CompTIA SecurityX (CAS-005) — Question 241

A company is looking for a solution to hide data stored in databases. The solution must meet the following requirements:

• Be efficient at protecting the production environment
• Not require any change to the application
• Act at the presentation layer

Which of the following techniques should be used?

Answer options

• A. Masking
• B. Steganography
• C. Algorithmic
• D. Random substitution

Correct answer: A

Explanation

Masking is the correct technique since it protects sensitive data without requiring changes to the existing application and operates at the presentation layer. Steganography, while it hides data, is not specifically designed for database protection. Algorithmic and random substitution methods may not meet the requirement of being efficient in the production environment.
