SYSTEM AND METHOD FOR DETECTING ADDRESS RESOLUTION PROTOCOL (ARP) SPOOFING

摘要

There are provided a system and method for detecting Address Resolution Protocol (ARP) attacks. The ARP spoofing attack detection system includes: a reception module which receives an ARP packet, and which determines whether the received ARP packet is an unsolicited ARP packet; a transmission module which creates, if the ARP packet is an unsolicited ARP packet, an ARP request packet corresponding to the unsolicited ARP packet, and which broadcasts the ARP request packet; and a detection module which determines, if an ARP response packet corresponding to the ARP request packet is received, whether an input port of the ARP response packet is identical to an input port of the unsolicited ARP packet, and which determines that an ARP spoofing attack has occurred if the input port of the ARP response packet is not identical to the input port of the unsolicited ARP packet.

主权项

1. An Address Resolution Protocol (ARP) spoofing attack detection system, comprising:
a receiver which receives a first ARP packet, and which determines whether the received first ARP packet is an unsolicited ARP packet; a transmitter which creates, in response to the received first ARP packet being determined as an unsolicited ARP packet, an ARP request packet which corresponds to the unsolicited ARP packet, and which broadcasts the created ARP request packet; and a detector which determines, in response to an ARP response packet which corresponds to the broadcasted ARP request packet being received, whether an input port of the received ARP response packet is identical to an input port of the unsolicited ARP packet, and which determines that an ARP spoofing attack has occurred in response to the input port of the received ARP response packet being determined as not identical to the input port of the unsolicited ARP packet.
