Multi-factor Authentication (MFA) significantly enhances security by requiring users to present multiple forms of verification when logging into an account or system. MFA typically involves a combination of something the user knows (like a password), something the user has (like a smartphone or hardware token), and something the user is (like biometrics, such as a fingerprint or facial recognition). This layered approach makes it much more difficult for unauthorized individuals to gain access, as compromising only one of these factors is usually insufficient to bypass the security measures in place.

In contrast, other options focus on different aspects of security but do not primarily enhance user verification. Single Sign-On allows users to access multiple applications with one set of credentials, which simplifies user experience but doesn't inherently provide additional verification methods. Data Encryption protects the confidentiality of data both at rest and in transit, ensuring that intercepted data remains unreadable, but it does not enhance the verification process for users. Network Monitoring identifies and tracks activities on a network to detect and respond to threats, but it doesn’t influence the process of verifying the identity of users. Hence, Multi-factor Authentication is distinctly focused on bolstering user identity verification, making it the correct choice.
