The oil and gas industry is responsible for providing over two-thirds of the energy requirements of the USA. With over 150 refineries, 200,000 miles of oil pipelines and 2 million gas pipelines, the industry is built on a highly decentralized infrastructural network. The importance and structure of the Oil and Gas industry is pretty much the same in other parts of the world. SCADA and DCS systems control these networks and in order to provide an uninterrupted supply of energy, these previously-isolated networks are now interconnected with business networks and subsequently the public internet. This interconnectedness has raised the security bar as the cyber vulnerabilities of the IT world have now been introduced into the SCADA infrastructure, threatening the resilience of these sensitive control and data acquisition networks. These cyber security vulnerabilities leave oil and gas companies susceptible to exploitation, attack and loss of proprietary information. Cyber attacks can be perpetrated both by outsiders as well as insiders and may be caused by design faults, employee errors, firewall misconfigurations, tardy software updates and circumvention of existing security elements such as IDS and IPS systems. Such attacks can have far –reaching and detrimental effects on oil and gas process control systems and could lead to the destabilization of the supply capabilities of this energy sector and have a cascading effect on the national economy itself.To effectively meet regulatory compliance and to ensure uninterrupted service, companies must address their overall security posture with adequate security measures.Waterfall Security Solutions provides a cutting-edge solution based on unique unidirectional technology. This solution enables secure and impenetrable information replication from critical SCADA networks to less-secure connected networks. Critical network are completely secured from online attacks and unauthorized access while remote monitoring is enabled.Waterfall Security Solutions Ltd. is the leading provider of Unidirectional Security Gateways for Process Control Systems, SCADA systems, Remote Monitoring and Segregated Networks. Waterfall’s products have been deployed in many homeland security agencies, critical national infrastructures and mission critical organizations in the USA, Canada, and Europe, as the central component of a strong regulatory compliance plan. Waterfall’s offerings include security solutions for leading industrial applications (such as the OSIsoft PI® Historian, Instep EDNA, GE Proficy Historian, the Siemens WinTS and the GE OSM remote monitoring platforms) and leading industrial protocols (such as OPC, Modbus, DNP3 and ICCP).Many of Waterfall Unidirectional Security Gateways™ installations are designed and aimed to assist in achieving compliance to NERC CIP, NRC and other regulations and requirements.
