Question

Your boss asks you to transmit a small file that includes sensitive personnel data to a server on the network. the server is running a telnet server and an ftp server. why is it not a good idea to use telnet to reach the remote computer?

Answer 1

If an attacker can see transmitted packets, they will be able to see login credentials and be able to log in to the server. Additionally, the sensitive data in the file will be visible to the attacker. A better way would be to transfer the file using sftp or tftp.
