An article titled Jumpstart Cyberthreat with High-Level Risk Assessments authored by exida Cyber engineer Patrick O'Brien has been published in Valve Magazine.
Cybersecurity is a major concern for industrial control systems, but the continually evolving nature of the field and the sheer amount of existing threats and vulnerabilities make it a daunting task to figure out where to begin addressing cybersecurity concerns.
It could be argued that currently the biggest cybersecurity challenge for industrial networks is not the multitude of cyberthreats, but the inability to effectively identify and mitigate cybersecurity risk. Inaccurately identifying the risks can result in the use of a system that is both costly and still vulnerable to attack. This article will focus on a practical example for a high-level risk assessment that forms the basis for effective management of cybersecurity risk.
