We tend to be familiar with “Information Technology” and the efforts organisations put to secure the data, applications and systems we refer to IT. Operational Technology is less understood and only with the adoption of IoT, and more importantly, the attacks on infrastructure critical systems has the issue of securing OT become a point of contention starting with those is responsible for IT-OT or OT-IT converged systems. In this PodChats for IoT, we speak to Richard Farrell, Asia-Pacific Director for Cloud, Data and Digitalization, on securing IT-OT convergence.1.       What is IT-OT convergence? What is the implications to businesses?2.       Should it be considered IT-OT convergence or IT-OT integration?3.       How has the growing adoption of 5G and IoT technologies leading to the convergence (integration) of IT and OT systems? 4.       How should these be connected to the IT systems be secured? 5.       Please name 3 best practices for a holistic IT/OT cybersecurity programme?
