Waterfall Founder Interviewed – Protection for Critical Infrastructure and SCADA

ROSH HA'AYIN, Israel, July 22, 2011 /PRNewswire/ --

Dr. Stephen Bryen, CEO and President at SDB-Partners LLC. and renowned
security commentator has posted an interview with Lior Frenkel, the CEO and
co-founder of Waterfall Security Solutions on his Technology and Security
blog. The interview explores the topic of Waterfall's Unidirectional
Security Gateway technology, and can be found at:

The gateways are a pair of network appliances and associated software.
The TX gateway sits in the protected control system network, and contains a
laser. The RX gateway sits in the external network, and contains a
photocell. As a result, the system can send information out of the protected
network, but nothing can get back in. No hackers, no viruses, no denial of
service attacks -- nothing at all can get back into the protected network.
The communications channel back into the network does not exist in the

The concept seems simple, but Dr. Bryen explores the technology with Mr.
Frenkel and digs into the details. For example - how can this possibly work?
Are not the vast majority of industrial protocols bi-directional? How can
you emulate a bi-directional protocol over a unidirectional medium? It turns
out the trick is to replicate servers rather than emulate protocols, a topic
the two explore in ways a non-technical audience can appreciate.

Cybersecurity for SCADA/control systems and critical infrastructure have
been widely criticized as inadequate in recent years. Control system
networks were once protected to some extent by isolation and by the use of
non-standard hardware and software computing platforms. However, the last 15
years have seen widespread use of commodity computing and operating system
platforms in industrial control systems. Furthermore, connections between
control systems and conventional corporate networks are now commonplace,
introducing the risk of attacks on control system networks either directly
from corporate networks, or indirectly from the Internet through corporate
networks. The Waterfall Gateways are a refreshing change to the SCADA
security landscape, as they provide absolute protection to control system
networks from all attacks from external networks, including denial of
service attacks, corporate insider attacks, botnets, and attacks from new
advanced persistent threats.
