Recommended RAPIDS Rules
l
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
AirWave. 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.
l
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.
l
If More Than Four APs Have Discovered a Device, then Classify as Rogue
By default, AirWave 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. For additional
rules that may help you in your specific network scenario, contact Dell support at dell.com/support.
