The primary objective of Cyber Security is to protect data in transit. If a network is vulnerable at layer two, the good fortune opens wide up for an attacker. With the easy availability of refined offensive tools that can exploit these vulnerabilities to create havoc in networks, there is a dire need of mitigative measures that can cope up with increasing threats. ARP Protocol violation is among the most hazardous onslaughts in the wireless networks today. This paper is an effort to implement the mechanism of ARP poisoning and its mitigation by enabling DHCP Snooping and Dynamic ARP Inspection. The attack has been demonstrated under test environment using Cain & Abel, Wireshark and NetworkMiner tools because of their merits. The paper also describes the mechanism of Dynamic ARP Inspection to mitigate man-in-the-middle attacks.
