The Crucial Role of Cybersecurity in Operational Technology

In an era where Internet Protocol (IP)-based networks and commercial off-the-shelf (COTS) hardware and software are prevalent in process industries, the threat of cyberattacks is on the rise. This paper underscores the criticality of this issue and advocates for a proactive approach to cybersecurity, where industry best practices are integrated into every new and existing system. Cybersecurity incidents present an increased risk to the business, manufacturing processes, and safety. As a result, companies have begun requiring that products and systems used on the production floor comply with industry Operational Technology (OT) cybersecurity codes and standards. However, individual devices and subsystems, modern and legacy, must unite in an allinclusive network ecosystem. Therefore, each company must develop cybersecurity strategies that align with industry best practices and standards as well as the company's risk tolerance level. This paper will focus on key cybersecurity strategies and take a comprehensive approach to implementation, including people, processes, and technology.
