A computer-implemented method and building automation system, the building automation system including a network of electronic devices connected in electronic communication. The method includes initiating an electronic security scan of the controller. The controller electronically assesses security vulnerabilities of the controller, including identifying one or more of a validation of whether the controller is protected by a firewall or other network security device, identifying which communication ports are open, identifying and verifying an Ethernet and Wi-Fi configuration of the controller, determining whether any routers communicating with the controller are protected by the firewall or other network security device, determining whether the controller is running an up-to-date software or firmware version, and determining a listing of software applications and versions installed on the controller. The controller calculates a risk score and listing of recommendations for resolving security vulnerabilities of the controller based on the electronically assessing security vulnerabilities of the controller.

Network security management for a building automation system

Apparatus, systems and methods for ascertaining the occupancy of a building are presented. The building is divided into one or more control zones which correspond to physical areas of the building associated with controllable modules, such as HVAC units, lighting, irrigation, or other environmental features such as fountains, music, video, and the like. Zone parameters define how zone devices shall react to the number of occupants located in the particular zone. A building control system detects individual mobile devices in and around the building, and determines the locations of each device by using trilateration and/or location services. The identified mobile devices act as proxies for building occupants. The locations of these devices are correlated with the locations of the zones in the building, and the building control system then adjusts the operating parameters of the zone based on the number of devices present in the zone.
