Description

Defines whether Cisco Cius is nonsecure, authenticated,

encrypted, or protected. For more information about these

features and about Cisco Unified Communications Manager

and Cisco Cius security, see the Cisco Unified Communications

Manager Security Guide.

Lets you ensure the privacy of Cisco Cius configuration files.

For security purposes, you can prevent access to a Cisco Cius

web page (which indicates a variety of operational statistics for

the device) and user options pages. For more information, see

the

Enabling and Disabling Web Page

Additional security options, which you control from Cisco

Unified Communications Manager Administration:

• Disabling PC port on the media station

• Disabling Gratuitous ARP (GARP)

• Disabling PC Voice VLAN access

• Providing restricted access to the web applications

• Disabling Bluetooth Accessory Port

• Disabling access to web pages

• Requiring a screen lock

• Controlling access to Google Android market.

• Controlling access to installation of applications from

unknown sources

Cisco Cius can use 802.1X authentication to request and gain

access to the network. See the

Authentication on Cisco Cius, on page 19

information.

After you configure an SRST reference for security and then

reset the dependent devices in Cisco Unified Communications

Manager Administration, the TFTP server adds the SRST

certificate to the Cisco Cius cnf.xml file and sends the file to

the device. A secure device then uses a TLS connection to

interact with the SRST-enabled router.

Ensures that all SIP signaling messages that are sent between

the device and the Cisco Unified CM server are encrypted.
