IoT attack surfaces and defences
The hackability of smart buildings
Imagine your team has assembled for an important meeting . The video conference room beside the data centre is humming with the muted sound of air conditioning equipment . Suddenly , security cameras come alive , watching every move you make . Then , the window shades drop , the doors lock and the heater blasts full-force . The video conference screen wakes up . Ominous red letters glow in the darkness , Welcome to the haunted house of hacks ...
You hear colleagues swearing as they try to turn off the video using the touchscreen automation controller . You see cell phones glowing around the conference table . Cell service is dead . Heat warning lights begin to flash on and off . Sweating in the darkness , your mind rewinds past the images of your family .
You remember a meeting you had earlier in the week . OT Zero Trust . Never trust , always verify . You laugh because otherwise , you might cry . The humming from the air conditioners grows fainter as data centre systems shut down . You think you smell something strange , then you pass out . Is this a cheesy horror film or a real-world threat ?
42 % of the world ’ s energy is used in buildings . From special purpose buildings , such as data centres and hospitals , to hotels , office buildings and even our homes , building automation can improve energy efficiency , safety and comfort . Whether we ’ re working or living in a building , we expect good air quality , comfortable temperatures , adequate lighting and safety . Business automation systems can deliver . Those buildings that make use of these systems take in 6 % more rent and have a 15 % higher sales price . In part , this is because maintenance costs are roughly three quarters of the total cost of ownership . However , these benefits can only be realised if buildings are not ‘ haunted ’. Since building automation systems connect to the internet and to each other , they are vulnerable to cyberattacks that may haunt you with ransom demands or denial of service . In this situation , think of OT zero trust as the ‘ cybersecurity ghostbusters ’ of building automation systems . �
