DETECTING AND COMBATTING

ROGUE DEVICES

This chapter discusses how to manage rogue devices that try to use your

wireless network. Information includes an overview of detection features,

enabling countermeasures, using the Rogue Detection tab, displaying a

rogue’s geographical location, ignoring friendly third-party devices, and

converting a rogue into a third party AP.

Overview MAP radios automatically scan the RF spectrum for other devices

transmitting in the same spectrum. The RF scans discover third-party

transmitters in addition to other 3Com radios. MSS considers the

third-party transmitters to be devices of interest, which are potential

rogues.

You can display information about the devices of interest. To identify

friendly devices, such as third-party access points in your network or

neighbor’s network, you can add them to the known devices list. You

also can enable countermeasures to prevent clients from using the

devices that truly are rogues. With 3WXM, you also can display the

physical location of a rogue device.

RF detection detects all the IEEE 802.11 devices in a Mobility Domain and

can single out the unauthorized rogue access points.

Rogue Access Points

and Users

A rogue access point is an access point that is not authorized to operate

in a network. Rogue access points and their clients undermine the

security of an enterprise network by potentially allowing unchallenged

access to the network by any wireless user or client in the physical vicinity.

Rogue access points and users can also interfere with the operation of

your enterprise network.
