Protecting Your Network

WAP4410N Wireless-N Access Point with Power Over Internet Administration Guide

-

Use “Shared Key” authentication.

-

Change your WEP key regularly.

•

WPA/WPA2 Personal—

The WPA-Personal and WPA2-Personal methods

offer two encryption methods, TKIP and AES, with dynamic encryption
keys.

•

WPA /WPA2 Enterprise—

The WPA-Enterprise and WPA2-Enterprise

option requires that your network has a RADIUS server for authentication.

A network encrypted with WPA/WPA2 is more secure than a network
encrypted with WEP, because WPA/WPA2 uses dynamic key encryption.
To protect the information as it passes over the airwaves, you should enable
the highest protection level.

Implementing encryption may have a negative impact on your network’s
performance, but if you are transmitting sensitive data over your network,
encryption should be used.

!

CAUTION

Remember that each device in your wireless network

must

use the same

encryption method and encryption key or your wireless network will not function
properly
