Chapter 25 Wireless LAN This type of security is fairly weak, however, because there are ways for unauthorized wireless devices to get the SSID. In addition, unauthorized wireless devices can still see the information that is sent in the wireless network. 25.5.3.2 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 they can use 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. 25.5.3.3 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 25.5.3.2 on page 200 for information about this.) Table 50 Types of Encryption for Each Type of Authentication NO AUTHENTICATION RADIUS SERVER Weakest No Security Static WEP WPA-PSK Strongest WPA2-PSK WPA 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 N4100 and you do not have a RADIUS server. Therefore, there is no 200 N4100 User's Guide

This type of security is fairly weak, however, because there are ways for
unauthorized wireless devices to get the SSID. In addition, unauthorized wireless
devices can still see the information that is sent in the wireless network.
25.5.3.2
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 they can use 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.
25.5.3.3
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 25.5.3.2 on page 200
for information about this.)
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 N4100 and you do not have a RADIUS server. Therefore, there is no
