5.10.3.3 User Authentication
Authentication is the process of verifying whether a wireless device is allowed to use the wireless
network. You can make every user log in to the wireless network before using it. However, every
device in the wireless network has to support IEEE 802.1x to do this.
For wireless networks, you can store the user names and passwords for each user in a RADIUS
server. This is a server used in businesses more than in homes. If you do not have a RADIUS server,
you cannot set up user names and passwords for your users.
Unauthorized wireless devices can still see the information that is sent in the wireless network,
even if they cannot use the wireless network. Furthermore, there are ways for unauthorized
wireless users to get a valid user name and password. Then, they can use that user name and
password to use the wireless network.
5.10.3.4 Encryption
Wireless networks can use encryption to protect the information that is sent in the wireless
network. Encryption is like a secret code. If you do not know the secret code, you cannot
understand the message.
The types of encryption you can choose depend on the type of authentication. (See
Section
5.10.3.3 on page 66
for information about this.)
Table 20
Types of Encryption for Each Type of Authentication
No Authentication
RADIUS Server
Weakest
No Security
WPA
Static WEP
WPA-PSK
Strongest
WPA2-PSK
WPA2
For example, if the wireless network has a RADIUS server, you can choose
WPA
or
WPA2
. If users
do not log in to the wireless network, you can choose no encryption,
Static WEP
,
WPA-PSK
, or
WPA2-PSK
.
Usually, you should set up the strongest encryption that every device in the wireless network
supports. For example, suppose you have a wireless network with the Device and you do not have
a RADIUS server. Therefore, there is no authentication. Suppose the wireless network has two
devices. Device A only supports WEP, and device B supports WEP and WPA-PSK. Therefore, you
should set up
Static WEP
in the wireless network.
Note: It is recommended that wireless networks use
WPA-PSK
,
WPA
, or stronger
encryption. The other types of encryption are better than none at all, but it is still
possible for unauthorized wireless devices to figure out the original information
pretty quickly.
When you select
WPA2
or
WPA2-PSK
in your Device, you can also select an option (
WPA
compatible
) to support WPA as well. In this case, if some of the devices support WPA and some
support WPA2, you should set up
WPA2-PSK
or
WPA2
(depending on the type of wireless network
login) and select the
WPA compatible
option in the Device.
