Substation Control System Security Review
Substations depend on control systems, protection relays and communication links that were rarely designed with today's threats in mind. Our substation engineers review the security posture of your substation control systems (SCS), their communication with the control centre, and all external connectivity: what is lacking, what is outdated and what needs to be improved. The review uses drawings, documents, records and interviews; we don't change anything on live systems.
What's included
- Design security review of substation control system architecture (IEC 61850 station and process bus, gateways, firewalls)
- Review of communication between substations and the national or regional control centre
- Review of all external, remote and vendor connectivity into the substation
- User accounts and access to protection relays, gateways and engineering workstations (from records you provide)
- Use of secure communication where possible (IEC 62351) and IEC 62443 requirements
- Configuration change approval and configuration backup practice
- Security inspection at substation FAT and SAT
- Findings: what is lacking, outdated or to be improved, with priorities
