CompTIA Security+ (SY0-701) — Question 569

Which of the following solutions would most likely be used in the financial industry to mask sensitive data?

Answer options

• A. Tokenization
• B. Hashing
• C. Salting
• D. Steganography

Correct answer: A

Explanation

Tokenization is the process of replacing sensitive data with unique identifiers called tokens, making it a preferred method in the financial industry for data protection. Hashing and salting are primarily used for securely storing passwords rather than for masking sensitive data. Steganography hides information within other data, which is not specifically used for masking sensitive data in financial contexts.
