8.1
Security for the Wireless LAN
Reflecting on Wireless LANs often entails substantial doubts concerning secu-
rity. Many people suppose that abuse of data transmitted via radio links is rel-
atively simple.
Wireless LAN devices by LANCOM permit the employment of modern security
technologies:
Closed network
Access Control (via MAC-addresses)
LANCOM Enhanced Passphrase Security
Encryption of data transfer (802.11i/WPA or WEP)
802.1x / EAP
optional IPSec over WLAN (VPN), in combination with external VPN gate-
way
8.1.1
Closed network
Each Wireless LAN according to IEEE 802.11 has its own network name (SSID).
This network name serves as identification and enables administration of
Wireless LANs.
A Wireless LAN can be established in such a way that any user gets access to
this network. Such networks are called open networks. Any user can access
an open network also without knowledge of the WLAN network name
reserved specifically for this network. Only requirement is the input of the net-
work name 'ANY'.
In a closed network the access via 'ANY' is not possible. User have to specify
the correct network name. Unknown networks stay hidden to them.
Ad-hoc-networks are automatically installed as closed networks and cannot
be opened. Infrastructure networks can be run either in open or closed con-
dition. You make the settings for this at the respective base station.
