Detection and Prevention of ARP Spoofing using Centralized Server

The Address Resolution Protocol (ARP) due to its statelessness and lack of an authentication mechanism for verifying the identity of the sender has a long history of being prone to spoofing attacks. ARP spoofing is sometimes the starting point for more sophisticated LAN attacks like denial of service, man in the middle and session hijacking. In a current voting based method an active technique is used for finding out the legitimate one by collection of voting’s from the neighboring host. The drawback of this system is most of the host in a LAN must follow the MR-ARP protocol. In this paper a centralized server will collects all the ip-mac pairs of every host in the LAN and maintains a table of legitimate host. Destination host checks the ip-mac conflict in the LAN and informs about the hacker to the centralized server which takes care of the trusted communication between the participating hosts. Hence, the proposed work detection and prevention of ARP spoofing lead to appreciable result
