2. Robert M. Lee’s tweet on operational technology and industrial control systems

Robert M. Lee, co-founder and CEO of Dragos, shared his video where he gives an introduction to operational technology (OT) and industrial control systems (ICS). He noted that attribution and bias in ICS acts as a hinderance to security analysis. Analysing threats and how to address those threats forms the basics for ensuring cybersecurity in ICS, he added.

Lee described the stages of cyberattacks including planning an attack, and development and execution of an attack. To defend cyberattacks, defenders should learn the business needs and understand the ICS closely. They should also be able to transfer intelligence to user and communicate about information on threats to users effectively, Lee noted.
