Chapter 1 An Overview of the Cisco Unified IP Phone Understanding Security Features for Cisco Unified IP Phones Providing Users with Feature Information If you are a system administrator, you are likely the primary source of information for Cisco Unified IP Phone users in your network or company. To ensure that you distribute the most current feature and procedural information, familiarize yourself with Cisco Unified IP Phone documentation. Make sure to visit the Cisco Unified IP Phone web site: http://www.cisco.com/en/US/products/hw/phones/ps379/tsd_products_support_series_home.html From this site, you can access various user guides, including wallet cards. In addition to providing users with documentation, it is important to inform them about available Cisco Unified IP Phone features-including features specific to your company or network-and about how to access and customize those features, if appropriate. For a summary of some of the key information that phone users need their system administrators to provide, see Appendix A, "Providing Information to Users Via a Website." 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 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.
