4.2.1 About ESSID Security Settings
Use the Encryption section of the WLAN > ESSID Definition > ESSID Settings screen to
configure the wireless security settings of the specified ESSID. The screen varies according to
the security modes you select.
The following table describes the security modes you can configure.
4.2.1.1 User Authentication
You can make every user log in to the wireless network before they can use it. This is called
“user authentication.” For wireless networks, there are typically two places to store the user
names and passwords for each person:
• In the AP or WLAN controller: this feature is called a local user database or a local
database.
• In a RADIUS server: this is a server used in businesses more than in homes.
If your AP or WLAN controller (in this case it is the NXC-8160) does not provide a local user
database and if you do not have a RADIUS server, you cannot set up user names and
passwords for your users.
Unauthorized 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.
