Explanation:
“Traffic analysis and trend analysis are forms of monitoring that examine the flow of packets rather
than the actual content of packets. Traffic and trend analysis can be used to infer a large amount of

servers, primary and backup communication pathways, amount of traffic supported by the network,
typical direction of traffic flow, frequency of communications, and much more.” Pg 429 Tittel: CISSP
