Today, more than ever, the need for secure building management systems is paramount in the realm of facilities management. Building management systems, or BMS, are part of the larger ‘Internet of Things’ (IoT) and provide an array of different services, such as energy efficiency, access control, fire safety and more. As these systems are becoming increasingly interconnected, the risk of cyber-attacks and data breaches has become more prevalent.
What is a Building Management System (BMS)?
A BMS is a computer-based system that controls, monitors and optimizes a building’s environment, such as heating and cooling, fire safety, and energy efficiency. A BMS connects to different types of sensors, controllers and systems throughout a building. This enables the BMS to constantly monitor and optimize the building’s operation, react to changes in the environment, and provide valuable data for decision-making.
Why is Building Management System Security Important?
With the rise of the ‘Internet of Things’, building management systems are increasingly relying on connected devices, such as sensors and controllers, to share information and control various systems within a building. This connectivity increases the risk of cyber-attacks, such as data breaches, malware, and ransomware. A security breach of a BMS could have potentially serious consequences, including financial loss, disruption to operations, and reputational damage.
Best Practices for Building Management System Security
To ensure a BMS is secure, there are certain best practices that should be followed. These include:
- Ensure all IoT devices are securely configured and regularly maintained.
- Implement authentication and access controls to limit who can access the system.
- Always use secure communication protocols when transferring data.
- Monitor the system for any suspicious activities or changes.
- Enforce regular backups to ensure the system can be restored in case of a data breach.
Conclusion
The security of building management systems is essential for facilities management. Adopting best practices, such as secure configuration and access controls, will help ensure a BMS remains secure and free from malicious attacks. By taking the necessary steps to ensure the security of a BMS, facilities managers can help protect their buildings and the data they contain.
