What is 802.1x?
802.1x is actually a standard to enhance the security of wireless local area networks that follow the IEEE 802.11 standard. It uses the Entensible Authentication Protocol(EAP) that is used for message exchange during the authentication process. This feature is mostly used in enterprise network for better security.
