CompTIA Security+ (SY0-701) — Question 552

An organization that handles sensitive information wants to protect the information by using a reversible technology. Which of the following best satisfies this requirement?

Answer options

• A. Hardware security module
• B. Hashing algorithm
• C. Tokenization
• D. Steganography

Correct answer: C

Explanation

Tokenization is the correct choice because it replaces sensitive data with non-sensitive equivalents that can be reversed, allowing for data protection while maintaining usability. A Hardware security module provides secure key management but does not directly offer reversible data protection. A Hashing algorithm is a one-way function and cannot be reversed, while Steganography hides information but does not provide a method of data recovery in its original form.
