Understanding Security Features for Cisco Unified IP Phones

Table 1-3	Overview of Security Features (continued)

Feature		Description

Media encryption		Uses SRTP to ensure that the media streams between supported devices proves secure and
		that only the intended device receives and reads the data. Includes creating a media master
		key pair for the devices, delivering the keys to the devices, and securing the delivery of the
		keys while the keys are in transport.

Signaling Encryption		Ensures that all SCCP signaling messages that are sent between the device and the Cisco
		Unified Communications Manager server are encrypted.

CAPF (Certificate Authority		Implements parts of the certificate generation procedure that are too processing-intensive
Proxy Function)		for the phone, and it interacts with the phone for key generation and certificate installation.
		The CAPF can be configured to request certificates from customer-specified certificate
		authorities on behalf of the phone, or it can be configured to generate certificates locally.

Security profiles		Defines whether the phone is nonsecure, authenticated, or
		encrypted.

Optional disabling of the web		You can prevent access to a phone’s web page, which displays a variety of operational
server functionality for a phone		statistics for the phone.

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 Network Configuration menu.
		For more information, see the “Displaying the Network Configuration Menu”
		section on page 4-1.

Understanding Security Profiles

All Cisco Unified IP Phones that support Cisco Unified Communications Manager 7.0 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, refer to Cisco Unified Communications Manager Security Guide, Release 7.0.

To view the security mode that is set for the phone, look at the Security Mode setting in the Security Configuration menu. For more information, see the “Network Configuration Menu” section on page 4-4.
