CompTIA Security+ (SY0-701) — Question 84

A company must ensure sensitive data at rest is rendered unreadable. Which of the following will the company most likely use?

Answer options

• A. Hashing
• B. Tokenization
• C. Encryption
• D. Segmentation

Correct answer: C

Explanation

Encryption is the most appropriate method for rendering sensitive data unreadable at rest, as it transforms the data into a format that cannot be easily interpreted without the correct decryption key. Hashing is a one-way function primarily used for data integrity, while tokenization replaces sensitive data with tokens but does not render the data itself unreadable. Segmentation involves separating data but does not inherently protect it from being readable.
