Table 1-3 Overview of Security Features Feature Image authentication 802.1X Authentication Description Signed binary files (with the extension .sbn) prevent tampering with the firmware image before it is loaded on a phone. Tampering with the image causes a phone to fail the authentication process and reject the new image. The Cisco Unified IP Phone can use 802.1X authentication to request and gain access to the network. See the "Supporting 802.1X Authentication on Cisco Unified IP Phones" section on page 1-23 for more information.
