Laying the Conduit
How VMware Cloud Foundation turns IEC 62443 zones, IEC 62351 crypto requirements, and Enhanced CAF obligations into operational infrastructure — NSX for the network fabric, vDefend for firewalling and threat detection, Avi for load balancing and TLS offload, Live Site Recovery for DR, and Advanced Cyber Compliance for cyber recovery.

Drawing the Conduit
IEC 62443 zones and conduits replace the air gap — and IEC 62351 gives them something to be made of. Applied to a composite UK transmission substation, with the regulatory framework that makes the work obligatory.

The Air Gap Was Always a Fiction
How the IT/OT air gap dissolved over thirty years — from the Purdue Model through Stuxnet to virtualised SCADA — and what the attackers found when they got through.
Infrastructure
The Substation Network
How IEC 61850 replaces copper trunks with Ethernet — merging units, process buses, zero-recovery-time redundancy, and the virtualisation debate that's splitting the industry into camps.
Infrastructure
Making the Substation Intelligent
Why every grid operator on the planet faces the same problem — sites that outlive their equipment, equipment that outlives the software protecting it, and a three-millisecond deadline that hasn't changed since the 1960s.
