Summary
This Technical Brochure presents a comprehensive analysis of Security Operations Centers (SOCs) in the electric power industry, drawing on a global survey of 84 professionals across 28 countries and on case studies from five regions. It examines current SOC architectures, IT-OT integration challenges, the impact of new regulations such as NERC CIP-015-1 and the NIS2 Directive, and the role of AI/ML and automation in detection and response. The brochure highlights critical blind spots — notably Level 0 (physical-layer) security — and offers practical recommendations for executives, security leaders, and technical professionals to design, implement, and mature SOCs that strengthen situational awareness and resilience against evolving cyber threats.
