CompTIA Security+ (SY0-601) — Question 572

Which of the following characteristics of tokenization explains how credit card information that is stored in a database is protected?

Answer options

• A. The fields are irreversible.
• B. Symmetric algorithms are used.
• C. Only authorized card holders have access.
• D. The data is relabeled.

Correct answer: D

Explanation

The correct answer is D because tokenization works by replacing sensitive credit card information with non-sensitive equivalents, thus relabeling the data. Options A and B are incorrect as they refer to different security principles that do not directly relate to how tokenization protects stored credit card information. Option C is also incorrect because it addresses access control rather than the method of data protection.
