Smart buildings integrate HVAC, lighting, security, elevators, and other systems. Cyber attacks could cause building operation disruptions or even physical security incidents.

Attack Scenarios

HVAC system infiltration then attacking the IT network (Target data breach initial entry point). Elevator control system manipulation causing physical security risks. Fire system deactivation creating security vulnerabilities. Energy management system attacks affecting power supply.

Security Architecture

Deploy BACnet/IP protocol security gateways. Strict segmentation between Building Automation and IT networks. Real-time monitoring of abnormal building control system traffic. Regular penetration testing and security assessments.

Conclusion

Building automation systems should be considered as part of critical infrastructure, adopting the same or even higher security standards as IT networks.
