Media Access Control

Definitions

1. The data-link layer mechanism and addressing scheme used to identify network interfaces on local networks, commonly abbreviated MAC in Ethernet and Wi-Fi contexts. In security discussions, media access control appears in topics such as MAC addresses, filtering, spoofing, and switch behavior.

   In plain English: The network addressing mechanism used to identify devices on a local link.

   Example: "The wireless controller tracked device moves by media access control address, though that was not enough for strong identity on its own."
