Industrial Cyber Security for Oil & Gas

OT Asset Visibility Solution

Limited visibility across ICS environments made it difficult for the client to understand and prioritise OT cyber risk.

Client Context

An oil and gas operator with distributed ICS environments seeking to improve OT risk posture ahead of a planned technology investment programme.

Ask / Requirement

The oil and gas sector client engaged SIS to design an OT asset visibility and monitoring architecture – to clearly understand OT cyber risk across ICS environments and define how OT visibility technology should be securely structured and integrated.

Technology selection alone would not solve the problem without a clear architectural and zoning model aligned to business risk.

What We Delivered

SIS delivered a risk-aligned OT asset visibility architecture, aligned with IEC 62443 and SABSA, including security zone design and reference architectures evaluated against leading platforms – enabling informed technology selection, procurement, and deployment.

By establishing the architecture before selecting a product, the client avoided the common failure mode of deploying visibility tools that generate noise rather than insight – or that introduce new risk through poor integration.

Outcome

The client proceeded to procurement and deployment with a clear, risk-grounded architecture in place. Technology investment was purposeful and aligned to actual risk exposure, rather than driven by vendor capability alone.

Technical vulnerability
and risk assessment of
OT infrastructure

Via a technical vulnerability and risk assessment of OT infrastructure for a gas pipeline company, SIS successfully assisted the gas pipeline company to understand their current-state risk posture in order to determine what an appropriate risk appetite (risk level) is, and the prioritisation of mitigation actions in order to reduce the level of risk exposure to cyber threats.

SIS conducted a risk assessment of our operational technology environment and we were very impressed with their approach, methodology, execution, and delivery. They are adaptable, technically astute, and demonstrated a strong ability to fully understand business requirements specific to the oil and gas sector.
PMO and GRC ConsultantOil and Gas
The project provided our organisation with a clear view of our cyber security maturity and highlighted the range of threats that could impact our systems at any time. As a result of the assessment, several mitigation steps have already been implemented based on SIS’ key recommendations.
SCADA and EMS ProgrammerEnergy Interconnection
SIS delivered an Information Security Management System framework that ensured governance was appropriately embedded across ICT operations, including business critical control systems. This significantly strengthened our audit compliance posture against recognised industry standards.
