How can multi-factor authentication contribute to insider threat prevention?

Multi-factor authentication (MFA) significantly enhances security by requiring users to provide two or more verification factors to gain access to a system or data. This approach is particularly effective in preventing insider threats, as it adds layers of security that make it more challenging for unauthorized individuals—even if they have a password—to access sensitive information.

By mandating a combination of something the user knows (like a password), something the user has (such as a smartphone app that generates a one-time code), or something unique to the user (like a fingerprint), multi-factor authentication mitigates the risks associated with password theft or misuse. This multifaceted approach complicates the access process for potential insiders looking to exploit their legitimate access for malicious purposes, thereby acting as a strong deterrent against unauthorized access.

The other choices do not contribute to insider threat prevention in the same way. Making access easier or relying on single password usage weakens security. Eliminating the need for two-step verification compromises the primary strength of MFA, which is its requirement for multiple forms of verification to bolster security.
