Deleting or Editing a Rules
To delete a rule from the RAPIDS rules list, go to the RAPIDS > Rules page. Select the check box next to the
rule you want to delete, and click the Delete button. The rule is automatically deleted from the RAPIDS > Rules

Recommended RAPIDS Rules

If Any Device Has Your SSID, Then Classify as Rogue
The only devices broadcasting your corporate SSID should be devices that you are aware of and are managed
by AWMS. Rogue devices often broadcast your official SSID in an attempt to get access to your users, or to
trick your users into providing their authentication credentials. Devices with your SSID generally pose a severe
threat. This rule helps to discover, flag, and emphasize such a device for prompt response on your part.

If Any Device Has Your SSID and is Not an Ad-Hoc Network Type, Then Classify as Rogue
This rule classifies a device as a rogue when the SSID for a given device is your SSID and is not an Ad-Hoc
device. Windows XP automatically tries to create an Ad-hoc network if it can not find the SSID for which it is
searching. This means that user’s laptops on your network may appear as Ad-Hoc devices that are
broadcasting your SSID. If this happens too frequently, you can restrict the rule to apply to non-ad-hoc
devices.

If More Than Four APs Have Discovered a Device, Then Classify as Rogue
By default, AWMS tries to use Signal Strength to determine if a device is on your premises. Hearing device
count is another metric that can be used.
The important concept in this scenario is that legitimate neighboring devices are only heard by a few APs on
the edge of your network. Devices that are heard by a large number of your APs are likely to be in the heart of
your campus. This rule works best for scenarios in large campuses or that occupy an entire building.
Using RAPIDS Rules with Additional AWMS Functions
Rules that you configure on the RAPIDS > Rules page establish an important way of processing rogue devices on
your network, and flagging them for attention as required. Such devices appear on the following pages in AWMS,
with additional information:

RAPIDS > List —Lists rogue devices as classified by rules.

RAPIDS > Rules —Displays the rules that classify rogue devices.

RAPIDS > Overview —Displays general rogue device count and statistical information.

System > Triggers —Displays triggers that are currently configured, including any triggers that have been
defined for rogue events.

Reports > Definitions —Allows you to run New Rogue Devices Report with custom settings.

VisualRF —Displays physical location information for rogue devices.
Score Override
On RAPIDS > Score Override page you can change the OUI scores that are given to MAC addresses detected
during scans of bridge forwarding tables on routers or switches. Figure 137 , Figure 138 , and Table 109 illustrate
and describe RAPIDS Score Override. Perform these steps to create a score override.
