CompTIA Security+ (SY0-701) — Question 118

An organization wants to limit potential impact to its log-in database in the event of a breach. Which of the following options is the security team most likely to recommend?

Answer options

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

Correct answer: B

Explanation

Hashing is a technique that transforms sensitive data into a fixed-size string of characters, which is not reversible, thereby protecting the original data even if the database is compromised. Tokenization, obfuscation, and segmentation may have their own benefits, but they do not provide the same level of protection for the integrity of the data stored in the log-in database as hashing does.
