Implementing Dragos Platform For Ot Monitoring

# Implementing Dragos Platform for OT Monitoring

## When to Use

- When deploying an OT-specific network detection and response (NDR) solution for industrial environments
- When needing threat intelligence-driven detection against known ICS threat groups (VOLTZITE, CHERNOVITE, KAMACITE)
- When building an OT SOC capability with purpose-built industrial security tooling
- When requiring asset discovery and vulnerability management alongside threat detection in a single platform
- When integrating OT security monitoring with an enterprise SIEM (Splunk, Sentinel, QRadar)

**Do not use** for IT-only network monitoring without ICS components, for endpoint detection and response (EDR) on OT workstations, or for environments standardized on Claroty or Nozomi (see respective skills).

## Prerequisites

- Dragos Platform license and deployment package
- Network TAP or SPAN port at OT network boundaries (one sensor per monitored segment)
- Dragos sensor hardware (physical appliance) or virtual appliance meeting minimum specifications
- Firewall rules allowing sensor-to-Dragos-SiteStore communication (encrypted, outbound only from OT)
- Dragos Knowledge Pack subscription for threat intelligence updates

## Key Concepts

| Term | Definition |
|------|------------|
| Dragos Platform | Purpose-built OT cybersecurity platform with asset visibility, threat detection, and vulnerability management for ICS environments |
| Knowledge Pack | Dragos threat intelligence update containing detection analytics for new threats, malware, and vulnerability exploits specific to ICS |
| SiteStore | Dragos central management server aggregating data from all deployed sensors across a site |
| VOLTZITE | Dragos-tracked threat group targeting energy sector OT environments, exfiltrating GIS data and ICS network diagrams |
| PIPEDREAM/INCONTROLLER | Modular ICS attack framework developed by CHERNOVITE, targeting Schneider/OMRON PLCs and OPC UA servers |
| Neighborhood Keeper | Dragos community defense program sharing anonymized threat data across participating OT environments |

## Common Scenarios

### Scenario: Detecting VOLTZITE Reconnaissance in Energy Utility

**Context**: A Dragos sensor deployed at an electric utility detects unusual OPC UA browsing activity and exfiltration of device configuration data from an engineering workstation.

**Approach**:
1. Review the Dragos notification for MITRE ATT&CK ICS technique mapping
2. Identify the source host performing OPC UA browsing (check if it is an authorized engineering workstation)
3. Check Dragos threat intelligence correlation for VOLTZITE TTPs
4. Examine the scope of data accessed (GIS data, network diagrams, ICS configuration files)
5. Isolate the compromised workstation from the OT network
6. Check for lateral movement indicators to other OT systems
7. Engage Dragos Professional Services if threat group attribution is confirmed
8. Report to CISA as a critical infrastructure cyber incident

**Pitfalls**: Do not ignore OPC UA browsing alerts as false positives -- VOLTZITE specifically uses this technique for pre-positioning. Ensure Dragos Knowledge Packs are current to detect the latest VOLTZITE indicators. Do not reimage the compromised workstation before collecting forensic evidence.
