Current SSPC 135 Happenings from SSPC 135 Chair Coleman Brumley

The latest meeting of the SSPC 135 Plenary and all the working groups took place in a hybrid format in Tampa during the ASHRAE Annual Conference in June 2023. This meeting was notably active, marked by the release of a new addendum 135- 2020cp, which focuses on cybersecurity. Specifically, this addendum discusses Authentication and Authorization and how BACnet/SC addresses it. This is an important topic and there are many stakeholders eager to see this progress. BACnet/SC offers a method to secure communication channels between devices.
