Detection and prevention of ARP poisoning in dynamic IP configuration

Nowadays security is a major concern. Address resolution Protocol (ARP) is a most popular communication protocol in the LAN. ARP is mapping from IP address (32 bits) into MAC address (48 bits). ARP has some limitations like lack of states and authentication. So attacker can exploit these vulnerabilities and gain unauthorized access to one's sensitive data. There are some attacks against ARP like MAC Spoofing, MAC duplicating, Man-in-the-middle (MITM) and denial of services (DOS). So efficient and secure scheme is provided which prevents ARP attacks. This paper demonstrates a utility which gives users the authentication as well as detection and prevention of ARP poisoning in dynamic IP configuration. Utility provides a mechanism which is based on internet control management protocol (ICMP) which uses secondary cache for checking pair entry of IP-MAC respective the system in the network.
