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