Wireless Security |
| |
Access Points nationwide are not locked down by a large percentage.
Even the ones that are maybe using an out-of-box configuration that is easy
to crack with the right tools and enough time.
We start by using the standard Windows XP SP2 Wireless configuration screens
as a reference to configure a wireless card. You may use a Vendor-supplied
wireless management utility for your card instead.

First Step: Right-Click Properties on your Wireless Card.
Select a Network in range (WPASite), and click Properties.
|
| |
Open/Disabled Associations have no security at all.
|
| |
For a WEP connection, first select Shared Authentication
(In WEP, two sides share a common key)
|
| |
Then select WEP encryption and input the Access Point's WEP Key
|
| |
WPA connections use 'WPA Authentication' and 'TKIP' encryption.
(WPA keys are stronger then WEP keys and the keys automatically change
over time via the Temporal Key Integrity Protocol')
|

You may have noticed that there are two WPA choices here.
The first (WPA/TKIP) allows for key exchange and authorization
schemes other than TKIP itself. You can select an EAP type
such as RADIUS or certificates from a PKI.
(WPA-PSK/TKIP) allows for a fixed key exchange sequence.
This is the typical selection for Access-Point only connections.
The key still changes like WPA/TKIP, but there is no large-scale
user-level access controls like an EAP provides.
