Which of the following types of encryption will help in protecting files on a PED?

A.
Mobile device encryption

B.
Transport layer encryption

C.
Encrypted hidden container

D.
Database encryption

Explanation:
Device encryption encrypts the data on a Personal Electronic Device (PED). This feature ensures that the
data on the device cannot be accessed in a useable form should the device be stolen.
Incorrect Answers:
B: The transport layer provides network communication. It does not involve files on a Personal Electronic
Device (PED).
C: Encrypting hidden containers would protect the files in those containers. It will not protect the rest of
the files on the Personal Electronic Device (PED).
D: Database encryption makes use of cryptography functions that are built into the database software to
encrypt the data stored in the data base. 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. However, a database would typically be stored on a server and not a Personal
Electronic Device (PED).
