Case Study: SOC Convergence for Remote Offshore OT Environments
Offshore Facility in the Middle East (GCC)
Preserving log integrity and structure for SIEM correlation
Real-time OT event forwarding without inbound connectivity risk
Integrating OT telemetry into centralized SOC workflows
Need / Problem / Context
Secure & rich OT Event Forwarding to a Centralized Cisco Splunk SIEM
A major offshore oil & gas facility in the Gulf region needed to provide its centralized onshore SOC with real-time visibility into cybersecurity events occurring within the offshore OT environment.
Operational alarms, security logs, and system events generated by industrial assets had to be forwarded to the organization’s Cisco Splunk SIEM platform to enable centralized monitoring, correlation, and threat detection.
However, the OT network controlling offshore operations had to remain strictly isolated to prevent any remote cyber intrusion that could disrupt production or compromise safety.
The challenge was to securely transmit OT security telemetry to Cisco Splunk — while maintaining a strict one-way security boundary and preserving the integrity of the industrial control environment.
Solution Deployed
A Cyberium unidirectional gateway architecture was deployed between the offshore OT network and the onshore SOC to securely forward security events while maintaining strict physical separation. It enables reliable OT security telemetry transfer for centralized monitoring and threat detection — without exposing offshore systems to inbound cyber risks.
2x OWA 3U pack @ 1 Gbps
Two unidirectional gateways were deployed to securely forward OT security events while preserving strict physical separation between offshore operations and the central SOC.
High-Availability℗ Setup
Cyberium patented High Availability mechanisms ensure uninterrupted event forwarding and eliminate any single point of failure for this critical security monitoring flow.
Standard (SFTP)
+ HTTP/S API Connectors
Security events and operational logs are exported through standard secure protocols, enabling seamless integration with the centralized SOC and SIEM environment.
Splunk Configuration Deployment
Splunk ingestion pipelines and field mappings were configured to ensure offshore OT events are fully interpretable and actionable within the centralized SIEM platform.
Outcomes & benefits
By extending SOC visibility to offshore OT environments, the organization improved incident detection speed, reduced potential operational disruptions, and increased the value of its existing cybersecurity monitoring infrastructure.
Faster threat detection by providing the SOC with real-time visibility into offshore OT security events
Reduced average operational outage time through earlier incident identification and response
Maximized return on investment of the existing SOC and SIEM infrastructure by extending its visibility to offshore OT assets
Secure integration of remote operational environments into centralized cybersecurity monitoring
