If we notice a change in any of these mappings in future ARP traffic then we raise an alarm and conclude that an ARP spoofing attack is underway. In Passive Detection we sniff the ARP requests/responses on the network and construct a MAC address to IP address mapping database. There are two techniques for detecting ARP spoofing one is Passive technique and other is Active technique. So ARP spoofing attack is becoming the most dangerous attack in the LAN. With a DoS attack, the attacker makes a victim host deny communicating with others. With a MiM attack, the attacker can sniff the traffic between two victim hosts. Obviously, ARP protocol plays a key role in local area network communication, but due to its own loopholes, it is often used as part of other serious attacks such as Man-in-the- Middle (MiM) attack, Denial of Service (DoS) attack. And only the host with corresponding protocol address sends a unicast reply to the sender with its pair. When a host wants to communicate with another host whose hardware address it does not know, it broadcasts an ARP request for the hardware address associated with the protocol address of the destination. Internet Protocol (IP) address to physical address or Media Access Control (MAC) address. Its been working at network layer for the important dynamic conversion of network address i.e. KeywordsARP cache ARP protocol ARP spoofing libpcap dsniff ICMP protocolĪddress Resolution Protocol (ARP) is a protocol having simple architecture and have been in use since the advent of Open System Interconnection (OSI) network architecture. The technique includes collecting and analyzing the ARP packets, and then injecting ICMP echo request packets to probe for malicious host according to its response packets. On these bases, the paper proposed an efficient algorithm based on ICMP protocol to detect malicious hosts that are performing ARP spoofing attack. This paper discusses ARP spoofing attack and some related works about it first. ARP spoofing is the act of vindictively changing the IP- MAC associations stored in ARP cache of any network host.
