Sectors
Oil & Gas
The oil and gas sector connects distributed upstream assets, thousands of kilometres of pipelines, and complex refinery processes. Each segment relies on industrial control systems whose compromise can lead to operational shutdowns, financial losses, or threats to human safety and the environment.
Challenges
Refinery control system security
DCS platforms, Safety Instrumented Systems (SIS), and Emergency Shutdown systems (ESD) require protection without disrupting continuous process operations. The 2017 Triton attack on a petrochemical facility in Saudi Arabia demonstrated that adversaries can target functional safety systems directly.
Pipeline infrastructure protection
SCADA systems monitoring transmission pipelines span hundreds of remote terminal units (RTUs) distributed across vast geographies. The 2021 Colonial Pipeline incident - where the shutdown of a billing and MES system forced a precautionary halt of the entire pipeline - exposed the fragility of fuel supply chains.
Industrial protocols and legacy systems
OT environments in oil and gas rely on specialised protocols - Modbus, OPC UA, HART, Foundation Fieldbus - often without built-in authentication or encryption. Integrating these with modern IT systems demands careful segmentation and traffic monitoring.
Case study
Crude oil transmission infrastructure operator
OT network security audit covering the pipeline SCADA system, pump stations, and metering points - aligned with IEC 62443 and IEC 61511 requirements.
Definition of zones and conduits per IEC 62443, identification of IT/OT separation gaps, and a roadmap for deploying industrial traffic monitoring.
We'll discuss scope, methodology, and timeline.
