Configuring with Web Based Management
6.10 "Security" menu
Description
The table has the following columns:
● Port
Shows the available ports.
● Authentication Type
Select the type of authentication. The selection depends on the operating mode and the
transmission standard.
Note
WLAN mode IEEE 802.11 n/ac
In WLAN mode IEEE 802.11n/ac, only WPA2 (WPA2-PSK and WPA2 RADIUS) encryption
is possible.
– Open System
– Shared Key
– WPA (RADIUS)
– WPA-PSK
– WPA2 (RADIUS)
– WPA2-PSK

There is no authentication. Encryption with a fixed (unchanging) WEP key can be
selected as an option. To use the key, enable "Encryption". You define the WEP key on
the "Keys" page.
In Shared Key authentication, a fixed key is stored on the client and access point. This
WEP key is then used for authentication and encryption. You define the WEP key on the
"Keys" page.
Note
If you use "Open System" with "Encryption" or "Shared Key", Key 1 must always be set
on the "Keys" page.
Wi-Fi Protected Access (WPA) is a method specified by the Wi-Fi Alliance to close
security gaps in WEP. Authentication using a server (802.1x) is mandatory. The dynamic
exchange of keys at each data frame introduces further security.
WPA Pre Shared Key (WPA-PSK) is a weakened form of WPA. In this method,
authentication is not carried out by a server but is based on a password. This password
is configured manually on the client and server.
WPA2 (Wi-Fi Protected Access 2) is a further development of WPA and implements the
functions of the IEEE 802.11i security standard. However, WPA authentication works
with the RADIUS server.
WPA2-PSK is based on the 802.11i standard. However, WPA authentication works
without a RADIUS server. Instead of this, a WPA(2) key (WPA(2) pass phrase) is stored
on each client and access point. The WPA(2) pass phrase is used for authentication and
further encryption.
