Securing printers 55 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 42. • Server certificate validation is integral to TLS (Transport Layer Security), PEAP (Protected Extensible Authentication Protocol), and TTLS (Tunneled Transport Security Layer). d Select Enable Event Logging to log activities related to 802.1X authentication. Warning-Potential Damage: To reduce flash part wear, use this feature only when necessary. e From the 802.1x Device Certificate list, select the digital certificate that you want to use. If only one certificate is installed, then default is the only option that appears. 3 Under Allowable Authentication Mechanisms, select the authentication protocols that the printer recognizes by clicking the check box next to each applicable protocol. 4 From the TTLS Authentication Method list, select the authentication method to accept through the secure tunnel created between the authentication server and the printer. 5 Apply the changes. Note: The print server resets when changes are made to settings marked with an asterisk (*) on the Embedded Web Server. Configuring IP security settings Apply IPSec between the device and the workstation or server to secure traffic between the systems with a strong encryption. The devices support IPSec with preshared keys and certificates. Both modes can be used simultaneously. In preshared key mode, devices are configured to establish a secure IPSec connection with up to five other systems. Devices and the systems are configured with a pass phrase that is used to authenticate the systems and to encrypt the data. In certificate mode, devices are configured to establish a secure IPSec connection with up to five systems or subnets. Devices exchange data securely with a large number of systems, and the process is integrated with a PKI or CA infrastructure. Certificates provide a robust and scalable solution, without configuring or managing keys and pass phrases. 1 From the Embedded Web Server, click Settings > Network/Ports > IPSec. 2 Configure the settings. • IPSec Enable-Enable or disable the IP security settings of your printer. • Connections-Configure the authenticated connections of your printer. • Settings-Specify the encryption and authentication methods of your printer. 3 Click Submit.
