Which term denotes security requiring more than one verification method?

• A. Identity Assurance
• B. Proactive Security
• C. Multifactor Authentication
• D. Automated Provisioning

Answer: (C)

Multifactor authentication denotes security requiring more than one verification method, typically combining factors from different categories such as something you know, something you have, and something you are. This approach strengthens protection because even if one factor (like a password) is compromised, a second factor is still needed to prove the user’s identity, making unauthorized access significantly harder. In CIAM contexts, MFA is a common, effective control for safeguarding accounts and sensitive resources by reducing the risk of credential theft. Identity Assurance is about validating that an identity is trustworthy, but it doesn’t specify multiple verification steps at login. Proactive Security describes a broad approach to anticipating threats, and Automated Provisioning relates to automatically creating and managing user accounts and access rights, not the method of authentication.
