Industrial control system (ICS) security is certainly not a new concept, but over the past 18 months, its status has risen to the top of organizations’ priority lists. This is, in large part, due to the high-profile ICS attacks that have dominated news headlines of late.

Although the group behind the attack specifically targeted the company’s information technology (IT) systems, Colonial’s operational technology (OT) systems were affected in the process because of their reliance on IT infrastructure. The cyberattack served as an eye-opening example of the significant security risks associated with IT/OT convergence.
