Furthermore, the process of licensing plays a vital role in cybersecurity. In an era where industrial control systems are frequent targets of cyberattacks, using official, licensed software is a primary line of defense. Users searching for unauthorized "cracks" or shared license keys often expose their workstations to malware, ransomware, or trojans embedded in pirated installers.
