Section: Compliance and Operational Security

Steganography is the process of hiding one message in another. Steganography may also be referred to as electronic watermarking. It is also the process of hiding a message in a medium such as a digital image, audio fi le, or other fi le. In theory, doing this prevents analysts from detecting the real message. You could encode your message in another file or message and use that file to hide your message.

Incorrect Answers:
A: Social engineering is the process by which intruders gain access to your facilities, your network, and even your employees by exploiting the generally trusting nature of people. A social engineering attack may come from someone posing as a vendor, or it could take the form of an email from a (supposedly) traveling executive who indicates that they have forgotten how to log on to the network or how to get into the building over the weekend.
C: Hashing refers to the hash algorithms used in Cryptography.
D: Digital Signatures is used to validate the integrity of the message and the sender.
