Cisco 8832 Administration Guide

DescriptionFeature
Each 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 Certificate Authority Proxy Function
(CAPF). Alternatively, you can install a Locally
Significant Certificate (LSC) from the Security
Configuration menu on the phone.
Customer-site certificate installation
Occurs between the Cisco Unified Communications
Manager server and the phone when each entity
accepts the certificate of the other entity. Determines
whether a secure connection between the phone and
a Cisco Unified Communications Manager should
occur; and, if necessary, creates a secure signaling
path between the entities by using TLS protocol. Cisco
Unified Communications Manager will not register
phones unless they can be authenticated by the Cisco
Unified Communications Manager.
Device authentication
Validates digitally signed files that the phone
downloads. The phone validates the signature to make
sure that file tampering did not occur after the file
creation. Files that fail authentication are not written
to Flash memory on the phone. The phone rejects such
files without further processing.
File authentication
Uses the TLS protocol to validate that no tampering
has occurred to signaling packets during transmission.
Signaling Authentication
Each phone contains a unique manufacturing installed
certificate (MIC), which is used for device
authentication. The MIC is a permanent unique proof
of identity for the phone, and allows Cisco Unified
Communications Manager to authenticate the phone.
Manufacturing installed certificate
After you configure a SRST reference for security
and then reset the dependent devices in Cisco Unified
Communications Manager Administration, the TFTP
server adds the SRST certificate to the phone cnf.xml
file and sends the file to the phone. A secure phone
then uses a TLS connection to interact with the
SRST-enabled router.
