Certified Internal Auditor (CIA) Part 3: Business Knowledge for Internal Auditing — Question 91

Which of the following security controls would provide the most efficient and effective authentication for customers to access their online shopping account?

Answer options

• A. 12-digit password feature.
• B. Security question feature.
• C. Voice recognition feature.
• D. Two-level sign-on feature.

Correct answer: D

Explanation

The two-level sign-on feature enhances security by requiring two forms of authentication, making it more effective than the other options. A 12-digit password may still be susceptible to brute-force attacks, while security questions can often be guessed or researched. Voice recognition can be unreliable due to variations in speech and background noise.
