Certified Cloud Security Professional (CCSP) — Question 100

What strategy involves replacing sensitive data with opaque values, usually with a means of mapping it back to the original value?

Answer options

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

Correct answer: C

Explanation

Tokenization is the correct answer because it specifically refers to the process of replacing sensitive data with tokens that can be mapped back to the original values. Masking, anonymization, and obfuscation do not retain the ability to revert to the original data in the same way that tokenization does.
