Visualizing Industrial Threats- Using Analytics to Secure IoT/OT Environments

Why Visualization Matters in OT Security

• Industrial networks are complex and fast-changing.

• Visual tools make detecting anomalies, misconfigurations, or active threats easier.

• Even non-technical stakeholders can understand visual dashboards.

Real-Time Monitoring Dashboards

What to Track:

• Device health & firmware status

• OT traffic flow between network zones

• Unauthorized device attempts

• Protocol anomalies (e.g., strange Modbus commands)

Tools to Use:

• Grafana, Splunk, ELK Stack, or SCADA-native tools

• Custom interfaces using Node-RED or Kibana

Security Incident Visualization

• Map threat activity with heatmaps, attack paths, and time-based animations

• Show lateral movement in the network (e.g., from IT to OT)

• Include interactive logs for forensic analysis

User & Entity Behavior Analytics (UEBA)

• Use machine learning to flag unusual user or device behavior

• Examples:

  • A sensor communicating at strange hours

  • A technician logging in from a new location

• Correlate with SIEM tools to prioritize alerts

Predictive Security with Data

• Use historical OT data to predict:

  • Equipment failures linked to cyber manipulation

  • Attack patterns (based on frequency, origin, and targets)

• Combine IoT data and threat intelligence feeds for contextual alerts

Building Your Security Visualization Strategy

• Identify key data sources: OT traffic, authentication logs, sensor data

• Centralize with a data pipeline: Use brokers like MQTT or OPC UA with secure forwarding

• Create dashboards by role: Engineers, CISOs, and incident responders need different views

• Test alert thresholds: Avoid alert fatigue but don’t miss critical signs
