An organization wants to ensure network access is granted only after a user or device has been authenticated. Which of the following should be used to achieve this objective for both wired and wireless networks?
… The great thing is that, while 802.1X is probably most seen on corporate wireless networks as the preferred form of authentication and access management control, it is not a wireless standard at all and can be used in wired networks as well. This actually makes it easier for wireless and wired networks to interoperate, since they can use the same authentication methods and can connect to each other quite easily. … (Mike Meyers’ CompTIA Security+ p. 331)
EEE 802.1X is an IEEE Standard for port-based Network Access Control (PNAC). It is part of the IEEE 802.1 group of networking protocols. It provides an authentication mechanism to devices wishing to attach to a LAN or WLAN.
IEEE 802.1x port-based network access control (PNAC) is a network authentication protocol that can integrate with RADIUS for remote access, and can use digital certificates to authenticate clients
