TotalWatch also now monitors the 4.9GHz frequency, which is set aside for dedicated public safety Wi-Fi applications.
A related technology more efficiently blocks the rogue devices once they've been detected. Traditionally, intrusion-prevention systems have sent out continuously de-authentication frames to the attacker, forcing it to disconnect from the access point. But this consumes a lot of both bandwidth and airtime, according to Aruba. The new version of ArubaOS now can create a fake access point to which the attacker connects.
But then the network simply doesn't respond to the requests being made by the attacker's Wi-Fi adapter. While the human behind the attacks intervenes to puzzle out what's wrong, the controller is alerting the IT department, and tracking down the attacker's location.
ArubaOS 6.0 will ship on all future controller models and is available now for free download by current customers from the Aruba Web site. Controller and access point pricing is unchanged.
Aruba is also releasing three documents, drawn from working with its enterprise customers, on Wi-Fi best practices in three areas: a reference design for creating high-density networks in spaces like auditoriums; a white paper on deploying Apple iPad tablets on enterprise Wi-Fi networks; and a third-party test report on the performance of Aruba's RF management features in high-density Wi-Fi networks.
