IT/OT Convergence Security by Kai London
Convergence is already done — the data is flowing, the accounts are shared, the vendor is dialled in. What is usually missing is the security architecture that makes it survivable. This book supplies it, in terms engineering and IT can both sign.

What is inside
The industrial DMZ
Reference designs for the boundary layer — brokers, jump hosts, data diodes — and the failure modes each one hides.
Identity across the divide
Directory design, privileged access and service accounts when the plant cannot depend on a corporate domain to run.
Data flows and cloud
Historians, analytics and remote monitoring — moving the data out without opening a route back in.
Unified monitoring
One detection capability covering both estates, with OT context that stops the SOC from escalating a normal process event.
Joint incident response
Who decides to isolate, who decides to stop the process, and how those two decisions are rehearsed together.
Operating model and ownership
Budget, accountability and the RACI that keeps convergence from becoming a permanent argument.
Who it is for: CISOs inheriting industrial estates, OT security leads, enterprise and control-system architects, and IT operations teams now responsible for plant-adjacent infrastructure.
Convergence is not a project you approve. It is a condition you are already living in.
