User Passwords Sniffing and Defense in LANs

Abstract:

In this paper, the network security of LANs and the data sniffing theory is discussed. The sniffing and intercepting process of FTP and Telnet login usernames and passwords is described. Its not safe to transmit data in a network without encrypting any data. In order to keep important information safe, it is necessary to encrypt those important data before transmission, especially login usernames and passwords. SSH is a secure protocol used to make up for the defect of traditional TCP/IP protocols. By using SSH, the important messages such as login usernames and passwords can be encrypted. It is very difficult for a network attacker to retrieve the important messages even if he has captured those encrypted messages.
