The dependable operation of critical infrastructure hinges on the availability and security of its operational technology (OT) and industrial control systems (ICS). Often, assets are managed and supervised remotely. However, OT environments frequently lack adequate visibility to detect misconfigurations, operationally significant errors, or cyberattacks.
Several national IT security regulations mandate the establishment of an end-to-end system for threat monitoring and detection. This system ensures continuous monitoring of critical infrastructure, facilitating early identification and mitigation of potential attacks.
Critical infrastructures require an OT system that:
- Establishes comprehensive end-to-end visibility of devices (hosts), connections, and communication behavior
- Conducts ongoing analysis of the entire communication
- Detects, record, and reports anomalies in communication behaviour in real-time
These capabilities empower OT security engineers to respond swiftly and proactively to both attacks and technical error conditions.
