Key Takeaway: IEEE 802.1X is an IEEE Standard for port-based Network Access Control using port authentication mechanisms. It provides an authentication mechanism to devices wishing to attach to a LAN, either establishing a point-to-point connection or preventing it if authentication fails. It is used for most wireless 802.11 access points and is based on the Extensible Authentication Protocol (EAP).
