== 802.1X Wired Authetication ==

802.1X is an IEEE standard that authenticates devices connecting to a network. It's a port-based network access control (PNAC) protocol that works for both wired and wireless devices. 

How it works :
* A device (supplicant) initiates a connection with the network. 
* The network device (authenticator) provides data links to connect the device to the network. 
* The authentication server receives the request for access and responds. 
* The authentication server verifies the device's identity using a certificate or MAC address. 
* The authentication server grants or denies access to the network. 

Security :
* 802.1X is secure, but it's not invulnerable.
* The security of the policies created for 802.1X is important.
* Weak policies, like requiring only a username and password, can be vulnerable to dictionary attacks.
* Session hijacking and man-in-the-middle attacks can also be effective.

Interoperability :
* Not all wired LAN components fully support 802.1X.
* This is especially true for older equipment and some newer IoT devices.
