Guide.

Description

Signed binary files (with the extension .sbn) prevent tampering

with the firmware image before it is loaded on a Cisco Cius

device. Tampering with the image causes Cisco Cius to fail the

authentication process and reject the new image.

Each Cisco Cius requires a unique certificate for device

authentication. Cisco Cius devices 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

Certificate Authority Proxy Function (CAPF). Alternatively,

you can install a Locally Significant Certificate (LSC) from the

Enterprise security menu on the device. See the
