Who Owns OT Cybersecurity?

Cybersecurity experts have long played a significant role in any information technology
(IT) department. However, an increase in cyberattacks targeting operational technology
systems raises the question: Who is in charge of operational technology (OT) security, and
what is needed to prevent, detect and respond to new attacks?
The 2021 attack on Colonial Pipeline demonstrated the effect a cyberattack can have on
operational environments and the supply chain, delaying the 1.4 million barrels of fuel
delivered daily up and down the East Coast. Before the age of the internet, the Industrial
Control Systems (ICS) that ran industrial operations were more likely to be “air gapped,”
or disconnected entirely from the outside world. Today, these systems are connected and
networked across the business, expanding the attack surface and exposing new
vulnerabilities that threat actors are looking to exploit.
