Understanding Security Profiles
All Cisco Unified IP Phones that support Cisco Unified Communications Manager use a security profile,
which defines whether the phone is nonsecure, authenticated, or encrypted. For information about
configuring the security profile and applying the profile to the phone, see Cisco Unified Communications
Manager Security Guide.
To view the phone security mode, look at the Security Mode setting in the Security Configuration menu.
For more information, see
Security Configuration Menu, page 4-32.

Identifying Authenticated, Encrypted, and Protected Phone Calls
When security is implemented for a phone, you can identify authenticated or encrypted phone calls by
icons on the screen on the phone. You can also determine if the connected phone is secure and protected
if a security tone plays at the beginning of the call.
Phone hardening Additional security options, which you control from Cisco Unified Communications Manager
Administration:
• Disabling PC port
• Disabling Gratuitous ARP (GARP)
• Disabling PC Voice VLAN access
• Disabling access to the Setting menus, or providing restricted access that allows access to
the User Preferences menu and saving volume changes only
• Disabling access to web pages for a phone
Note You can view current settings for the PC Port Disabled, GARP Enabled, and Voice
VLAN enabled options by looking at the phone’s Security Configuration menu. For
more information, see
Device Configuration Menu, page 4-18.
802.1X Authentication The Cisco Unified IP Phone can use 802.1X authentication to request and gain access to the
network. See
Supporting 802.1X Authentication on Cisco Unified IP Phones, page 1-19 for
more information.
