Cybersecurity in Building Automation: Ensuring Effective Protection Against Attacks

Digitalization is making its way into the building sector, along with the increasing networking of automation systems and IT solutions. While this brings advantages, such as resource-efficient operations, it also presents risks: The attack surface for cybercriminals is expanding.

Until now, comprehensive measures and processes focusing on securing building automation systems against network attacks have been limited. This leaves unprotected control systems vulnerable to the complexities of the IT world.

Secure Networking of Smart Buildings – in New Construction and Existing Applications

Thanks to modern automation, buildings can be transformed into smart buildings, offering high energy efficiency and increased comfort. Resilient automation products and current security features ensure safe building operations.

Smart buildings present vast energy-saving opportunities. However, how can networking and digitalization advance without exposing building operators to potential building automation threats? This is a major challenge for today’s building automation suppliers. At WAGO, cybersecurity is a top priority: all solutions are protected with state-of-the-art security technologies to make unauthorized access as difficult as possible. Meanwhile, our open and interoperable automation solutions provide you with the flexibility to implement energy efficiency projects without compromise. ull security, combined with flexibility, ensures long-term success in complex building automation projects.

Security with WAGO Controllers

WAGO provides the expertise and technology that enables buildings to be designed and constructed in a more energy-efficient and secure manner. WAGO's PFC200 and PFC100 Controllers play a key role in this because they come with an integrated firewall that protect from network attacks. They are also equipped with cloud connectivity, which optimally protects building data from unauthorized data attacks. Information is directly encrypted in the controller and then transmitted to the cloud via IPsec or OpenVPN.

Secure Communication with BACnet/SC

BACnet Secure Connect (BACnet/SC) revolutionizes communication in smart buildings. It enhances one of the most widely used protocols in building automation by adding an additional network layer for secure data transmission. This extension includes encryption and authentication features to ensure secure data transfer and prevent unauthorized access. The key benefit: BACnet/SC is compatible across versions, enabling the approximately 25 million BACnet® devices installed worldwide to be upgraded with modern IT security functions.

Energy-Efficient and Secure Projects

In Saarlouis, a city in Saarland, a combination of WAGO PFC200 Controllers and WAGO Cloud are used. An example is monitoring the municipal energy plant and well system to find ways to economize their operation. The controllers collect the data and transmit it to the cloud, where the city administrators can access it from any location. If, for example, the systems in the central energy plant are running inefficiently, then the employees immediately recognize this, in the context of asset management, and can initiate countermeasures. They do not have to worry about security tasks because WAGO, or the WAGO technology equipped with security features, takes over these functions.
