Understanding Security Features for Cisco Unified IP
Phones
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 Unified 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 Phones Series 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, refer to Cisco Unified Communications
Manager Security Guide.
If you configure security-related settings in Cisco Unified Communications
Manager Administration, the phone configuration file will contain sensitive
information. To ensure the privacy of a configuration file, you must configure it
for encryption. For detailed information, refer to the “Configuring Encrypted
Phone Configuration Files” chapter in Cisco Unified Communications Manager
Security Guide.
Table 1-2 shows where you can find additional information about security in this
and other documents.
