What term refers to the use of various layers of security controls to protect assets according to their level of risk?

The term that refers to the use of various layers of security controls to protect assets according to their level of risk is known as security-in-depth. This approach emphasizes that no single security measure is sufficient on its own, and instead advocates for implementing multiple layers of security to address various threats.

This multi-layered strategy ensures that if one security layer fails, others are still in place to provide protection. The primary goal is to create a comprehensive security posture that considers the varying levels of risk associated with different assets and environments. By customizing the layers of security based on the level of risk, organizations can more effectively safeguard their critical assets from a diverse range of threats.

Risk assessment refers to the process of identifying and evaluating risks, while layered security is often used synonymously with security-in-depth but does not specifically highlight the tailored approach based on risk levels. Asset protection generally focuses on safeguarding physical items or information more broadly, rather than the strategic, layered approach indicated in the question.
