Learning ARP Spoofing Through Theory and Practice
Introduction ARP spoofing is an attack technique that has been studied in the network security field for a long time. This attack aims to intercept or modify network traffic by exploiting the structural limitations of the ARP protocol. In this article, we will systematically cover the basic concepts of the ARP protocol, the operational principles of ARP spoofing, actual attack implementation, and methods to defend against it. What is the ARP Protocol? ARP (Address Resolution Protocol) is a protocol responsible for address translation between the network layer (IP) and the data link layer (MAC). Simply put, to communicate on an IP network, you need to know not only the target’s IP address but also its MAC address. This is where ARP comes in. ...
