Which of the following types of data encryption would Matt, a security administrator, use to encrypt a
specific table?

A.
Full disk

B.
Individual files

C.
Database

D.
Removable media

Explanation:
A table is stored in a database. Database encryption makes use of cryptography functions that are built
into the database software to encrypt the data stored in the database. This often offers granular
encryption options which allows for the encryptions of the entire database, specific database tables, or
specific database fields, such as a credit card number field.
Incorrect Answers:
A, D: Full-disk encryption encrypts the data on the hard drive of the device. It can also be applied to
removable media. This feature ensures that the data cannot be accessed in a useable form should the
device or removable media be stolen or misplaced.
B: File-level encryption would involve encrypting the entire database file rather than a table in the
database.
