CompTIA Security+ (SY0-701) — Question 607

Which of the following is used to conceal credit card information in a database log file?

Answer options

• A. Tokenization
• B. Masking
• C. Hashing
• D. Obfuscation

Correct answer: B

Explanation

Masking is the correct answer because it specifically alters the data to hide sensitive information while allowing the format to remain intact. Tokenization replaces the sensitive data with non-sensitive equivalents, while hashing transforms data into a fixed-size string, making it irreversible. Obfuscation, while it can hide information, does not specifically focus on credit card details.
