BACnet Secure Connect (BACnet/SC) is an addendum to the existing BACnet specification and utilizes the TLS protocol to authenticate devices on your building automation network and encrypt their communication.
Every device on the BACnet/SC network has their identity verified prior to being granted access to communicate on the network. Without being authenticated, unverified devices cannot join the network, and cannot communicate with other verified devices.
All of the information going through the BACnet/SC network is end-to-end encrypted, preventing bad actors from intercepting and decoding traffic. This prevents hackers from altering system performance and operation.
Information sent through a BACnet/SC connection is verified to be authentic, unaltered data from the original source.
BACnet/SC is built on the core technology used by websites and web browsers to browse the internet, giving the user complete security. TLS security is among the latest security protocols, and elevates BACnet to a level of security trusted by governments and financial institutions around the world for encryption.
Despite the complexity of the secure communication algorithm used by BACnet/SC, Delta Controls has developed an extremely simple and effective method of managing your Secure Connect networks and devices. The system integrator, with no special training, performs a one-click approval of a device requesting to join the BACnet/SC network. This click triggers the TLS key generation, certificate signing, and schedules certificate renewal, all without any further action required from the user.
Once a device is authenticated, the security is invisible; the system looks and performs exactly as expected. The end user has no additional steps or tasks required in their daily operation of the building automation system.
BACnet/SC is a new BACnet Data Link Layer, providing another way to send BACnet traffic between two networks. Traditional BBMD routing is effective at connecting BACnet devices that reside on separate networks, however it requires firewall exceptions to enable two-way communication, and the traffic between BBMD devices is completely open and unencrypted. BACnet/SC replaces the need for BBMD devices, thus closing a major security hole that has been present throughout the building automation world for many years.
While Delta Controls has developed BACnet/SC to achieve the full level of interoperability intended by BACnet, to date we are the only system available with the BACnet/SC protocol. Interoperability with other vendors’ products and previous generation Delta Controls products comes with BACnet; a network may contain a mix of BACnet/SC and non-BACnet/SC controllers, allowing a staged upgrade path towards bringing the entire system up to the latest security.
