The Address Resolution Protocol (ARP) is vital for local network operations, enabling devices to map IP addresses to MAC addresses within a Local Area Network (LAN). By functioning at layer 2 of the OSI model, ARP ensures that devices can locate each other efficiently, preventing network paralysis. However, ARP is also susceptible to various vulnerabilities, presenting risks from bad actors. This article outlines the importance of ARP while also providing preventative steps to mitigate potential threats and maintain secure communications in local networks.
ARP is a crucial layer 2 communication protocol in local area networks, enabling devices to find each other through IP and MAC address mapping.
Despite its significance, ARP has vulnerabilities that can lead to unauthorized access and network exploitation if not properly managed.
