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?
Correct Answer: A
Masking is a technique for obscuring sensitive data in a database by replacing it with fictitious data that has the same format and structure as the original data. Masking can be performed at the presentation layer, which means that it does not require any changes to the application itself.
This makes it an efficient solution for protecting the production environment, as it can be easily implemented without disrupting the existing system.
Tokenization is a technique for replacing sensitive data with a randomly generated value (a token) that has no intrinsic meaning and cannot be used to recreate the original data.
Tokenization can be used to protect data at the presentation layer, but it typically requires changes to the application to store and retrieve the tokens.
