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.
