Whitepaper: Secure OT/IT Integration for Critical Infrastructures

Protect critical infrastructures with physical separation and controlled data exchange.

‍The integration of OT and IT increases efficiency but also introduces cyber risks. Where OT systems used to operate in isolation, they are now more frequently connected to IT networks, increasing the likelihood of cyberattacks. This can lead to process disruptions, data loss, or even physical damage. MagiCtwin offers a solution to securely integrate OT and IT without compromising operational continuity.

Through physical separation and controlled data exchange, OT remains protected against attacks via IT, while monitoring and analysis continue safely. MagiCtwin is fully developed in Europe, ensuring maximum security and digital sovereignty.

// OT/IT Integration: Balancing Efficiency and Security

OT and IT play vital roles in sectors such as energy, water management, and industry. IT manages data, communications, and software, while OT controls physical processes like power generation and production lines. Linking these systems enables better monitoring and data analysis, leading to improved decision-making and process optimization.

‍

However, this integration also introduces risks. IT systems are regularly exposed to malware, ransomware, and other cyber threats. Once OT and IT are connected, these threats can disrupt operational processes with potentially severe consequences. Attacks like Stuxnet have shown that cybercriminals can exploit IT breaches to sabotage OT systems. Therefore, a balanced OT/IT integration is essential: optimal connectivity without compromising security.

// How critical infrastructures remain secure

Cyberattacks pose an increasing risk to critical sectors such as energy, drinking water, oil and gas, and nuclear infrastructure. Hackers attempt to gain control over critical systems, which can lead to outages, dangerous situations, and economic damage. A data diode can play a significant role in making external attacks far more difficult. Below is an explanation of how this works for each sector.

Energy

Power plants and grid operators are increasingly exposed to cyber threats. A successful attack on SCADA systems or external monitoring software can lead to disruptions or even large-scale outages. To securely share operational data with monitoring centers without giving cyber attackers access to critical infrastructure, the MagiCtwin Data Diode is deployed. It enforces strictly one-way traffic, ensuring that essential data remains available while keeping the OT network protected from external threats.

Drinking water

Water treatment facilities are becoming increasingly digitized, which also brings new security risks. An attack in which parameters such as chlorine or pH levels are altered can have serious consequences for public health. In the past, there have been incidents where hackers gained access to industrial control systems. To mitigate such threats, the MagiCtwin Data Diode ensures that real-time water quality data can be securely shared with regulators, while preventing any external access to the OT network.

// Wait… there’s more!

Did you know that one-way traffic (physical separation) is still the only proven method to completely eliminate digital attacks?

What is physically impossible does not need to be defended digitally. In the whitepaper, you will learn why network segmentation is crucial for critical infrastructures. But there’s more:
