CompTIA Security+ study material · question 251 of 611

A developer replaces sensitive identifiers with a reversible transformation and calls the data protected. What is the correct assessment?

• Secure design
• Cryptography

1. It is encrypted, so the data is protected
2. It is obfuscated, which makes it harder to read but does not make it secret
3. It is tokenised, so no sensitive value remains
4. It is hashed, so the original cannot be recovered
