To add another layer of security when your users connect to your wireless network, you can enable enterprise authentication methods on your XTM wireless device. When you configure an enterprise authentication method, the client must have the correct authentication method configured to successfully connect to the XTM device. The XTM wireless device then sends authentication requests to the configured authentication server (RADIUS server or Firebox-DB). If the authentication method information is not correct, the user cannot connect to the device, and is not allowed access to your network.
If your device runs Fireware XTM v11.0-v11.3.x, the authentication methods based on the IEEE 802.1X standard are not available.
In Fireware XTM v11.4 and later, the available enterprise authentication methods are WPA Enterprise and WPA2 Enterprise. These authentication methods are based on the IEEE 802.1X standard, which uses the EAP (Extensible Authentication Protocol) framework to enable user authentication to an external RADIUS server or to your XTM device (Firebox-DB). The WPA Enterprise and WPA2 Enterprise authentication methods are more secure than WPA/WPA2 (PSK) because users must first have the correct authentication method configured, and then authenticate with their own enterprise credentials instead of one shared key that is known by everyone who uses the wireless access point.
You can use the WPA Enterprise and WPA2 Enterprise authentication methods with XTM wireless devices. For more information about how to configure your XTM wireless device to use enterprise authentication, see Set the Wireless Authentication Method.
