The post discusses the limitations of Intrusion Detection Systems (IDS) in monitoring network behavior without verifying physical process changes in Operational Technology (OT) environments, emphasizing that combining IDS with process-level monitoring at Level 0 provides comprehensive detection, operational clarity and regulatory compliance by confirming actual physical impacts of cyber incidents.

This post discusses the limitations of traditional OT cybersecurity tools that rely on network-layer monitoring, highlighting the risks of compromised control logic and data manipulation at the process layer, and presents SIGA's process-oriented cybersecurity approach using out-of-band electrical signal data and machine learning to provide CISOs with reliable visibility and decision support for operational resilience in critical infrastructure and manufacturing environments.

Power utilities must comply with NERC PRC-005 by verifying the physical operation of protection system relays and breakers through independent Level Zero instrumentation. This ensures real-world actions match commands, addressing cybersecurity vulnerabilities and regulatory obligations while avoiding costly penalties.
