摘要
The present invention relates to a method of defending against a spoofing attack using a blocking server, and more particularly, to a method of defending against a spoofing attack using a blocking server, which is characterized in that it involves inspecting an IP and MAC address included in an ARP packet received by a client in a network, and changing the addresses to a legitimate IP address and to a corresponding MAC address when the addresses are found to be used in a spoofing attack. According to the present invention, in the blocking of a spoofing attack against a network, an IP address and a MAC address for legitimate hardware connected to the network may be prestored and monitored, so as to exhibit the effect of an accurate defense being enabled in a short time.
