In an Internet of things (IoT) world, smart buildings with web-enabled technologies for managing heat, lighting, ventilation, elevators and other systems pose a more immediate security risk for enterprises than consumer technologies. The increasing focus on making buildings more energy efficient, secure and responsive to changing conditions is resulting in a plethora of web-enabled technologies. Building management systems are not only more tightly integrated with each other, they are also integrated with systems outside the building, like the smart grid.
