CompTIA CySA+ (CS0-002) — Question 146

Which of the following techniques can be implemented to safeguard the confidentiality of sensitive information while allowing limited access to authorized individuals?

Answer options

• A. Deidentification
• B. Hashing
• C. Masking
• D. Salting

Correct answer: C

Explanation

Masking is the correct choice because it allows sensitive information to be obfuscated while still enabling authorized users to access necessary data. Deidentification removes personal identifiers but may not allow for limited access, while hashing and salting are primarily used for data integrity and security rather than controlling access.
