outlining the strategic implementation of multiple distinct layers aimed at defense and redundancy which is specific to defense in depth. Access control pertains to the mechanisms that restrict unauthorized users from accessing resources, while incident response involves procedures for managing and responding to cybersecurity incidents. While all contribute to a comprehensive security strategy, Defense in Depth specifically targets the redundancy and layering aspect in asset protection.
