How do I know if my operational technology is at risk?

Your operational technology may be at risk if you cannot clearly answer basic questions about assets, connectivity, access and recovery. OT risk is not always visible from day-to-day operations. Systems may appear stable while containing weaknesses that only become obvious during an incident.
Warning signs include incomplete asset inventories, unknown network connections, shared accounts, unsupported systems, unmanaged remote access, lack of tested backups, no OT incident response plan, poor documentation and limited separation between IT and OT networks.
Questions to ask
Can you identify your most critical OT assets? Do you know which suppliers have remote access? Are firewall rules reviewed? Are engineering laptops controlled? Are backups offline and tested? Do operators know what to do if a cyber incident affects the control network? Are changes recorded and approved?
If the answer to several of these questions is no, your organisation may be carrying avoidable cyber risk.
Risk is about likelihood and impact
Not every vulnerability has the same importance. A weakness on a non-critical standalone system may be lower priority than weak remote access into a control network. The right approach is to understand which systems matter most and which pathways could create the greatest impact.
How ControlShield can help
ControlShield can perform an OT cyber security posture assessment to identify gaps, prioritise risk and recommend practical improvements. We can review documentation, conduct workshops, assess architecture, examine remote access, support asset inventory development and produce a clear improvement roadmap.
Our assessments are designed for industrial environments and can be aligned to IEC 62443, CAF, OG86 or your internal governance requirements.
Contact ControlShield for a practical OT cyber risk assessment and clear next steps.
