Question

What is the name of the IEEE standard for authentication to connect to a LAN (not just wireless)?

Answer 1

The name of the IEEE standard for authentication to connect to a Local Area Network (LAN), including wireless is, IEEE 802.1X, for Port-based Network Access Control (PNAC). It is one of the 802.1 group networking protocols. Its basic and main function is providing and enhancing security authentication framework and mechanism to devices such as wired and wireless clients, requesting to connect to a LAN or Wireless LAN (WLAN) or to other devices on these networks, where the clients or users are authenticated by a central authority. Its purpose is to either accept or reject users who require full access to a network using and following the IEEE 802.1x standard.

IEEE 802.1X is a standard for passing Extensible Authentication Protocol (EAP) over a wired such as a LAN or Wireless LAN (WLAN). This requires a responsive host with 802.1X authentication enabled and that provides authentication credentials such as a user name and a password. It thus, supports 802.1x authentication for wired and wireless users.
