Which of the following does full disk encryption prevent?

A. Client side attacks
B. Clear text access
C. Database theft
D. Network-based attacks


Correct Answer: B
Section: Application, Data and Host Security

Explanation:
Full-disk encryption encrypts the data on the device. This feature ensures that the data on the device cannot be accessed in a useable form should the device be stolen.

Incorrect Answers:
A, D: Full-disk encryption encrypts the data on the device itself and ensures that the data on the device cannot be accessed in a useable form should the device be stolen. It does not
prevent client-side or network-based attacks.
C: Full-disk encryption encrypts the data on the device itself. It may help prevent access to database data but database encryption would be the preferred method of protecting
database data.
