Network sniffing

The first type of sensitive information traveling across the Internet is user name, password, and IP address combinations. These data are the primary targets of sniffer programs operated by Internet attackers. These are read by the sniffer program and typically recorded in a file intended to be retrieved later by the attacker. These combinations can then be used to break into the users account. and from there the attacker can compromise the entire system.A solution to this problem is to have these data sent across the Internet in a secure manner, such as by encrypting them first.
