is easily broken by an attacker (X) running readily available encryption-cracking

including sensitive data stored on the file server (C).

15.3 What You Need To Know

You can configure the NWA to detect rogue IEEE 802.11a (5 GHz) and IEEE

You can also set the NWA to e-mail you immediately when a rogue AP is detected
(see Chapter 19 on page 229
You can set how often you want the NWA to scan for rogue APs in the Rogue AP

Friendly APs
If you have more than one AP in your wireless network, you must also configure
the list of "friendly" APs. Friendly APs are other wireless access points, aside from
the NWA, that are detected in your network, as well as any others that you know
are not a threat (those from neighboring networks, for example). It is
recommended that you export (save) your list of friendly APs often, especially if
you have a network with a large number of access points. If you do not add them
to the friendly AP list, these access points will appear in the Rogue AP list each
time the NWA scans.
The friendly AP list displays details of all the access points in your area that you
know are not a threat. If you have more than one AP in your network, you need to
configure this list to include your other APs. If your wireless network overlaps with
