CompTIA Security+ (SY0-701) — Question 372

An accountant is transferring information to a bank over FTP. Which of the following mitigations should the accountant use to protect the confidentiality of the data?

Answer options

• A. Tokenization
• B. Data masking
• C. Encryption
• D. Obfuscation

Correct answer: C

Explanation

Encryption is the most effective method for protecting data confidentiality during transfer, as it scrambles the data so that only authorized parties can read it. Tokenization and data masking alter the data but do not provide true confidentiality, while obfuscation makes the data less understandable but does not secure it against unauthorized access.
