Which method enhances security by requiring more than one form of verification?

• A. Single-factor authentication
• B. Biometric verification
• C. Multi-factor authentication
• D. Remote access systems

Answer: (C)

Multi-factor authentication enhances security by requiring more than one form of verification from the user. This method typically combines something the user knows (like a password), something the user has (like a smartphone or a security token), and something the user is (such as a fingerprint or facial recognition). By utilizing multiple verification factors, it significantly reduces the chances of unauthorized access, as an attacker would need to compromise multiple elements in order to gain access to a system or account. In contrast, single-factor authentication relies solely on one form of verification, such as just a password, making it less secure. Biometric verification, while it can be a significant component of multi-factor authentication, does not by itself guarantee the use of multiple forms of verification. Remote access systems refer to technologies that enable users to access systems from a distance but do not inherently specify the methods of authentication used. Thus, multi-factor authentication stands out as an effective approach to enhancing security through diverse validation methods.
