Embodiment Construction

[0028] Smart building systems or cyber-physical system (CPS) infrastructure may be vulnerable to cyber-attacks. Detection and response methods detect conditions that may result from such cyber attacks. However, known systems and methods detect anomalies in a system without distinguishing between a cyber attack and a physical system failure, such as a failure of a particular system in a CPS. The systems and methods described herein distinguish between cyberattacks and system failures, and provide automated responses when cyberattacks are detected.

[0029] figure 1 An example smart building system 10 is schematically shown. The building system 10 includes a first building 12a and a second building 12b. In some examples, building system 10 may include additional buildings. For example, building 12a may include a heating, ventilation, and cooling (HVAC) system 30a , a door lock system 32a , a lighting system 34a , an elevator system 36 , and an electric vehicle charging syste...

Abstract

A method for a building system includes determining a relationship between first data from a first building device and second data from a second building device. It is determined whether there is an anomaly based on the relationship. An automatic targeted control response is provided if the anomaly indicates an attack.

Description

Background technique [0001] The present disclosure generally relates to a defense and response system for buildings. [0002] Buildings, such as university buildings, office buildings, residential buildings, etc., include multiple electric drive systems. Some or all of these systems are intelligent systems that include Internet or other network connections that facilitate remote control and operation of building systems over computer networks. [0003] Because of their connection to computer networks, smart building systems can be vulnerable to hacking, malware, or other malicious activity. In addition, smart and non-smart building systems may behave abnormally due to malfunctions or other operational irregularities. Unusual activity can be the result of an individual attempting to attack a building, an individual attempting to use one or more building systems to indirectly attack other building systems, the power grid, or other buildings, or unexpected non-malicious activit...
