Research on an Algorithm of Active Detecting and Resisting ARP Attack

To withstand the ARP attacks,an algorithm using an active technique to detect the ARP attacks was proposed.According to the algorithm,header of all ARP packets that the host receives and sends is detected,and the ARP packets of Inconsistent-Header are abandoned.Adopting the method of active detecting,the special packets are constructed using the address information in the ARP packet and sent to the host whose authenticity is to be verified,and thus the ARP packet is rejected if the host can't pass the authentication.In accordance with the rule of receiving ARP reply after sending an ARP request,the ARP reply without request is refused.The algorithm is faster and more reliable in detecting ARP attacks against the local host than other solutions against ARP attacks.Moreover,it can prevent local host from attacking other host and resists the ARP attacks more effectively.
