Billions of people depend every day on mass transit services and public transportation. The transport industry views the acquisition of “Business knowledge” paramount in its decision-making processes. Protecting that information and preserving the reliability of the stored data within its mission control systems enhances the company’s competitive edge. As IT networks converge with these control system infrastructures, ensuring the resilience of the control system infrastructure is non-negotiable. The interconnectedness of the DCS network and Business network exposes the mission control system to the cyber threats associated with the IT world.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 firewalls, IDS and IPS systems. Such attacks can have far –reaching and detrimental effects on the transportation and traffic, navigation and control systems and could lead to serious interruptions, disastrous results and complete chaos.To effectively ensure uninterrupted services, companies must address their overall security posture by cutting edge technology that will guarantee absolute security and yet enable efficient connectivity.Waterfall Security Solutions provides a cutting-edge solution based on unique unidirectional technology.
