Which security concept allows only authorized individuals to access network resources using a combination of something you know, something you have, and something you are? Group of answer choices a ) Confidentiality b ) Zero Trust c ) Availability d ) Multifactor Authentication

Answer

What is Multifactor Authentication (MFA)?

🔐 Which Security Concept Uses Something You Know, Have, and Are?

✅ Correct Answer: d) Multifactor Authentication (MFA)

Multifactor Authentication (MFA) is a security mechanism that ensures access is granted only to authorized users by requiring them to present multiple forms of verification. It enhances security by combining at least two of the following categories:

🔑 Something you know: A password, PIN, or security question.
📱 Something you have: A smartphone, hardware token, or security key.
🧬 Something you are: Biometrics like fingerprints, facial recognition, or iris scan.

      🚀 MFA significantly reduces the risk of unauthorized access, even if one of the credentials is compromised.
    

🔒 Why Is MFA Important?

With the rise of cyberattacks and identity theft, relying solely on passwords is no longer sufficient. MFA provides a layered defense, making it exponentially harder for attackers to gain access.

Even if a hacker steals your password (something you know), they would still need access to your device or biometric data to complete authentication.

🚫 Why Other Options Are Incorrect

a) Confidentiality: Refers to ensuring information is not disclosed to unauthorized parties, but it doesn’t specify authentication methods.
b) Zero Trust: A broader security framework that assumes no implicit trust, requiring verification at every stage—but it’s not limited to MFA.
c) Availability: Ensures that systems and data are accessible when needed, not about verifying identity.

✅ Only Multifactor Authentication directly incorporates the combination of what you know, what you have, and what you are.

🔄 Summary

🔐 MFA adds an extra layer of security beyond just a password.
👤 It verifies identity using multiple factors.
🛡️ It’s one of the most effective ways to prevent unauthorized access.

🎯 Multifactor Authentication is a cornerstone of modern cybersecurity strategies — ensuring that even if one factor is compromised, your accounts and data remain protected.
