영문 초록

Current heavy Internet service traffic has caused serious problems in DNS services. For example, DNS Cache Poisoning which currently gets international attention is produced by DNS protocol itself which weaken from data forgery and alteration attacking. DNS has a responsibility to changing IP address and domain name, and it is very important tasks in Internet. However, even secure DNS server can be overloaded by spoofing which repeatedly heavy connects DNS server from attacking purposes. With the reasons, users can be unintentionally serviced by the altered DNS information and this can cause Pharming which can use the user s personal information illegally. In this paper, firstly we discuss the weakness of DNS Cache Poisoning and secondly we analyze the processing time of Kerberos authentification system which affected from DNS Cache Poisoning.
