ABSTRACT
This chapter presents a mechanism to defend man-in-the-middle (MITM) attack in the wired link. MITM attack is an attack where an adversarial computer secretly relays and possibly alters the communication between two computers that believe they are directly talking to each other via a private connection. The conventional approaches to defeat an MITM attack are quite specific to the techniques the hacker uses, a fact that makes the entire system more complicated and vulnerable to new hacking strategies. The chapter considers deep Q-network algorithm to handle the problem of an MITM attack. An MITM attack usually happens inside a local area network, the routing can narrow down to the intradomain routing protocols including the Routing Information Protocol. If the packet suffers from the MITM attack during the forwarding process, that is, passing through an intruded node, the controller will receive a relatively large penalty.
