Challenge
Newmont needed better visibility and supportability across a varied operational technology landscape. The aim was a globally standardised foundation that could accommodate individual field systems and allow core business functions to continue independently of corporate IT.
Contribution
Ian was the principal architect, designer, owner and implementer of Newmont’s Operational Technology Infrastructure Stacks (OTIS). He created the designs, documentation and diagrams, determined budgets and oversaw procurement.
He built the configurations and travelled to implement the stacks across six sites in Australia, Africa, South America and North America. His wider work also included implementation and formalisation of the Purdue network security model at Newmont.
Outcome
The common platform enabled Newmont’s global teams to help site OT teams manage and support their infrastructure. Consistent identity management, security policies, patching and maintenance provided a shared operational foundation.
Successful applications could be replicated between sites, including Newmont’s Advanced Process Control Supervisory System. Testing during implementation checked that the systems operated as designed.
