CompTIA Security+ (SY0-701) — Question 399

An audit reveals that cardholder database logs are exposing account numbers inappropriately. Which of the following mechanisms would help limit the impact of this error?

Answer options

• A. Segmentation
• B. Hashing
• C. Journaling
• D. Masking

Correct answer: D

Explanation

Masking is the correct answer because it involves obscuring sensitive data to prevent unauthorized access while still allowing necessary operations. Segmentation, hashing, and journaling do not specifically address the issue of exposing account numbers in logs, making them less effective in this scenario.
