CompTIA CASP+ (CAS-004) — Question 130

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. Tokenization
• C. Algorithmic
• D. Random substitution

Correct answer: A

Explanation

Masking is the correct choice as it allows data to be hidden in a way that protects the production environment without requiring any changes to the application and functions at the presentation layer. Tokenization, while also a data protection technique, often requires changes to the application to handle tokens instead of original data. Algorithmic and random substitution methods do not specifically address the requirement of operating at the presentation layer effectively.
