Until recently, monitoring of building management systems (BMSs) security has never been an issue. The threat of cyber attacks now looms large, however, meaning more attention must be paid to the integrity of a BMS.
While well-understood protocols exist for monitoring and protecting computers and data centres, BMSs are often ignored, despite being a growing concern inside and outside of the buildings industry.
Building and access control systems are computers that monitor and control building operations, such as air-conditioning, electrical power, electronic card reading, elevators, fire alarms and fire suppression, heating, lighting, ventilation and video surveillance. These systems are increasingly connected to other information systems and the internet.
While this advancement in technology improves automation and enables remote operations, it also exposes these systems to possible cyber attacks.
