Cisco Unified IP Phones Security Features
Cisco Unified IP Phones Security Features
Implementing security in the Cisco Unified Communications Manager system prevents identity theft of the
phone and Cisco Unified Communications Manager server, prevents data tampering, and prevents call signaling
and media stream tampering.
To alleviate these threats, the Cisco IP telephony network establishes and maintains authenticated and encrypted
communication streams between a phone and the server, digitally signs files before they are transferred to a
phone, and encrypts media streams and call signaling between Cisco Unified IP Phones.
The Cisco Unified IP Phone 6901 and 6911 use the Phone security profile, which defines whether the device
is nonsecure, authenticated, or encrypted. For information on applying the security profile to the phone, see
the Cisco Unified Communications Manager Security Guide.
If you configure security-related settings in Cisco Unified Communications Manager, the phone configuration
file contains sensitive information. To ensure the privacy of a configuration file, you must configure it for
encryption. For detailed information, see the "Configuring Encrypted Phone Configuration Files" chapter in
Cisco Unified Communications Manager Security Guide.
The following table shows where you can find additional information about security in this and other documents.
