7.1.4 Encryption of the data transfer
A special role comes up to the encryption of data transfer for Wireless LANs.
For IEEE 802.11 radio transfer the supplementing encryption standards are
802.11i/WPA and WEP. The function of the encryption is to ensure the security
level of cable-bound LANs also in Wireless LANs.
࡯
Use encryption on the data transferred in the WLAN. Activate the strong-
est possible encryption available to you ((802.11i with AES, WPA or WEP)
and enter the appropriate keys or passphrases into the access point and
the WLAN clients.
࡯ Regularly change the WEP keys in your access points. The passphrases for
802.11i or WPA do not have to be changed regularly as new keys are gen-
erated for each connection anyway. This is not the only reason that the
encryption with 802.11i/AES or WPA/TKIP is so much more secure than
the now aged WEP method.
࡯
If the data is of a high security nature, you can further improve the encryp-
tion by additionally authenticating the client with the 802.1x method or
activate an additional encryption of the WLAN connection as used for VPN
tunnels ('IPSec over WLAN'). In special cases, a combination of these two
mechanisms is possible.
 Further details to WLAN security and the used encoding methods can
be found in the LCOS reference manual.

tion“.
