BlueSocket

One vendor of an effective hardware solution is Blue-
Socket, which has produced a wireless gateway that establishes a firewall
between the access point and the corporate intranet. This device
requires that authentication take place through either its internal database
or a central corporate server.
This device also supports “central” authentication (Figure 15.4)
through its support of:

Lightweight directory access protocol (LDAP)

RADIUS

Windows NT 4 domain

Windows 2000 active directory

Extensible authentication protocol (EAP)

Token-based authentication
You can also use specific roles to assign various encryption levels for
each user depending on his specific need for security. When you assign
roles, you can also support a level of maximum bandwidth for each user
category. In addition, you can support “strong encryption” to deal with
the weaknesses of WEP.
