Protecting telemetry data in state-wide critical infrastructure network

Industry

  • Power grid operator

  • Critical infrastructure

Technology stack

  • Telemetry hardware

  • IEC-104 compliant meters

  • TSO Central Dispatch system

Regulations

  • Internal security policies and IEC standards

Technology requirements

Secure data flow

Normalisation, accumulation, and transmission of sensitive telemetry signals to the core dispatch systems.

Data availability

It's crucial to to have a backup "source of truth" system capable of accumulating all the data.

SCADA integration

Data delivery to SCADA/dispatch systems within central network in a secure and controlled fashion.

Challenges

Legacy

Most of the hardware emitting telesignals is heavily outdated legacy equipment, typically compatible only with a limited number of devices gathering and transmitting telemetry data signals.

Telemetry security

Telemetry data signals are sensitive data and must be transmitted securely.

No direct communication

There is no direct communication link between power distribution stations and central dispatch system, so hybrid GSM/private/transit network combinations are used.

Unavailable cellular networks

Available public cellular networks are unreliable in some areas.

Results and outcomes

Integrating data protection into legacy system

Updating legacy systems to comply with data security regulations is a laborious process. We already worked with state-owned TSOs, ICS/SCADA systems, and can help you too.
