Appliance helps bust Wi-Fi thieves

Wi-Fi moochers beware

Wi-Fimoochers beware: eTelemetry has released a new device that's designed to spoil your free ride.

ETelemetry, a company that specializes in extracting information from enterprise network traffic, last week released an update to its Locate network appliance, that will give companies the ability to sniff out and disable rogue wireless access points that are connecting to their network.

The problem, says eTelemetry CTO Alan Schunemann, is a common one: employees bring in their own private mini hub or switch and hooking it up to the network as a rogue access point. The Locate feature, he says, helps solve this problem by using eTelemetry's "IP-to-people" technology that maps users by monitoring all traffic for logon information to services such as instant messaging, e-mail and Active Directory. Thus, the technology is able to correlate people on the network to IP addresses, media access control addresses and switch ports in real time.

The new Locate 4.1 update uses this IP-to-people data to determine when a new or unknown user, device and IP address appears on the corporate network, including rogue devices that are using unauthorized Wi-Fi. From there, Locate sends out a security alert letting the IT department know that an unauthorized access point is connecting to the network . Locate also gives the department the ability to directly shut down all rogue access points that it identifies on the network, Schunemann says.

"What's nice about our product is that once you know where the rogue access point is, you can identify the person who probably set it up," says eTelemetry CEO Ermis Sfakiyanudis. "It's a rack-mountable 1U device that you can peg to the network through a normal switchboard connection."

Prices for eTelemetry's Locate 4.1 start at US$7,500 for the hardware and 500 client licenses. Users can purchase packages of 500 additional licenses for US$1,000 each.

For work use, Microsoft Word and Excel programs pre-installed on the device are adequate for preparing short documents.

LIFEBOOK UH574

The Fujitsu LifeBook UH574 allowed for great mobility without being obnoxiously heavy or clunky. Its twelve hours of battery life did not disappoint.

STYLISTIC Q702

The screen was particularly good. It is bright and visible from most angles, however heat is an issue, particularly around the Windows button on the front, and on the back where the battery housing is located.

STYLISTIC Q702

My first impression after unboxing the Q702 is that it is a nice looking unit. Styling is somewhat minimalist but very effective. The tablet part, once detached, has a nice weight, and no buttons or switches are located in awkward or intrusive positions.
