Building automation is shifting from proprietary networks to IP networks, creating a large impact on network management as there will be an influx of Building IoT devices on the network. These devices will need to be securely added to the network and then provisioned in the Building Management System (BMS).  This process will involve Information Technology (IT) administrators and the provisioning in the BMS system will involve Operational Technology (OT) administration. To reuse an existing, managed IT network, the devices on that network need to be evaluated by IT managers before onboarding to the network, since being on the same network can cause disruption for the other services that are running on the same network. Using the same IT network for IoT devices will avoid duplicating a second network in the building, with the additional benefit of reusing the existing operational infrastructure to manage the devices.

It is for these reasons that the same security requirements should be applied for Building IoT devices as for other devices managed by the IT department. The initial step is…
