What security approach involves using multiple overlapping methods to secure an environment?

The correct answer is layered defenses. This security approach emphasizes applying multiple security measures that work together to protect an environment. Each layer provides a different type of protection, which makes it more difficult for attackers to breach the system. If one layer fails, other layers are still in place to help mitigate risks and enhance overall security. This concept is fundamental in cybersecurity because it acknowledges that relying on a single method of security is often insufficient to protect against diverse and evolving threats.

Layered defenses could include a combination of technologies and practices, such as firewalls, intrusion detection systems, encryption, and access controls. By implementing these overlapping methods, organizations create a more resilient security posture that can adapt to various attack vectors and vulnerabilities.

The other approaches listed do not fully capture the essence of using multiple overlapping security methods. Mitigation refers to reducing the severity of risks but does not inherently involve multiple layers. Masking typically deals with obscuring specific data points rather than securing the entire environment. Multifactor Authentication enhances security by requiring multiple forms of verification for access but is just one element of a broader layered defense strategy.
