Meru Networks' RF Barrier Blocks Parking Lot Attacks
Filed in archive Wi-Fi by jeff goldman on July 28, 2008
Meru Networks today introduced RF Barrier, an 802.11-based solution for protecting wireless networks from access by so-called "parking lot attackers" who try to get onto a corporate network from outside the perimeter of the building.
"Meru
's RF Barrier product is quite sophisticated, employing directional antennas mounted outside the walls and a special wireless access point (WAP) along the inside perimeter of a building," explains The Inquirer's Tony Dennis. "The WAP inspects the traffic in real time to determine which data appertains to the WLAN being protected and is therefore designated as sensitive. It then tells the directional antenna to block that bit of the RF spectrum. RF Barrier technology then uses the external antenna to block outbound traffic at the RF layer. Would-be attackers are limited in their ability to see useful packet information about the internal network."
"Start-up Xirrus offers a similar capability with the Sharp Cell technology in its Wi-Fi radio arrays that helps enterprises sharply define the edge of a coverage area and limit RF bleed," notes Network World's Joanie Wexler.
The solution will be available starting in September, with a four-antenna starter kit priced at $3,595.
