Securing Access to Wireless
Data
To prevent unauthorized stations from accessing data that is transmitted over
the network, the products support the following levels of security:
! “Restrict Wireless Access to the Network”
! Data encryption to encrypt all data transmitted via the wireless medium
(see Wireless Data Encryption).
These security measures that apply to communications at the “physical layer”
complement the “user name/password” validation at the “network layer” as
implemented by standard network operating systems.
Restrict Wireless Access to the
Network
To exclude unknown and unauthorized computing devices from establishing a
wireless connection to the network, you can use the following options:
! Closing your network to all stations that have not been programmed with
the correct network name (see Closing the Wireless Network).
! Use access control tables to build a list of authorized stations allowed to
establish a wireless connection with the network (see Access Control).
Closing the Wireless Network
Closing the wireless network prevents unauthorized users from accessing the
Base Station within a specified BreezeNET network. If a user tries to access the
network, without configuring their station with the correct network name, the
station will not be able to bridge data on the Base Station.
There are two options for this type of access security: Open and Closed.
! The Open configuration is the standard IEEE 802.11 mode that will allow
access to the Base Station for:
" all stations with the correct network name.
" all stations with the network name set to “ANY”.
! The Closed configuration is the BreezeNET proprietary mode that closes
your network to all stations that have not been programmed with the
correct network name.
This option will deny access to:
" all wireless stations with the network name set to “ANY” and,
