Protecting the building automation infrastructure
For financial reasons, a growing number of building operators wish to access their company networks for the overall BACnet data exchange. This is not without its risks, as this essentially enables unauthorised parties access to the building automation infrastructure. To date, however, encryption and user-specific authentication were not foreseen in the BACnet protocol. Following enhancement of the standard for data exchange between different manufacturers’ devices with the according security mechanisms, MBS reacted by complementing the tried-and-tested BACnet router UBR-01 with security functions based on the protocol requirements.
