Chapter 1 An Overview of the Cisco Unified IP Phone
Understanding Security Features for Cisco Unified IP Phones
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 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.
