Configuring Security for the Phone
Implementing security in the wireless network (WLAN) protects against data
tampering threats and identity theft of phones. To alleviate these threats, the Cisco
wireless LAN provides many 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 7921G, see the “Authentication Mechanisms in the Wireless Network”
section on page 2-19.
