Your boss asks you to transmit a small file that includes sensitive personnel data to a server on the network. The server is run
mel-nik [20]

Answer:

a. Telnet transmissions are not encrypted.

Explanation:

Indeed, since <em>Telnet transmissions are not encrypted,</em> all the information sent, and even the characters typed in the telnet console are sent in clear text.

This is a security issue, since any other device in the same network will receive a copy of the information (packets) sent. For default, all the devices, except for the server expecting to receive the information, will discard the packets. However it is easy to actively <em>listen </em>and keep those packets, wich will contain the information in plain text and human readable.
