Detect anomalies in DNP3 communications used in SCADA/ICS systems by monitoring unauthorized control commands, firmware update attempts, protocol violations, and deviations from baseline traffic using deep packet inspection and machine learning approaches. Use when securing energy-sector or other OT/ICS networks, investigating suspicious DNP3 master/outstation activity, or building an anomaly-based IDS for industrial control traffic.

When to use

• When monitoring SCADA systems in the energy sector where DNP3 is the primary protocol
• When building detection rules for DNP3-based attacks against RTUs and substations
• When investigating suspected unauthorized control commands sent via DNP3
• When deploying IDS with DNP3 deep packet inspection at utility substations
• When responding to alerts from OT monitoring platforms about DNP3 traffic anomalies

When not to use

• non-DNP3 protocol monitoring
• DNP3 Secure Authentication configuration
• protocol-agnostic network anomaly detection
