SIS was engaged to develop a risk-driven Enterprise-Wide Security Architecture (EWSA) for delivering secure information systems – both for Information Technology (IT) and Operational Technology (OT) environments.
The designed detailed how OT systems should be designed, built and operated across all layers of the ISA-95 model.
The following architectures were developed in sequence:
- Conceptual Architecture Design – Strategic view of processes (attributes);
- Logical Architecture Design – Information flows & transformations (security services);
- Physical Architecture Design – Data flows & system interactions (security mechanisms); and
- Component Architecture Design – Protocols & step sequences (tools, products, standards).
