Identifying Unauthorized Aps - Alvarion BreezeACCESS Wi2 System Manual

Chapter 6 - Wireless Configuration
Operating mode is set to Monitor and, on this Wireless neighborhood page,
Repeat scan every is enabled.
Channel is set to Automatic.
Automatic power control is enabled.
The scanning interval is set based on the automatic power control and channel selection intervals
that are defined.
In the case of Monitor mode, scanning is continuous, switching channels each 200 ms. If none of
these options is defined, you must set the scanning interval manually.
Scanning is temporarily disabled when a Network trace is active.
Each time a scan is repeated, it moves up one channel in the range supported by the current wireless
mode (a/b/g). To view a list of all APs operating on all channels, you must perform multiple scans.
Define Repeat scan every accordingly. The results of each scan are shown in the All APs list.
When operating in Monitor mode, the AP scans all channels and all wireless modes (a/b/g).
Scanning is automatically performed on all active radios.
To identify unauthorized APs, the AP compares the MAC address of each discovered AP against the
list of authorized APs—which you must define. If the discovered AP does not appear in the list, it is
shown in the Unauthorized APs list.
6.2.2

Identifying Unauthorized APs

Improperly configured wireless APs can seriously compromise the security of a corporate network.
It is therefore important that these APs be identified as quickly as possible.
You can configure the wireless neighborhood feature to automatically list all unauthorized APs that
are operating nearby.
To identify unauthorized APs, the network neighborhood feature compares the MAC address of
each discovered AP against the list of authorized APs that you have defined as discussed below. If
the discovered AP does not appear in the list, its name is shown in the Unauthorized access points
list.
The list of authorized APs file is in XML format. Each entry in the file comprises two items: MAC
address and SSID. Each entry should appear on a new line. The easiest way to create this file is to
wait for a scan to complete, then open the list of all APs in Brief format. Edit this list so that it
contains only authorized AP and save it. Then specify the address of this file under List of
authorized access points.
