The separation of IT and OT introduces some interesting security challenges. Due to the nature of ICS, COVID-19 forced IT at Wesfarmers WesCEF to install a number of network changes which required a fast-moving OT environment on a skeleton crew.

• Maintaining stakeholder engagement and awareness throughout a period of uncertainty.
• Providing centralised management and change control for a reduced IT and OT
