Which of the following is a true statement pertaining to data encryption when it is used to protect data?

A.
It verifies the integrity and accuracy of the data.

B.
It requires careful key management.

C.
It does not require much system overhead in resources.

D.
It requires keys to be escrowed.

Explanation:
Data encryption always requires careful key management. Most
algorithms are so strong today that it is much easier to go after key management
instead of a brute force attack. Hashing algorithms are used for data integrity,
encryption does require a good amount of resources, and keys do not have to be
escrowed for encryption.
