In my role at Cochrane Supply & Engineering, my focus includes helping the design community understand building IoT, integration, and OT cybersecurity.
One of the most useful tools that an engineer can provide in clarifying the overall architecture is a systems integration drawing.
The drawing should show the connected systems, integration platform, OT network, enterprise connections, cloud applications, and remote access paths.
NEEVE is an example of a platform that supports Zero Trust remote access, role-based permissions, and auditing.
Develop the systems integration drawing, put clear requirements in the specifications, and establish how the completed system will be verified.
