4.2.2 Understanding existing IT and OT networks

In addition to understanding business processes, organisations that are implementing an IoE solution must consider the existing IT and OT network infrastructures and operations.

Business managers must understand how the IT network users interact with the network resources and services and gather information about all internal and external access to the existing network infrastructure. Without full knowledge of who has access to the network and how it is used, the intended solution might not include some user requirements, or incorrectly identify user groups. Other considerations include identifying the existing network and infrastructure components, and capabilities, including support for traffic requirements, data storage, and security needs.

In addition to understanding IT network operations, business managers must also consider how current networks of OT systems operate. This includes knowing how the M2M connections currently take place, the information that is generated from these connections, and how this information is integrated into the current business processes. They must also identify any connectivity requirements, such as the use of proprietary protocols.
