Cisco Unified IP Phone and Cisco Unified Communications Manager Security Topics
provides an overview of the security features that the Cisco Unified IP Phone 7975G supports.
Description
Signed binary files (with the extension .sgn) 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.
Each Cisco Unified IP Phone requires a unique certificate for device
authentication. Phones include a manufacturing installed certificate
(MIC), but for additional security, you can specify in Cisco
Unified Communications Manager Administration that a certificate
be installed by using the CAPF
LSC from the Security Configuration menu on the phone. See the
"Configuring Security on the Cisco Unified IP Phone" section on
page 3-13 for more information.
