12.3.3 - Enterprise Authentication

These flashcards cover key concepts related to enterprise authentication in networking, focusing on protocols, mechanisms, and security methods.

Enterprise Authentication

A method that uses IEEE 802.1X and Extensible Authentication Protocol (EAP) to authenticate users against a network directory.

IEEE 802.1X

A network protocol that provides an authentication mechanism to devices wishing to connect to a LAN or WLAN.

Extensible Authentication Protocol (EAP)

An authentication framework frequently used in wireless networks and point-to-point connections.

Supplicant

A wireless client device requesting to connect and authenticate to the network.

AAA Server

Authentication, Authorization, and Accounting server used to validate user credentials, such as RADIUS or TACACS+.

Master Key (MK)

A key transmitted from the AAA server to the supplicant after it has been authenticated, used to derive the Pairwise Master Key (PMK).

Pairwise Master Key (PMK)

A key derived from the Master Key, used by the wireless station and access point to generate session keys.

WPA2-Enterprise

A security method that provides enhanced security features for wireless networks, utilizing 802.1X for user authentication.

WPA3-Enterprise

The latest version of Wi-Fi Protected Access that enhances security protocols for enterprise networks.

EAPoW (EAP over Wireless)

Allows an access point to forward authentication data without granting any other type of network access.
