Active Cyber Defense for Energy Infrastructure

The energy sector is a prime target for sophisticated cyber threats, making traditional passive security measures insufficient to protect critical national infrastructure. To safeguard power grids and utility networks, security professionals must shift from passive monitoring to proactive, active defense. This text-based course guides you through the core principles of active cyber defense tailored specifically for energy systems. You will transition from understanding basic security concepts to analyzing threat intelligence, mapping adversaries, and implementing modern protective measures across operational technology (OT) and information technology (IT) environments. What you'll learn: Understand the foundational differences between IT and OT security in energy infrastructure; Identify modern threat actors, vectors, and common attack methodologies targeting utilities; Apply the MITRE ATT&CK framework for ICS to map and anticipate adversary behavior; Implement zero-trust principles and network segmentation to isolate critical grid assets; Practice proactive threat hunting techniques using log analysis and network indicators; Develop incident response readiness plans tailored for energy sector environments. The course begins with essential terminology and the unique architecture of energy systems, before moving into proactive defense strategies, threat hunting, and modern security frameworks. Through clear written explanations and realistic scenarios, you will build a solid foundation in securing critical infrastructure. This course is designed for IT professionals, aspiring security analysts, and engineering staff new to cybersecurity who want to specialize in protecting energy systems. No prior cybersecurity experience is required. Start reading today to build the essential skills needed to defend critical energy infrastructure against modern cyber threats.
