3.7.1 WEP
WEP (Wired Equivalency Protocol) was the first scheme to provide security for IEEE 802.11 communications.
Although since its release it has been determined to contain serious weaknesses, WEP remains an effective means
to prevent casual eavesdropping.
WEP settings are made network-wide; all BreadCrumb devices and wireless clients must agree on a WEP key in
order to establish and maintain communications.
To enable WEP on a BCWN, make sure that all of the BreadCrumbs to configure are visible in BCAdmin. Then
choose Security, then WEP Settings to display the following window:
Figure 16. WEP Configuration Screen
3.7.1.1. WEP
This dropdown allows the administrator to enable or disable WEP on all BreadCrumb devices currently visible in
BCAdmin.
3.7.1.2. KEY
A 40-bit or 104-bit hexadecimal key is specified in this field. If this field is left blank, WEP can be enabled using
a previously configured key.
3.7.2 ACCESS CONTROL LISTS (ACLs)
ABCWN may be configured with a network-wide Access Control List (ACL) to specify a list of devices to allow
or disallow on the network. Each device communicating on the
network (e.g., each BreadCrumb radio or laptop
radio card) has a unique identifier known as a MAC address. ACLs consist of lists of these addresses to specify
permitted or forbidden devices.
When enabled, the ACL may be in two modes: Deny by Default and Allow by Default. In Deny by Default mode,
client devices and BreadCrumb devices are not permitted on the network unless they are listed in the ‘Permitted
Devices’ ACL. In Allow by Default mode, client devices and BreadCrumb devices are permitted on the network
unless they are listed in the ‘Forbidden Devices’ ACL.
To edit the ACLs, click the ACL button in the toolbar. A window resembling the following will appear:
