Entities responsible for critical infrastructure—energy, health care, transportation, telecommunications, and financial services are confronting an increasing wave of cyberthreats that have significant economic and public safety consequences. Most Industrial Control System (ICS) and Supervisory Control and Data Acquisition (SCADA) systems rely on legacy technology and narrow cybersecurity options. This limitation increases the difficulties of patch management and continuous operations, and the downtime of significant functions may pose safety issues and huge financial damages.
