Waterfall Security Granted Patent for Secure Implementation of Network-Based Sensors
TEL AVIV, Israel, September 6, 2012/PRNewswire/ --
The United States Patent Office has granted Waterfall Security Solutions Ltd., the
leading provider of Unidirectional Security Gateways(TM) for critical infrastructure
networks, patent 8,223,205 for "A Secure Implementation of Network-Based Sensors." The
patent describes how to feed data from network-based security sensors, such as video
cameras on control system networks, into security operations centers on less-secure
networks, without introducing any threat to the safety or reliability of the sensor
network itself.
"Network-based security sensors and especially video sensors are increasingly part of
sophisticated defense-in-depth cyber-security measures at industrial sites," reports
Andrew Ginter, Waterfall's Director of Industrial Security. "Couple this trend with the
trend towards centralized, cloud-based and out-sourced Security Operations Centers and you
have a problem. With conventional firewall-based security, every communications channel
out of a secure control-system network is also an attack channel back into that network.
Putting the safety and reliability of industrial networks at risk, just so you can monitor
those sites centrally, is not a good trade-off."
The patent describes how to send security sensor data, such as video data, out of
safety-critical and reliability-critical networks using Unidirectional Security Gateways.
The hardware-enforced gateways allow the data to reach central monitoring sites and
out-sourced monitoring sites without introducing any risk to the originating network. The
unidirectional hardware permits video data and other data to leave a protected network,
but allows no signal whatsoever back into the network.
Video feeds in particular are used increasingly in industrial networks. Remote,
un-staffed sites are often monitored via video, as are locations where members of the
public are part of the physical process, such as airports, subway stations, and vehicular
traffic monitoring. These video feeds may be monitored in a variety of locations - some
secure and some less so. Some video feeds may be made available routinely to members of
the public over the Internet for example. When video feeds are made available to viewers
in less-secure networks, it is important to protect the integrity of the original video
sensor, and of any other sensing or control equipment on the same network as the video
sensor. Hardware-enforced Unidirectional Security Gateways allow security sensor data to
be shared, without putting the originating sensors and networks at risk.
"Waterfall is pioneering unidirectional protection of industrial sites and networks,"
adds Lior Frenkel, CEO and Co-Founder of Waterfall Security Solutions. "Our development
teams are constantly adding to our suite of unidirectional security products, and our
patents speak for themselves."
