802.1X Authentication for the Cisco Unified IP Phone
Supported Security Features
The following table provides an overview of the security features that the Cisco Unified IP Phone 7931G
supports. For more information about these features and about Cisco Unified Communications Manager and
Cisco Unified IP Phone security, see the Cisco Unified Communications Manager Security Guide.
For information about current security settings on a phone, look at the settings on the Security Configuration
menus on the phone. For more information, see Security Configuration Menu and Security Configuration
Menu.
Most security features are available only if a Certificate Trust List (CTL) is installed on the phone. For
more information about the CTL, see the Cisco Unified Communications Manager Security Guide,
“Configuring the Cisco CTL Client” chapter.
Note
Table 3: Overview of Security Features
DescriptionFeature
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.
Image authentication
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 Certificate Authority Proxy Function (CAPF). Alternatively, you can install an LSC
from the Security Configuration menu on the phone. For more information, see Cisco Unified
IP Phone Security.
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 using transport layer security
(TLS) protocol. Cisco Unified Communications Manager will not register phones unless they
can be authenticated by the Cisco Unified Communications Manager.
