ARP SPOOFING PROTECTING SYSTEM

摘要

PURPOSE: An address translation protocol spoofing prevention system is provided to automatically notify host information related to the modulation of ARP(Address Resolution Protocol) packet to an operator by monitoring ARP traffic. CONSTITUTION: Plural ARP protectors(10) periodically transmit and receive an IP(Internet Protocol) address and an MAC(Medium Access Control) address. The ARP protectors update ARP cache by collecting ARP information of other computers on a local network. The ARP protectors establish the updated ARP cache as a static mode. An ARP protector server(20) monitors ARP traffic. The ARP protector server detects the ARP protector which modulates the ARP packets from the ARP protector.
