• Abstract: This manuscript explores the cybersecurity challenges of Operational Technology (OT) networks, focusing on their critical role in industrial environments such as manufacturing, energy, and utilities. As OT systems increasingly integrate with Information Technology (IT) systems due to Industry 4.0 initiatives, they become more vulnerable to cyberattacks, which pose risks not only to data but also to physical infrastructure. The study examines key components of OT systems, such as SCADA (Supervisory Control and Data Acquisition), PLCs (Programmable Logic Controllers), and RTUs (Remote Terminal Units), and analyzes recent cyberattacks targeting OT environments. Furthermore, it highlights the security concerns arising from the convergence of IT and OT systems, examining attack vectors and the growing threats posed by malware, ransomware, and nation-state actors. Finally, the paper discusses modern approaches and tools used to secure these environments, providing insights into improving the cybersecurity posture of OT networks.

  The digitization of all processes and the opening to IoT devices has fostered the emergence of a new formof crime, i.e. cybercrime. The maliciousness of such attacks lies in the fact that they turn users into facilitators of cyber-attacks, to the point of being perceived as the weak link'' of cybersecurity. Knowing how to anticipate, identifying weak signals and outliers, detect early and react quickly to computer crime are therefore priority issues requiring a prevention and cooperation approach.
