The industry journey toward interoperable and secure building automation systems began a long time ago with the initial release of BACnet and has continued with its subsequent enhancements and extensions. Through the end of 2019 our journey brought us to broad interoperability covering a wide range of building controls subsystems and requirements. Security, however, was accomplished outside of BACnet and thus did not benefit from the interoperability BACnet provides. In 2020 BACnet Secure Connect, or BACnet/SC was added to the standard, and it pushed us further along the road by providing interoperable device authentication and message encryption. These are major advances, but they are not the end of the road.
There are other things we need to address, including interoperable message authorization, security certificate management and other system management functions. The BACnet Committee (SSPC 135) is working on these further enhancements to the standard. In addition, a collective industry effort is underway to move the industry further along the road. This effort is focused on interoperability in the context of IT infrastructure and best practices. Over the next few months, you will hear more about this work as it becomes more visible through industry forums and publications.
