What Is Cybersecurity?
Cybersecurity is the practice of protecting digital systems, networks, devices, and data from unauthorized access, disruption, damage, or theft. In the built environment, cybersecurity covers everything from controllers on rooftop units and building automation systems (BAS) to cloud services, mobile apps, and software platforms that manage maintenance, assets, space and occupancy.
Historically, building equipment was not connected to the internet. Today, with the rise of smart buildings, cloud-based asset management, and Wi-Fi-enabled HVAC equipment, facility systems are part of the internet of things (IoT). This connectivity unlocks powerful data but requires rigorous protection to prevent bad actors from disrupting building operations, exposing sensitive data or causing safety risks and financial harm.
While IT cybersecurity protects emails and bank records, OT (operational technology) cybersecurity protects the physical systems that run the building:
- Building automation systems (BAS): Preventing hackers from taking control of controllers like Trane Tracer® SC+ or Symbio® units.
- Connected equipment: Securing smart chillers, rooftop units, and wireless thermostats (such as Trane Air-Fi® sensors) that communicate over wireless networks.
- Facility data: Protecting sensitive information regarding building occupancy, security codes, and energy usage patterns stored in cloud platforms like Trane Connect or Nuvolo.
Cybersecurity should be a focus of facility managers and building owners for several reasons:
- Operational continuity: A cyberattack on your BAS could shut down HVAC systems in the middle of summer, creating unsafe conditions for occupants and costly downtime.
- Data protection: Building management systems collect vast amounts of operational data. Securing it prevents competitors from gaining insights into your operations and protects tenant privacy.
- Regulatory compliance: Many industries, including healthcare, finance and government, have strict cybersecurity requirements. Failing to secure building systems can result in fines, failed audits, or loss of certifications.
- Liability and insurance: A breach originating from an unsecured building system could expose your organization to lawsuits, especially if it compromises tenant data or causes physical harm.
- Long-term system health: New controls can help increase energy efficiency, boost team productivity, and enhance cybersecurity, while newer systems maintain compliance as energy standards become more rigorous.
As you adopt smarter building technologies, from BAS to integrated workplace management systems (IWMS), cybersecurity should be part of the conversation from day one. It's not about avoiding connectivity; it's about connecting securely. Learn more by contacting your local Trane representative today.
