EL Device ZyXEL NWA 1100 User s Guide Chapter 7 Wireless Security Screen 7 3 What You Need To Know About Wireless Security 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 ina 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 The following table shows the relative effectiveness of wireless security methods Table 15 Wireless Security Levels SECURITY LEVEL SECURITY TYPE Least Unique SSID Default Secure Unique SSID with Hide SSID Enabled MAC Address Filtering WEP Encryption IEEE802 1x EAP with RADIUS Server Authentication Wi Fi Protected Access WPA Most Secure WPA2 The available security modes in your ZyXEL Device are as follows
