Abstract: In this paper we describe two novel methods for active detection and prevention of ARP-poisoning-based Man-in-the-Middle (MitM) attacks on switched Ethernet LANs. As a stateless and inherently insecure protocol, ARP has been used as a relatively simple means to launch Denial-of-Service (DoS) and MitM attacks on local networks and multiple solutions have been proposed to detect and prevent these types of attacks. MitM attacks are particularly dangerous, because they allow an attacker to monitor network traffic and break the integrity of data being sent over the network. We introduce backward compatible techniques to prevent ARP poisoning and deal with sophisticated stealth MitM programs.
