WPA2
WPA2 is the enhancement of WPA. In WPA2, the 802.11i standard is not only implemen-
ted for the first time in full, but another encryption algorithm AES (Advanced Encryption
Standard) is also used.
Access control
You can control which clients can access your wireless LAN via your device by creating an
Access control list (ACL Mode or MAC Filter). In the Access Control List, you enter the
MAC addresses of the clients that may access your wireless LAN. All other clients have no
access.
Security measures
To protect the data transferred on the WLAN, you may need to carry out the following con-
figuration steps in the Wireless LAN->WLANx->Virtual Service Sets->New->/ menu:
• Change the access passwords for your device.
• Change the default SSID, Network Name (SSID) = Funkwerk-ec , of your access
point. Set Visible = Enabled. This will exclude all WLAN clients that attempt to establish
a connection with the general value for Network Name (SSID) Any and do not know the
SSID settings.
• Use the available encryption methods. To do this, select Security Mode = WEP 40, WEP
104 , WPA PSK or WPA Enterprise or both, and enter the relevant key in the access
point under WEP Key1 - 4 or Preshared Key and in the WLAN clients.
• The WEP key should be changed regularly. To do this, change the Data Transfer Key .
Select the longer 104 Bit WEP key.
• For the transfer of highly security-critical information, Security Mode = WPA-
Enterprise should be configured with WPA Mode = WPA 2. This method contains
hardware-based encryption and RADIUS authentication of the client. In special cases,
combination with IPSec is possible.
• Restrict WLAN access to permitted clients. Enter the MAC addresses of the wireless net-
work cards of these clients in the Permitted Addresses -list in the MAC Filter menu (see
Fields in the menu MAC Filter on page 160).
In the Wireless LAN -> WLANx -> Wireless Networks (VSS) menu, a list of all WLAN
networks shown.
