The Department of Homeland Security (DHS) has selected Waterfall Security Solutions‘ Unidirectional Security Gateways to be part of the department’s Control Systems Security Program (CSSP) cyber security testbed located and operated by the Idaho National Laboratory. The test bed is an environment where control and monitoring systems, including Supervisory Control and Data Acquisition systems, energy management systems, process control systems, distributed control systems, and third party security components are evaluated for cyber security vulnerabilities. The DHS CSSP program is tasked with reducing vulnerabilities in industrial control systems that support and manage U.S. critical infrastructure. Waterfall, which is based in Israel, says its products are deployed in utilities, critical infrastructures, and homeland security agencies and enable online transmission of data from one network to another in a unidirectional mode only so that no data can pass backwards.
