NIC Security

Network interface cards (NICs) work much more efficiently if you can
eliminate as much complexity as possible when dealing with both infrastructure
and ad hoc network modes. What you need to do is set the network
adapter configuration through an automated method, because the
biggest problem is when the wireless user starts setting these parameters
himself.

Configuration problems that need to be fixed usually deal with client
configuration, most especially when working with multiple operating systems. Whenever the client moves between one operating system and
another, you can be sure that you will have to reset an entire set of configuration
options for the user and even some of the network resources
that he accesses.

Most 802.11 NICs support default methods of authentication. The
default authentication algorithm first tries to use shared-key authentication
if the network adapter has been preset to use a WEP shared key.
However, if the level of authentication stops working because the NIC is
not set up with a WEP shared key, then the NIC will always go back to
its lowest common denominator, open system authentication. This opens
the floodgates for unauthorized users to roam right onto your network
virtually undetected.
