Question 1 of 29
A financial services company is developing a new application that requires access to customer account information for testing purposes. The development team needs to ensure that sensitive data is not exposed during this process. Which data masking technique would be most appropriate for this scenario to maintain data integrity while protecting sensitive information?
Static data masking, which creates a separate copy of the database with masked data for development use.
Dynamic data masking, which alters the data in real-time based on user roles while allowing access to the original data.
Tokenization, which replaces sensitive data with non-sensitive equivalents but retains the ability to revert to the original data.
Data encryption, which secures data by converting it into a coded format that requires a key for access.
