(English Abstract)
DNS spoofing is an attack in which an attacker intervenes in the communication between client and DNS server to deceive DNS server by responding to a fake IP address rather than actual IP address. It is possible to implement a pharming site that hacks user ID and password by duplicating web server¡¯s index page and simple web programming. In this paper we have studied web spoofing attack that combines DNS spoofing and pharming site implementation which leads to farming site. We have studied DNS spoofing attack method, procedure and farming site implementation method for portal server of this university. In the case of Kyungsung Portal, bypassing attack and hacking were possible even though the web server was SSL encrypted and secure authentication. Many web servers do not have security measures, and even web servers secured by SSL can be disabled. So it is necessary that these serious risks are to be informed and countermeasures are to be researched.
