ICS/OT Penetration Testing
Specialised security testing for Industrial Control Systems and Operational Technology environments.
The security of operational technology (OT) and industrial control systems (ICS) is crucial for maintaining the integrity of both IT networks and critical infrastructure.
OT and ICS are just as important as traditional IT networks. These systems often act at critical points in the supply chain and drive essential day-to-day operations of a business. In addition, OT often leaves weak entry points into the IT network, so securing OT complements and reinforces the security of IT.
At Cyber Citadel we don't rely just on automated toolboxes such as vulnerability scanners; our experts draw on their knowledge and expertise to rigorously test ICS and OT environments, keeping in mind business logic and risk-based prioritization. We will also strive to minimize disruption to any business operations.
Our approaches are smart, specific, and seamless. We identify vulnerabilities without disrupting operations or compromising the safety of personnel or equipment.
ICS/OT Testing Areas
SCADA & PLC Security
Assessment of SCADA systems, PLCs, RTUs, and other control system components for vulnerabilities and misconfigurations.
Industrial Protocol Analysis
Testing of protocols including Modbus, DNP3, OPC UA, EtherNet/IP, and PROFINET for authentication and integrity issues.
IT/OT Boundary Testing
Assessment of network segmentation, firewalls, and data diodes that separate your IT and OT networks.
Safety System Review
Evaluation of Safety Instrumented Systems (SIS) to ensure they cannot be tampered with or bypassed by an attacker.
Our Specialized Approach
Human-led Testing
Our testers use human ingenuity and specialised knowledge of ICS/OT environments to uncover vulnerabilities that automated tools miss.
Specialized Tools and Tactics
We use proprietary attack techniques and tools specifically designed for industrial control system testing.
Minimized Risk of Disruption
Traditional testing methods can cause systems to become unresponsive or fall offline. Our techniques start with a passive approach, gradually increasing in intensity to minimize any risk to operational systems.
