After copying a sensitive document from his desktop to a flash drive, Joe, a user, realizes that the document is
no longer encrypted. Which of the following can a security technician implement to ensure that documents
stored on Joe’s desktop remain encrypted when moved to external media or other network based storage?
Whole disk encryption
Removable disk encryption
Database record level encryption
File level encryption
Encryption is used to ensure the confidentiality of information. In this case you should make use of file level
encryption. File level encryption is a form of disk encryption where individual files or directories are encrypted by
the file system itself. This is in contrast to full disk encryption where the entire partition or disk, in which the file
system resides, is encrypted.
