Understanding Security Profiles

All Cisco Cius devices that support Cisco Unified Communications Manager use a security profile, which

defines whether the device is nonsecure, authenticated, or encrypted. For information about configuring the

security profile and applying the profile to the device, see the Cisco Unified Communications Manager Security

Guide.

To view the security mode that is set for Cisco Cius, view the Signaling security mode setting in the Enterprise

security settings menu.

Identifying Secure (Encrypted) Phone Calls

Security is implemented for Cisco Cius by enabling the "Protected Device" parameter from the Cisco Unified

Communications Manager Administration Phone window. When security is implemented, you can identify

secure phone calls by the Secure Call icon on the Cisco Cius screen. In a secure call, all call signaling and

media streams are encrypted. A secure call offers a high level of security, providing integrity and privacy to

the call. When a call in progress is being encrypted, the Security Mode status on Cisco Cius Enterprise security

settings menu indicates "Encrypted."

If the call is routed through non-IP call legs (for example, PSTN), the call may be nonsecure even though

Note

it is encrypted within the IP network and has a lock icon associated with it.

In a secure call, a 2-second tone plays to notify the users when a call is encrypted and both devices are

configured as protected devices, and if secure tone features are enabled on Cisco Unified Communications

Manager. The tone plays for both parties when the call is answered. The tone does not play unless both devices

are protected and the call occurs over encrypted media. If the system determines that the call is not encrypted,

Cisco Cius plays a nonsecure indication tone (6 beeps) to alert the user that the call is not protected. For a

detailed description of the secure indication tone feature and the configuration requirements, see the Cisco

Unified Communications Manager Security Guide.

Video is transmitted as nonsecure. So, even if both Cisco Cius devices are secure, the Encrypted lock

Note

icon will not be displayed for video calls.
