Which of the following are NOT a countermeasure to traffic analysis?

A.
Padding messages

B.
Eavesdropping

C.
Sending noise

D.
Covert channel analysis

Explanation:
Lets do this with a elimination process. With padding messages you can
countermeasure traffic analysis because you add garbage information to the message to let in end
in a fixed length, this can confuse the analyzer. Sending noise on the communication line could
also countermeasure analysis because the analyzer don’t now how to differentiate between real
information and noise. You can also covert channel analysis. Eavesdropping does not apply in this
situation, its not considered a counter measure to traffic analysis.
