New York – Utility safety: Waterfall Security Solutions (Waterfall), which specializes in critical infrastructure and industrial control systems security, announced the launch of two new technologies: the Waterfall FLIP and the Waterfall Modular architecture. The technologies, in addition to the recently announced Waterfall for Bulk Electric System (BES) Control Centers solution, represent an expanded mission for the company to replace control system firewalls with stronger alternatives.
The solutions highlight the diverse ways that Unidirectional Security Gateway technology can meet the needs of control system administrators of power grids, oil and gas plants, water systems and pharmaceutical manufacturers. All three Waterfall products enable secure IT/OT integration and ensure the safety and reliability of critical control system networks, dramatically reducing the risk of a cyber attack occurring on critical infrastructure.
Waterfall’s core technology is the Unidirectional Security Gateway that replicates servers reliably and in real time via hardware-enforced unidirectional communications. Waterfall FLIP is a Unidirectional Security Gateway that temporarily reverses gateway orientation under the control of the protected network to allow occasional external inputs, such as production plans and equipment control schedules. Additionally, the Waterfall FLIP for Substations applies the FLIP technology to secure DNP3 protocol communications for high-voltage transmission substations. The new modular architecture reduces rack-spaces requirements for Unidirectional Security Gateway and FLIP solutions, and provides for end-user replacement and expansion of gateway equipment, without compromising security or enabling covert channels.
“Replacing control system firewalls with stronger technology that leverages Unidirectional Security Gateways will put critical infrastructures in a better position to face today’s threat environment,” said Andrew Ginter, Waterfall’s vice president of industrial security. “Waterfall’s new, expanded mission is to populate the spectrum of stronger-than-firewalls technologies and solutions.”
Rounding out the trifecta of stronger-than-firewall technology is the Waterfall for BES Control Centers solution, which leverages hardware-enforced Unidirectional Security Gateways to replicate inter-control-center protocol (ICCP) servers in two directions, deployed as two completely independent communications channels. Since the gateways replicate ICCP servers instead of forwarding packets as firewalls do, the gateways do not suffer from the many, well-known vulnerabilities that plague firewalls.
