CompTIA Security+ Question F-25

Which of the following is the BEST method for ensuring all files and folders are encrypted on all corporate laptops where the file structures are unknown?

A. Folder encryption
B. File encryption
C. Whole disk encryption
D. Steganography

Answer: C

Full-disk encryption encrypts the data on the hard drive of the device or on a removable drive. This feature ensures that the data on the device or removable drive cannot be accessed in a useable form should it be stolen. Furthermore, full-disk encryption is not dependant on knowledge of the file structure.
