RF Activity Detected With Sensor Solution

Bastille Networks has released a portable kit for temporary deployments to help government agencies and companies view and manage the wireless activity taking place in their secure areas.

RF transmissions are proliferating in commercial and government enterprises, from the devices people carry with them to facilities' Internet of Things (IoT) appliances. These items transmit over frequencies ranging from Bluetooth to cellular and from beacons to RFID. That heavy wireless traffic poses a security concern for many businesses. In some cases, an organization may need to eliminate those transmissions entirely, while others might simply want to understand what communication is taking place and be alerted if a vulnerability is created.

Bastille Networks has developed a solution that is being employed by the U.S. Department of Homeland Security (DHS), other Department of Defense (DoD) agencies and financial institutions. Its solutions detect all transmissions between 60 MHz and 6 GHz, then reports that wireless traffic to a central server. Recently, Bastille Networks released a portable kit known as Bastille Express, providing a temporary solution that the company says is easy to install and take down.

The firm already provides the system to the DoD under the name Bastille Flyaway Kit. The kit consists of five Bastille RF sensor devices and a laptop in a pelican case, enabling users to set up an RF security system within a temporary space. In the meantime, the DHS has completed the fourth phase of a system using Bastille's technology to detect the presence of any RF transmissions in public or within secure areas.

Bastille's solution consists of an array of sensors, developed and manufactured in the United States, that monitor for wireless emitters, then not only identify what transmission is taking place, but also provide the location of each transmitting device within about 3 meters (9.8 feet) of accuracy on a floor plan map of a user's facility. The system can issue alerts to notify management of any transmission that falls outside of the authorized or expected protocol.

Throughout the past few years, Bastille has worked with the DHS to develop technology which could be used to protect the nation and secure enterprises. In some cases, for instance, government agencies may require an environment completely devoid of RF or cellular transmissions. That poses an increasingly challenging requirement, however, according to Bob Baxley, Bastille's chief technology officer. More than 70 percent of devices currently connected to the network are connected via RF and cellular transmission, he explains. Some may be connected to a facility's existing network, while others may not, and that creates security concerns.
