Cybersecurity at the Chvaletice Power Plant: OT and IT networks under close scrutiny of a security audit

Cybersecurity has been a long-term priority for us. It plays a crucial role in ensuring the reliable and safe operation of our power plant. Thanks to Soitron’s professionality and technical solutions such as Soitron Security Sensor, we have improved our in-depth overview of our OT and IT networks even further. Solutions tailored to our specific needs help us minimise potential risks related to outages while strengthening the security of the energy system.

Background

The Chvaletice Power Plant is acutely aware of the critical importance of the cybersecurity for its operational technology (OT) as it is the foundation of its critical infrastructure. They also put emphasis on information technology (IT) that supports its business and administrative processes. While the OT network is responsible for controlling and monitoring key power generation processes, the IT networks ensure the smooth functioning of the organisation as a whole. Targeted solutions for protecting both OT and IT systems allow the plant not only to guarantee uninterrupted and reliable operation, but also to demonstrate a responsible approach to meeting regulatory commitments. As part of its efforts to enhance cybersecurity across its networks, the power plant sought solutions to improve OT and IT systems protection. In this endeavour, we acted as their technological and consulting partner.

Project implementation process

deployed the Soitron Security Sensor—a security solution designed to analyse network traffic and file security. A single physical device integrates several security products tailored to detect advanced threats and provide network visibility. These products are always customised to the specific needs of the customer. In this case, we combined solutions suited for analysing both OT and IT networks: FlowMon, Nozomi Guardian, and Cisco ICS CyberVision.

The Security Sensor was physically installed on-site at the power plant. Once deployed, the solution monitored and analysed network traffic within both the OT and IT environments. Based on the collected data, our experts prepared a final report that included findings, recommendations, and further development opportunities. With the audit the customer learned how well it is protected against potential security incidents and what are the most suitable technologies for its OT and IT environments.

Customer Profile

The Chvaletice Power Plant is part of the Sev.en Česká Energie a.s. group. With its strategic location, it serves as the energy hub of Eastern Bohemia and is the only power plant in the region certified to stabilise the power system voltage fluctuations, restore power supply after a system collapse, and operate in island mode. The plant ensures a stable supply of electricity from local sources. Its four units generate electric power to cover both base-load (24 hrs) consumption and peak demand (12 hrs) with dynamic output ranging from 100 to 840 MW.
