A Unidirectional Reference Architecture
Traditional IT-style advice fails to address the threats facing modern power plants. Because control systems in power plants operate large, complex, dangerous physical processes and equipment, there is a need for a preventative approach to protecting power generation. If damaged, turbines and transformers cannot be “restored from backups”, and intrusion detection, response and remediation can interrupt the reliable continuity of services.
Such compromise to power generation plants is unacceptable.
In this paper we discuss modern reference architecture for defense-in-depth network protection of power plants, eliminating external remote cyber risks to protected, reliability-critical networks, including 4 use cases:
- Safe IT/OT integration
- Turbine vendor monitoring
- Protecting relay and safety networks
- Control Center Communications
