IEEE 802.1X is an IEEE Standard for port-based Network Access Control (PNAC). It provides an authentication mechanism to devices wishing to attach to a LAN or WLAN. The standard defines a point-to-point protocol between a supplicant and an authenticator. Both of these components may be embedded in a networking device such as a wireless access point (AP) or a network switch. The supplicant is any device that wants to authenticate to the network, such as a laptop, smartphone, or tablet. The authenticator acts like a gatekeeper, allowing only authenticated devices access to the network.
