OT / ICS & Critical Infrastructure Security
Hardening the Operational Layer: SCADA, PLC, and IIoT Resilience
Purpose
To engineer a robust security architecture for Industrial Control Systems (ICS) where "Availability" and "Safety" are the primary directives. We specialize in the convergence of IT and OT, implementing defensive measures that neutralize lateral movement without inducing latency or disrupting deterministic real-time processes.
Outcome
A "Defensible Plant Floor" characterized by rigorous Perimeter Segmentation, deep-packet inspection of industrial protocols (Modbus, DNP3, Profinet), and high-fidelity risk visibility. We ensure your PLC/SCADA environment is resilient against targeted cyber-physical attacks while maintaining 100% operational uptime.
PLC / SCADA
IT-OT Segmentation
Services Included
PLC / SCADA Risk Quantification
Passive vulnerability research on logic controllers and HMI software to identify unpatched firmware and insecure engineering workstations.
Industrial Network Mapping
Asset inventory and discovery via non-intrusive traffic mirroring to identify ghost assets, rogue IIoT sensors, and unauthorized backdoors.
Purdue Model Segmentation
IT-OT convergence security using DMZs between site operations and enterprise layers with strict firewall and unidirectional gateways.
Industrial Protocol Deep-Dive
Deep packet inspection for Modbus, DNP3, Profinet and others to detect anomalous function codes and baseline deviations.
OT Incident Simulations
Tactical tabletop exercises around high-consequence, cyber-physical scenarios such as ransomware at the SCADA layer.
Functional Safety Alignment
Ensuring security controls do not interfere with Safety Instrumented Systems, emergency shutdowns, or life-safety protocols.
