Guide to Methods for Protecting Against Cyber Attacks on Industrial Infrastructure.

Industrial infrastructure underpins the operation of many key sectors of the economy, such as energy, transportation and water supply. However, the increasing number of cyber attacks on operating and network systems in the industrial sector is forcing advanced protection strategies. In this article, we take a look at the most common threats, effective protection methods and technologies that can help secure industrial infrastructure from attacks.

Key findings:

1. Cyber threats in industrial infrastructure include ransomware, malware and attacks on SCADA control systems.
2. Protection requires the integration of IT and OT and the use of a multi-layered security strategy.
3. Advanced technologies, such as IDS/IPS systems, next-generation firewalls and SIEM, effectively minimize risks.
4. Regular audits and penetration tests identify and eliminate security vulnerabilities.
5. Employee education and constant monitoring of systems are key to minimizing the risk of cyber attacks.

Why is industrial infrastructure a target for cyberattacks?

Industrial infrastructure, including systems for managing energy, production, transportation or water supply, is an attractive target for cybercriminals. One reason for this is its critical importance – disruption of such systems can cause not only downtime for companies, but also negatively affect the daily lives of citizens. In addition, because of the integration of IT and OT, cybercriminals gain new attack opportunities by exploiting vulnerabilities in both environments. Many of the operating systems used in industry are based on older technologies that were not designed with modern threats in mind. Outdated systems and lack of regular updates make them vulnerable to various types of attacks. Additionally, insufficient cyber security training for employees can lead to unknowingly opening the door for criminals, such as by clicking on infected links.

Key threats to industrial infrastructure

1. Ransomware – One of the most dangerous types of attacks, which involves encrypting data or systems and then demanding a ransom to recover them. Ransomware attacks can cripple entire production lines and SCADA systems, leading to costly downtime.
2. Attacks on SCADA – SCADA systems, responsible for controlling industrial processes, are particularly vulnerable to attacks due to their critical operational importance. Taking control of SCADA can result in the disruption of an entire plant.
3. Malware dedicated to OT – Malware specifically designed to disrupt industrial processes, such as Stuxnet, shows how much damage such threats can do.
4. DDoS attacks – These involve overloading a network and making it inoperable. In the industrial sector, DDoS attacks can make it impossible to monitor key processes.
5. Unauthorized access – Exploiting security weaknesses, such as outdated passwords or lack of network segmentation, allows systems to be taken over.

Effective methods to protect industrial infrastructure

1. Network segmentation – By dividing the infrastructure into isolated segments, you can limit the spread of an attack if one segment is breached. This protects critical systems from access from less secure areas of the network.
2. Access management – Implementing policies based on the principle of least privilege ensures that users and devices only have access to the resources they need to do their jobs.
3. Regular software updates – Ensure that all systems, including SCADA and IoT devices, are updated and free of known security vulnerabilities. Updates should be performed in a controlled manner to minimize the risk of interruptions.
4. Real-time monitoring – The use of advanced monitoring systems allows for the rapid identification of suspicious activity, enabling immediate response.
5. Data Backup – Regular backups of data critical to industrial operations allow systems to quickly recover from a disaster or ransomware attack.

Technologies to support safety in industry

1. IDS/IPS – Intrusion Detection/Prevention Systems identify and block unauthorized access attempts and network attacks. Thanks to advanced algorithms, these systems can detect even subtle breach attempts.
2. Next-generation firewalls – NGFWs offer advanced network traffic control, filtering data based on applications, users and behavior. They are crucial in protecting industrial systems from malicious traffic.
3. SIEM systems – Security incident management tools allow real-time correlation of incidents, making it easier to identify threats. SIEM also helps analyze incidents and their causes.
4. Data encryption – Protects data from being intercepted and read by unauthorized persons. Encryption should be used in both data transmission and storage.
5. Penetration testing – Regularly conducting simulated attacks helps identify security weaknesses and fix them before cybercriminals can exploit them.
