You have been hired to perform a penetration test on a client’s network. You want to see if remote connections are susceptible to eavesdropping or perhaps session hijacking. Which network tool would be most helpful to you?

A.
Vulnerability analyzer

B.
Port scanner

C.
Performance analyzer.

D.
Protocol analyzer

Explanation:
A protocol analyzer allows you to view a network conversation and to see the text in English. If the conversation is not encrypted a protocol analyzer will quickly discover this vulnerability. Answer option B is incorrect. A port scanner can be used to find vulnerable ports and services, but not weaknesses in remote connections.
