The convergence of operational technology (OT) and enterprise IT environments has significantly increased the cybersecurity risks for electric power infrastructure. As Bulk Electric System (BES) operators modernize their grids, attackers are increasingly using lateral movement to pivot from initial entry points toward high-value operational assets. Traditional security measures focusing on north-south traffic are often insufficient, making visibility into internal east-west traffic and specialized industrial protocols like DNP3 and Modbus essential for detecting stealthy intrusions.
To address these challenges, regulatory standards like NERC CIP-015 are emphasizing the need for robust monitoring within Electronic Security Perimeters (ESPs). Modern security platforms, such as TrendAI Vision One, provide the necessary OT-aware visibility and AI-driven analytics to identify anomalous communications across complex infrastructure. By prioritizing internal network monitoring, discovery of unmanaged assets, and cross-environment correlation, security leaders can effectively stop lateral movement and ensure the reliability of critical grid operations.
