Unidirectional Security Gateways

The Industrial Security Podcast Hosted by Andrew Ginter

Industrial systems work 24/7 to keep our lives ticking. But what happens when those systems are threatened? The Industrial Security Podcast takes a deep-dive into the most pressing issues in SCADA technologies today. Each new episode features a leading voice in the world of industrial control systems security. You'll hear from executives, engineers, researchers and more, each with their own unique take the unique challenges of OT security.

SEC-OT is a methodology and set of best practices that document what thoroughly-secured industrial sites actually do to protect their networks. While most industrial sites practice IT Security (IT-SEC) whose focus is to “protect the information”, the focus at secure industrial sites is protecting the safe, reliable, continuous and correct operation of the physical, industrial process, not just protecting information. The strategy for SEC-OT is physical protection of control-critical networks from information/attack flows, not just IT-SEC-style software protection.

The New Gold Standard for OT Security Monitoring: Waterfall for IDS

Waterfall enables safe intrusion detection and security monitoring for OT networks. Leading OT intrusion detection system and SIEM vendors all partner with Waterfall. This is the new gold standard for security monitoring at industrial enterprises. Waterfall’s hardware-enforced products enable IDS sensors and security monitoring systems to connect simultaneously to both IT and OT networks, with no risk of compromise to industrial networks. Waterfall’s physical protection for monitored OT networks reliably defeats the most sophisticated attacks.

Waterfall Protects Hyundai Steel from External Cyber Threats

The modern manufacturing industry is facing an increased attack surface. With the increased connectivity of digital devices inside a smart manufacturing plant comes a remarkable increase in attack surface. To avoid the costly turn-arounds, the modern, highly–connected manufacturing plant needs a solution to keep attackers out while simultaneously analyzing and aggregating data for plant optimization.

Securing Power Generation: A Unidirectional Reference Architecture

OT networks at power generation sites operate large, complex, and dangerous physical processes and therefore need for a preventative and disciplined approach to protecting the network perimeter. In this paper, we discuss modern reference architecture for defense-in-depth network protection of OT networks at power plants, eliminating external cyber risks and enabling disciplined control to reliability-critical networks, including 4 use cases:

• Safe IT/OT integration
• Turbine vendor monitoring
• Protecting relay & safety networks
• Control Center Comms
