A security administrator discovers an image file that has several plain text documents hidden
in the file. Which of the following security goals is met by camouflaging data inside of other
files?
A.
Integrity
B.
Confidentiality
C.
Steganography
D.
Availability
C. Steganography is the process of concealing a file, message, image, or video within another file, message, image, or video.
Note: The advantage of steganography over cryptography alone is that the intended secret message does not attract attention to itself as an object of scrutiny.
Plainly visible encrypted messages, no matter how unbreakable will arouse interest, and may in themselves be incriminating in countries where encryption is illegal. Thus, whereas cryptography is the practice of protecting the contents of a message alone, steganography is
concerned with concealing the fact that a secret message is being sent, as well as concealing the contents of the message.
