Security Features
Implementing security in a wireless network protects against data tampering to Cisco Unified Communications
Manager data, call signaling, and media stream. It also reduces the chances for identity theft. To reduce the
threats, the Cisco wireless LAN (WLAN) provides options for user authentication with servers and for
encrypting communications streams between phones and network devices.
For information about supported security options for the Cisco Unified Wireless IP Phone, see Authentication
Methods, on page 39.
For information about security features supported by Cisco Unified Communications Manager and Cisco
Unified Wireless IP Phones, see Supported Security Features, on page 15.
