Executive Decision Brief
Operating separate IT and OT security operations creates dangerous visibility blind spots during cross-domain cyber attacks. This blueprint outlines how industrial operators architect a converged 24/7 Security Operations Center (SOC) capable of ingesting both enterprise IT telemetry (EDR, cloud, identity) and industrial network signals (Modbus, DNP3, CIP) into a unified correlation engine.
Strategic Takeaways for Executive Leadership:
- Eliminates security silos between enterprise corporate IT and plant operations teams.
- Ingests passive OT network sensors (Nozomi, Claroty, Dragos) into a centralized enterprise SIEM/data lake.
- Builds specialized detection engineering rules for unauthorized PLC firmware changes, abnormal setpoint modifications, and baseline deviations.
- Establishes collaborative incident triage playbooks connecting SOC analysts directly with plant engineers.
Target Executive Audience:
Unified Event Correlation Detects Multi-Stage Cyber Attacks Pivoting from IT to OT
A sophisticated attack rarely begins inside the OT network. It starts with a compromised employee identity in the enterprise domain, followed by VPN access to the IDMZ, and finally unauthorized commands sent to industrial controllers.
Only a converged SOC with unified cross-domain telemetry can correlate an unusual corporate login at 2:00 AM with a simultaneous PLC ladder logic modification in a remote substation.

Executive & Technical Questions
How does a converged SOC handle sensitive plant operational data without risking IP leakage?
All telemetry is parsed locally on dedicated edge collector appliances, stripping proprietary operational values while forwarding only security metadata and protocol headers to the SIEM.
