Mr. Pat Larkin:

I do not think so. The chink is perhaps everywhere. The Deputy is right that we need an approach that secures the citadel, the critical parts of the network and where the data resides. Realistically, and without being alarmist, the reality is that in every part of infrastructure, power, utilities, etc., one will find laptops and operational technology, OT, devices that exist that are perhaps are not appropriately controlled or secured. That relentless risk assessment and information security management is trying to identify those points on highly secure, highly critical networks as much as less-secure peripheral networks, to find those vulnerability points and those weaknesses and either secure or remove them. Our experience would be that at the centre of some of the most sensitive and eye-rollingly scary environments, we will find the same weaknesses that the Deputy just outlined. There will be relatively insecure or uncontrolled devices creeping onto those networks, producing a vulnerable point by which those networks can be compromised.
