Chapter 2, Problem 18RQ

Explanation of Solution

Sniffer attack:

In terms of network security, sniffer attack is a method of stealing the data or capturing the network packets with the help of sniffer. During the transmission of data across the network, it is necessary to encrypt the data packets because the data can be read using sniffer, if the data packets are not encrypted. With the help of sniffer application an attacker can easily gain the information in the network and then crash the network.

Steps that make sniffer attack a successful one:

• The attacker can gain access only after getting inside the network.
• The attacker gets the control over the device through the network...
