Securing network connections 39 Securing network connections Configuring 802.1X authentication Though normally associated with wireless devices and connectivity, 802.1X authentication supports both wired and wireless environments. 802.1X is located within the wireless menu when wireless is enabled on the device. The following network authentication mechanisms can be included in the 802.1X protocol negotiation: • EAP‑MD5 • EAP‑TLS • EAP‑TTLS with the following methods: - CHAP - MSCHAP - MSCHAPv2 - PAP • EAP_MSCHAPV2 • PEAP • LEAP Use EAP‑MD5 EAP‑TLS EAP‑TTLS PEAP (TLS) LEAP To Require a device login name and password. Require a device login name and password, CA certificate, and signed device certificate. Require a device login name and password, and CA certificate. Require a device login name and password, CA certificate, and signed device certificate. Require a device login name and password. Note: Make sure that all of the devices participating in the 802.1X process support the same EAP authentication type. 1 From the Embedded Web Server, click Settings > Security > 802.1x. 2 Under 802.1x Authentication, do the following: a Select Active to enable 802.1X authentication. b Type the login name and password the printer uses to log in to the authentication server. c Select the Validate Server Certificate check box to require verification of the security certificate on the authenticating server. Notes: • If using digital certificates to establish a secure connection to the authentication server, configure the certificates on the printer before changing 802.1X authentication settings. For more information, see "Managing certificates and other settings" on page 24. • Server certificate validation is integral to TLS (Transport Layer Security), PEAP (Protected Extensible Authentication Protocol), and TTLS (Tunneled Transport Security Layer).
