B. New protocols often introduce unexpected vulnerabilities, even when developed with otherwise secure and tested algorithm libraries.

A security technician would like to obscure sensitive data within a file so that it can be transferred without causing suspicion. Which of the following technologies would BEST be suited to accomplish this?
A. Transport Encryption
B. Stream Encryption
C. Digital Signature
D. Steganography Answer: D
Explanation:
Steganography is the process of hiding a message in another message so as to obfuscate its importance.

You could encode your message in another file or message and use that file to hide your message.

B. A stream cipher was used for the initial email; a block cipher was used for the reply
