BACnet/SC: Secure data communication for buildings

Property owners and IT managers have one concern in common: OT communication in the building network should be safe from attacks. With the addition of BACnet/SC (“secure connect”) this problem is solved. By utilizing a BACnet/SC router SAUTER can integrate existing networks and a BACnet/SC-capable building and energy management system.

 

The latest addition to the BACnet standard combines security aspects with new possibilities for data exchange. This has a significant impact on building automation, as BACnet/SC paves the way for using existing IT networks.

BACnet/SC solutions from SAUTER

SAUTER Vision Center (SVC) is already designed to fit the new security standard – even in the cloud. In the hub-and-spoke principle of the BACnet/SC network, SVC can assume the role of primary hub. The hub is the central element of the network and configures and controls all communication of the encrypted BACnet objects.

The SAUTER Vision Services cloud solution provides a cost-conscious entry into the world of modern building management, as the cloud provider bears the maintenance costs for hardware and software. Furthermore, updates are available immediately and automatically.

In addition to BACnet/SC-capable software, SAUTER also offers the new BACnet/SC router (modu630-RT) as hardware for expanding existing BACnet installations to include encrypted communication. The BACnet/SC router can be used both as a BACnet/SC primary hub and as a BACnet/SC failover hub.

With BACnet/SC-capable software and hardware from SAUTER, existing BACnet installations can be BACnet/SC encrypted.

Moving to BACnet/SC

The demand for secure communication is huge and the answer in building automation is BACnet/SC. We support integrators and operators throughout the entire handling process of a project, from planning and engineering to commissioning and maintenance. Existing BACnet/IP systems can be upgraded to BACnet/SC gradually and flexibly as required. Where SAUTER Vision Center is already installed, an extended licence makes the changeover straightforward.

The tried-and-tested SAUTER CASE Suite is used to configure the BACnet/SC router and the encrypted communication in existing IT networks. The router will be available from early summer 2023. For more information get in touch with our sales department.

Our commitment

Being a member of the BACnet Interest Group Europe (BIG-EU), SAUTER is actively involved in how it develops further. Our company has expert representatives in various international BIG-EU working groups. The aim of this community is to promote the standard, to enable the public exchange of data and ensure compatibility between building automation components. Constructive feedback from users and implementers is continually reviewed and incorporated as the standard is developed further.

SAUTER Head Office was the target of a cyber security incident on November 20, 2024. SAUTER’s IT department immediately activated, well defined, internal emergency plans. All IT systems were completely isolated and shut down to successfully prevent the attack from spreading. External cybersecurity experts and data forensics specialists then began to check all systems and restore them securely. This process is unfortunately time-consuming, but absolutely necessary to ensure that the cyber-attack does not continue at a later date.


The SAUTER websites have been affected by the emergency operation and are available again with immediate effect.


There are currently no concrete indications that our customers' infrastructures have been compromised in any way by SAUTER devices. It appears to be an opportunistic incident with no clearly recognisable long-term goals or systematic attacks. The situation does not currently suggest that there is a targeted, sustained threat to the affected systems.
