Leveraging existing process safety risk assessment techniques can help organizations effectively manage cybersecurity risks.
Cybersecurity has become a credible threat to process safety. Today, 70% of industrial automation and control systems (IACS) can be accessed remotely, increasing the vulnerability of the chemical process industries (CPI) to cyberattack. The consequences of cyberattacks are well understood for business networks (e.g., data theft, denial of service, etc.). However, cyberattacks on IACS can have more severe consequences, because they control physical systems. This article explores how cybersecurity is changing process safety, considers the impact of cybersecurity incidents on traditional strategies for safeguarding and risk assessment, and introduces key steps to manage cybersecurity risk.
