Validating wireless connection

posted by | Leave a comment

You can quickly setup a wireless network using the wireless configuration feature in Windows XP.

Each computer you want part of a wireless network will need a wireless network card installed.

Though most of the 802.1X authentication protocols are secure, they're still prone to some vulnerabilities.

PEAP, the most popular protocol, for instance is susceptible to man-in-the-middle attacks.

This validation helps clients verify that they are speaking to the correct RADIUS server during the authentication process and not a fake server as previously mentioned.

In Windows Vista and later, Server Validation should be automatically enabled by Windows.

Sometimes you cannot use the Windows functionality.

Today we'll discuss server validation for 802.1X clients.

Using 802.1X authentication for your network improves its security.

On the wireless side, it enables use of the Enterprise mode of Wi-Fi Protected Access (WPA) or WPA2.

This allows users to receive unique usernames and passwords to log in to the Wi-Fi network, thus enabling admins to better manage access to the Wi-Fi.

802.1X requires the use of an authentication server, which is usually referred to as a Remote Authentication Dial-In User Service (RADIUS) server.
