Which of the following is the BEST method to mitigate the risk of an unauthorized employee viewing confidential data in a database''
Correct Answer: B
Implementing a data masking process is the best method to mitigate the risk of an unauthorized employee viewing confidential data in a database. Data masking is the process of replacing sensitive data with fictitious but realistic data, such as changing names, addresses, phone numbers, etc. Data masking protects the privacy and confidentiality of the data, while still allowing for testing, analysis, or training purposes. Implementing role-based access control, including sanctions in NDAs, and installing a DLP tool are also useful methods to reduce the risk of data exposure, but they are not as effective as data masking, which prevents the data from being accessed in the first place.
