Which of the following can be used to ensure that sensitive records stored on a backend server
can only be accessed by a front end server with the appropriate record key?
A.
File encryption
B.
Storage encryption
C.
Database encryption
D.
Full disk encryption
I think it is C. When I hear “backend server” and “records” I think database. A database will not have entire files encrypted, only the “sensitive records.”

This is the second database encryption question that I have seen. Basically, full disk encryption is data at rest encryption (generally block level encryption). File level encryption means that the individual file is encrypted and once you have the key, you have access to the entire file. Database encryption is where the database administrator encrypts certain records or rows or columns to prevent people who have access to the database from viewing unauthorized areas. You have access to the file but not to all of the records in that database file. The catch words here are backend server (normally a database)–front end server is normally a webserver. As Nash denotes, records are also a database norm.
