A CPS IDS (Cyber-Physical Systems Intrusion Detection System) monitors and protects the critical intersection of digital networks and physical infrastructure — where a cyber attack can cause real-world physical harm to people, equipment, and the environment.
Cyber-Physical Systems (CPS) are environments where digital computation, networking, and physical processes are tightly integrated. Power grids, water treatment plants, manufacturing facilities, transportation networks, and oil pipelines are all CPS — every digital action has a potential physical consequence.
A CPS IDS goes beyond detecting network anomalies — it understands the physical context of those anomalies. When an OT IDS detects an unusual Modbus write command, a CPS IDS correlates that with the physical process state: Is this command outside the safe operating envelope? Could it cause a physical hazard?
NETRUDER functions as both an OT IDS and CPS IDS, combining deep protocol inspection with Purdue Model-aware asset classification and process-context enrichment to deliver the most accurate threat detection for industrial and critical infrastructure environments.
Physical process awareness and cyber threat detection in a unified platform
Correlates cyber events with physical process state — detecting attacks that manipulate setpoints, bypass interlocks, or alter control logic.
Monitors communication across all Purdue Model levels — from field devices (L1) to enterprise systems (L4/L5) — detecting lateral movement between cyber and physical layers.
AI models learn the interaction between digital commands and physical outcomes to detect deviations that indicate tampering or compromise.
Specialized detection for safety instrumented system (SIS) tampering, unauthorized override attempts, and inhibit-response attacks targeting physical safety layers.
Understands 30+ OT/ICS protocols — IEC 61850, DNP3, Modbus, PROFINET — and correlates events across heterogeneous CPS environments.
Detects threats that traverse IT/OT boundaries — malware moving from enterprise networks into operational technology and cyber-physical systems.
Real-world cyber-physical attack patterns observed in critical infrastructure
Sophisticated malware targeting PLCs and SCADA systems to alter physical processes while reporting normal status to operators.

Oil & Gas, ManufacturingReplaying legitimate industrial protocol traffic at inappropriate times to confuse operators or trigger unintended physical actions.
All SectorsOT IDS and CPS IDS are closely related. NETRUDER is both — here's how the capabilities compare.
